Abstract
A male urinary incontinence control device (10) including a first element (12) for applying preferential pressure to the penis shaft (14) between the lateral superficial veins (18) and the central dorsal vascular group (20), and a second element (28) for applying pressure ventrally to the penis shaft (14) at the urethra (30) and the corpus spongiosum (32) thereby substantially or completely closing the urethra (30) and preventing or limiting the flow of urine through the urethra (30). Both longitudinally and transversely oriented lower bolsters are disclosed.
Description
- This application is a continuation-in-part of international application number PCT/US99/03836,filed Feb. 19, 1999 (pending).
- 1. Technical Field
- This invention generally relates to medical appliances and, more particularly, to a device used to control urinary incontinence of a male patient.
- 2. Discussion
- Male urinary incontinence is a long-recognized medical condition which can pose an embarrassment to men whose natural urethral valve or sphincter is no longer capable of controlling the flow of urine from the bladder. Urinary incontinence can arise from a variety of causes, including disease, surgery, neurological dysfunction, malformation of the urethral valve, physical deterioration accompanying advancing age, and other causes. Externally applied absorbent pads and internal catheters connected to collection bags are currently used as solutions to the problem of incontinence. Each of these solutions ultimately entails the external collection of the urine which escapes the bladder. Unfortunately, collection devices such as these can often be uncomfortable, inconvenient, unsanitary, offensive, unreliable and even inadequate during use.
- A variety of other devices are known for more actively regulating or controlling male urinary incontinence, rather than merely externally capturing or collecting urine. Some of these other devices include clamps or valves which are surgically implanted, positioned around and compressing the urethra. The clamp or valve is actuated in one way or another to permit the flow of urine through the urethra. These invasive devices have several drawbacks. The most significant of these drawbacks is the risk and cost associated with performing the implant surgery.
- Other commonly employed devices for the control of incontinence are non-invasive devices or appliances which include a strap, band, cuff, clamp, cradle, or other member which encircles the penis shaft. A device of this type is positioned about and tightened around the penis shaft until sufficient pressure is applied to the urethra and the corpus spongiosum to substantially or completely close the urethra. The device is loosened or removed to permit the flow of urine through the urethra when appropriate.
- A wide variety of non-invasive type devices are known in the art. Such devices can include single or plural members which are flexible or rigid. Some devices include a projection intended to lie beneath the urethra and corpus spongiosum to apply a sealing pressure to the urethra and corpus spongiosum. This projection can be rigid or resilient, or can even be an inflatable sac. This last construction is shown in U.S. Pat. No. 4,800,900 (issued to G. J. French on Jan. 31, 1989, and herein after referred to as ‘the '900 patent’), and is particularly advantageous in that deflation of the sac reduces the pressure applied to the urethra sufficiently to allow urination without requiring removal of the device from the penis shaft.
- Devices of the encirclement type usually permit sufficient tightening of the device around the penis shaft to prevent or substantially reduce the leakage of urine through the urethra. Unfortunately, sufficient tightening of the encirclement type device almost universally results in the application of an unacceptable and sometimes painful amount of pressure to tissues other than the urethra and corpus spongiosum. In particular, virtually all devices of this type apply undue pressure to the superficial dorsal vein, the deep dorsal veins, and the dorsal arteries and nerves. This grouping of veins, arteries, and nerves will be referred to as the central dorsal vascular group throughout the present disclosure.
- Devices of this general type are often subject to other drawbacks as well. Some are difficult to properly position on the penis shaft. Others are relatively complex in construction, and therefore relatively expensive to manufacture. Some provide poor adjustability to the particular patient using them. Further, wearing many of these devices can be quite uncomfortable, and virtually impossible to withstand for more than a few hours at a time.
- In light of the above, a need appears within the industry for a device for controlling male urinary incontinence which avoids applying undue pressure to the superficial dorsal vein, the deep dorsal vein, the lateral superficial veins and the dorsal arteries and nerves of the penis shaft, while ensuring that sufficient pressure is applied to the urethra and the corpus spongiosum to prevent or substantially reduce leakage from the urethra. A need also exists for a device which provides for a relatively precise selection of the dorsally and ventrally applied pressures. The needed device would avoid inflicting pain, trauma and/or damage to the skin and underlying tissues of the penis shaft when used. It would be desirable for such a device to be comfortably worn by the patient for an entire day without removal, except for removal to permit urination. It would further be desirable for such a device to be relatively inexpensive in construction, and relatively easy both to properly position on the penis shaft, and to remove for urination.
- The foregoing problems are solved and a technical advance is achieved in an illustrative male urinary incontinence control device which is particularly useful in that it is more comfortable to wear and use than prior devices, yet provides adequate closure of the urethra so as to prevent or substantially reduce leakage of urine through the urethra. The present invention can most simply be considered as an improvement in a strap, band, cuff, clamp or cradle type incontinence control device, the improvement comprising the inclusion of a means (such as a pair of projections or bolsters) which applies pressure preferentially at the specific areas between the lateral superficial veins and the superficial dorsal vein, the deep dorsal vein and the dorsal arteries and nerves. The superficial dorsal vein, the deep dorsal vein and the dorsal arteries and veins can, for practical purposes, be considered comprised within a single group located very near the top center of the dorsal surface of the penis shaft. As previously mentioned, this grouping will be referred to as “the central dorsal vascular group”. Thus, the control device of the present invention includes a means which applies pressure preferentially at the specific areas between the lateral superficial veins and the central dorsal vascular group.
- “Preferentially” (or “preferential”) should be understood as meaning that the pressure applied to the penis shaft by the pressure-applying means is greater at these specific areas than the pressure applied elsewhere to the penis shaft, save perhaps for the pressure applied ventrally to the urethra and the corpus spongiosum. The device of the present invention also applies pressure ventrally to the urethra and the corpus spongiosum, however, with the result that the urethra can be closed or substantially closed, while undue pressure on the superficial dorsal vein, the lateral superficial veins, the deep dorsal vein and the dorsal arteries and nerves is avoided. “Substantially” means that leakage through the urethra when the device is in place is reduced to as low as about one to six percent of the patient's daily urine output, typically only about 36 to 75 ml and 20 to 40 ml depending on the embodiment of the device, of a daily outflow of about 1200 to 1500 ml.
- This improvement is preferably embodied in a male urinary incontinence control device in which three projections or bolsters are carried on arms of a generally C-shaped resilient member. The words “projections” and “bolsters” are equivalent for the purposes of the invention, and “bolsters” should be understood to be a generic term, encompassing not only “projections,” but also all equivalents of them, which extend from the device towards the penis shaft, or which otherwise provide for the preferential application of pressure. The arms of the resilient member are joined by, and preferably unitarily formed with, a spring means. The arms are pivoted towards one another and held in a position by a clip or closure means disposed substantially opposite the spring. Two of the bolsters abut the penis shaft dorsally in the specific areas mentioned above, while the third bolster abuts the penis shaft ventrally at the corpus spongiosum and the urethra. The projections or bolsters are preferably composed of a material softer than or equal to that of the resilient member. Further, the third or ventral bolster can be the inflatable sac (25) disclosed in the '900 patent, cited above. The entirety of the disclosure of the '900 patent is expressly incorporated herein by reference.
- The present invention is particularly advantageous in that it avoids applying undue pressure to the lateral superficial veins and the central dorsal vascular group while ensuring that sufficient pressure is applied to the urethra and the corpus spongiosum to prevent or substantially reduce leakage through the urethra. Unexpectedly, the positioning of the dorsal pressure-applying means of the control device of the present invention avoids the application of undue pressure to the deep arteries in the corpi cavernosa, even when the applied pressure is sufficient to close or substantially close the urethra. This decreases the risk of discomfort during use of the device of the present invention. The device permits a relatively precise selection of the dorsally and ventrally applied pressures by adjusting the spring means and by correctly selecting the length of the closure means. The present invention substantially reduces or avoids the pain, trauma and/or damage to the skin and underlying tissues of the penis shaft during use when compared to the use of other encirclement type devices. The device of the present invention can be comfortably worn by the patient for an entire day (for example, as much as eighteen hours) without removal, except, of course, for removal to permit urination. The control device of the present invention is relatively inexpensive in construction, and the device is relatively easy both to position properly on the penis shaft, and to remove for urination. Indeed, when the device incorporates a sac similar to the type disclosed in U.S. Pat. No. 4,800,900, the device need not be removed for urination at all.
- One aspect the present invention is directed to a male urinary incontinence control device having a first means for applying preferential pressure to the penis shaft at areas between the lateral superficial veins and the central dorsal vascular group, and a second means for applying pressure ventrally to the penis shaft at the urethra and the corpus spongiosum. The second pressure-applying means can simply be the ventral portion of any strap, band, cuff, clamp, cradle or the like which engages the penis shaft and applies pressure for closing the urethra. Preferably, however, the first and second pressure-applying means each comprise an arm carrying on them the projections or bolsters mentioned above. Also, each bolsters of the top can include a slit receiving the associated arm through it, so that the bolsters are movable along the arm on which they are carried. This permits precise fitting of the device to the diameter of the penis shaft of the particular patient wearing it.
- Alternatively, the ventral bolster can include an inflatable sac. In such a case, the device of the present invention preferably further includes the valve and syringe assemblies associated with the sac as disclosed in the '900 patent. Preferably, however, the shape of the sac in the present invention will be somewhat different from the shape shown in the referenced patent. In particular, the sac in the present invention will be relatively longer in one direction (in a direction parallel or transverse to the urethra), and relatively shorter in its other direction.
- The dorsal and ventral arms of the first and second pressure-applying means are preferably unitarily and continuously formed with a spring means which connects them, generally yielding a C-shaped device. Also, the arms and the spring means are preferably formed as a leaf with ramped edges, composed of stainless steel or a medical grade plastic material.
- In a second aspect, the present invention is directed to a device of the type disclosed above, and specifically including a particular combination of elements. More particularly, in its second aspect the present invention is directed to a male incontinence control device having a first means for applying preferential pressure to the penis shaft at areas between the lateral superficial veins and the central dorsal vascular group, a second means for applying pressure ventrally to the penis shaft at the urethra and the corpus spongiosum, and a spring means connecting the first and second pressure-applying means. The spring means being unitarily formed with the first and second pressure-applying means, wherein the first pressure-applying means includes a dorsal arm and a pair of dorsal bolsters on the dorsal arm facing the second pressure-applying means, the dorsal bolsters being movable along the dorsal arm, and wherein the second pressure-applying means includes a ventral arm and a ventral bolster on the ventral arm facing the first pressure-applying means. In this aspect, the dorsal and ventral arms of the first and second pressure-applying means, and the spring means, are continuously formed as a C-shaped leaf composed of stainless steel or a plastic, wherein the first pressure-applying means includes a relief means located over the dorsal arteries and nerves, the relief means being a portion of the dorsal arm of the first pressure-applying means spaced away from the dorsal arteries and nerves, and wherein the dorsal bolsters each include a slit through which the dorsal arm is received. The ventral bolster of the second aspect includes either a slit through which the ventral arm is received, or an inflatable sac, and the device further includes a clip connectable to the first and second arms opposite the spring means, the clip limiting movement of the first and second arms away from one another or the penis shaft.
- In a further aspect of the invention, a variant off of either aspect mentioned above, the second pressure-applying means is specifically oriented transverse to the penis shaft and urethra. As such, the second pressure-applying means may or may not include a bolster oriented along an arm which carries it.
- In still another aspect of the invention, and being another variant of the above mentioned aspects, at least one of the first and second pressure-applying means, comprised of an arm, is of a modified cross-sectional shape. In particular, the cross-sectional shape of at least a portion of the arm is of a modified “V-shape”. Notably, the apex or point of the V-shape is toward the penis shaft; when the device is applied thereto.
- In yet another aspect, the present invention is directed to an improvement in a strap, band, cuff, clamp or cradle type urinary incontinence control device attachable to the penis shaft and applying pressure ventrally to at least the urethra and corpus spongiosum, the improvement being means on the device for applying preferential pressure to the penis shaft at areas between the lateral superficial veins and the central dorsal vascular group, such that adequate pressure to substantially reduce leakage of urine through the urethra can be applied without unduly interfering with the flow of blood in the penis shaft.
- Again, as mentioned above, the incontinence control device of the present invention possesses several significant advantages, most notably that it avoids the undue application of pressure to the lateral superficial vein and the central dorsal vascular group (the superficial dorsal veins, the deep dorsal vein, and the dorsal arteries and nerves) while permitting complete or substantially complete closure of the urethra, thereby comfortably preventing significant leakage of urine from the bladder.

- With reference first to FIGS. 1 and 2, a male urinary
incontinence control device 10 according to the present invention is shown. Thecontrol device 10 includes a first means 12 for applying preferential pressure to thepenis shaft 14 atareas 16 between the lateralsuperficial veins 18 and the central dorsalvascular group 20. The central dorsalvascular group 20 is used in the present description to include the superficialdorsal vein 22, the deepdorsal vein 24 and the dorsal arteries andnerves 26. Thecontrol device 10 also includes a second means 28 for applying pressure ventrally to thepenis shaft 14 at theurethra 30 and thecorpus spongiosum 32. The first and second pressure-applyingmeans penis shaft 14 to close or substantially close theurethra 30 and prevent leakage, while avoiding the application of undue pressure to thepenis shaft 14 at the lateralsuperficial veins 18, the central dorsalvascular group 20, and thedeep arteries 34 in thecorpi cavernosa 36. The pressure applied dorsally by the first pressure-applyingmeans 12 is designated in FIG. 2 by thearrows 3 8, while the pressure applied ventrally by the second pressure-applyingmeans 28 is designated by thearrow 40. - The first pressure-applying
means 12 preferably includes adorsal arm 42 and a spaced pair of dorsal bolsters 44 movably carried on thedorsal arm 42. The dorsal bolsters 44 face and project towards the second pressure-applyingmeans 28. The first pressure-applyingmeans 12 preferably also includes a relief means 46 located over the central dorsalvascular group 20. The relief means 46 encompasses ashort portion 48 of thedorsal arm 42 which is located above the central dorsalvascular group 20. Thisshort portion 48 is formed as abend 50 in thedorsal arm 42 which has a much smaller radius of curvature than that (if any) of thedorsal arm 42. This causes theshort portion 48 to be raised up and away from the surface of thepenis shaft 14, thereby reducing the possibility of applying undesired pressure to the central dorsalvascular group 20. The dorsal bolsters 44 are positioned on each side of theshort portion 48. - The second pressure-applying
means 28 preferably includes aventral arm 52 and a ventral bolster 54 movably carried on theventral arm 52. The ventral bolster 54 faces and projects towards the first pressure-applyingmeans 12. Thedorsal arm 42 includesedges normal plane 60 of thearm 42 as shown in FIG. 3. While not shown, theventral arm 52 also includesedges edges penis shaft 14 while applying or wearing thecontrol device 10. - The dorsal bolsters44 and the ventral bolster 54 can be formed in any convenient shape suited to provide the pressures indicated above. The ventral bolster 54 of the preferred embodiment is generally firmer than the
penis shaft 14, while the dorsal bolsters 44 of the preferred embodiment are generally equal to or softer than thepenis shaft 14. More particularly, the firmness of the dorsal bolsters 44 should match that of thepenis shaft 14 when wrapped in the manner described below. The bolsters 44 and 54 are preferably composed of a resilient, medical grade material capable of withstanding repeated cleaning and/or sterilization. For example, the bolsters 44 and 54 can be formed from short segments of medical grade rubber tubing, or from several pieces of tubing interfitting one another with one having an outside diameter generally equal to the inside diameter of a second outer piece of tubing. The bolsters 44 and 54 may have either blunt or tapered longitudinal ends. Tapered ends for the bolsters 44 and 54 are preferred, so as to avoid any sharp edges that could cause damage to the skin or tissue of thepenis shaft 14. - The ventral bolster54 of the preferred embodiment has a somewhat larger outer diameter than the dorsal bolsters 44. For example, the ventral bolster 54 preferably has a 25% to 67% larger outside diameter than the outside diameter of the dorsal bolsters 44. This difference is determined by the fact that the
suitable areas 16 between the central dorsalvascular group 20 and the lateralsuperficial veins 18 are less than the area below theurethra 30 and thecorpus spongiosum 32 where pressure is properly applied. Therefore, the diameters of the dorsal bolsters 44 should be less than the diameter of the ventral bolster 54. The diameter of the ventral bolster 54 should be minimized and the length should be maximized to the extent practical, so as to obtain the greatest reduction or stoppage of flow through the urethra 30 while minimizing the ventral pressure (arrow 40) applied by theventral arm 52. In contrast, the purpose of the dorsal pressure (arrows 38) applied by thedorsal arm 42 is to serve as an overall resistance to the ventral pressure (arrow 40). Since thesuitable areas 16 for the application of the dorsal pressure (arrows 38) are less than the area suitable for the application of the ventral pressure (arrow 40), it is preferable to make the dorsal bolsters 44 somewhat longer than the ventral bolster 54. This allows the dorsal pressure (arrows 38) to be kept as low as possible so that excess pressure on the central dorsalvascular group 20 is avoided in case of misalignment of the dorsal bolsters 44, while the ventral pressure (arrow 40) actually needed for adequate closure of theurethra 30 is also minimized. - Forming the bolsters44 and 54 from medical grade tubing makes it particularly simple to provide for the adjusting movement previously mentioned. Each of the dorsal bolsters 44 in the preferred embodiment includes a
slit 62 through which thedorsal arm 42 is received. The material of each bolster 44 presses against thedorsal arm 42 thereby keeping the bolster 44 in a desired position, while at the same time permitting each bolster 44 to be slid along thedorsal arm 42 to precisely locate each of the bolsters 44 over theproper area 16 to which pressure is to be applied. This adjusting movement allows thecontrol device 10 to be custom fit to a particular patient. The ventral bolster 54 can include acomparable slit 64 through which theventral arm 52 is received in a similar manner. - The
slits arms penis shaft 14 by having theslits slits arms penis shaft 14. Further, the increased distance between thearms penis shaft 14 allows the bolsters 44 and 54 to provide an increased amount of compressible material therefore improving the comfort and providing a more uniform pressure distribution. - Referring to FIGS. 4 and 5, another preferred embodiment of the present invention is shown to include a ventral bolster54 having an
inflatable sac 66. Thesac 66 can be secured to theventral arm 52 in a wide variety of ways. In the present embodiment, thesac 66 is detachably secured to theventral arm 52 by a hook-and-loop type fastener 68. Thefastener 68 readily permits precise positioning of theinflatable sac 66 beneath theurethra 30 andcorpus spongiosum 32. Preferably, a length of the loop portion of thefastener 68 is secured to theventral arm 52 thereby allowing an appropriate range of adjustability, while the hook portion of thefastener 68 is secured to thesac 66. This arrangement is preferred since any exposed loop portion is less likely than the hook portion to harm thepenis shaft 14. - The
inflatable sac 66 can be similar to or identical to the inflatable sac (25) disclosed in the previously referenced U.S. Pat. No. 4,800,900 (the '900 patent). Thesac 66 is inflated by actuation of avalve 70, shown schematically, connected to thesac 66 by atube 72. Thetube 72 can be similar to or identical to the tube (27) disclosed in the '900 patent. Thevalve 70 represents any suitable valve structure for supplying and releasing an inflation gas, such as air. However, thevalve 70 most preferably represents the entire valve assembly (30) and syringe assembly (50) shown in the '900 patent. The relevant descriptions of these elements in the '900 patent are expressly incorporated herein by reference. - Unlike the sac (25) in the '900 patent, the
inflatable sac 66 in thecontrol device 10 of the present invention is oriented so that its longest dimension lies parallel to theurethra 30 andcorpus spongiosum 32, rather than perpendicular to them. Theinflatable sac 66 may also be somewhat narrower than the sac (25) of the '900 patent. Thesac 66 is preferably only slightly wider than the diameter of theurethra 30 and thecorpus spongiosum 32. In a typical application of the present invention, thesac 66 is about 1 inch long and about ¼ to ⅜ inch wide. It is also preferred that thesac 66 have a wall profile height which provides for good vertical movement (that is, towards the penis shaft 14) in the central, longitudinal portion of thesac 66 when thesac 66 expands. - With reference to FIGS. 1, 2, and6, the
incontinence control device 10 is shown to include a spring means 74 connecting the first and second pressure-applyingmeans means control device 10. However, in the preferred embodiment the spring means 74 instead urges the first and second pressure-applyingmeans clip 76 or other limiting element engages the first and second pressure-applyingmeans means penis shaft 14 to control the flow through the urethra 30 (FIG. 6). Theclip 76 can, in its simplest form, include a pair ofbuttons 78 held apart by arigid wire 80. Thebuttons 78 engage the first and second pressure-applyingmeans ventral arms arms respective slots wire 80 is disposed. Thus, theclip 76 serves to limit movement of the dorsal andventral arms penis shaft 14. Thewire 80 of the preferred embodiment is rigid so as to make it easier to engage theclip 76 with the first and second pressure-applyingmeans clip 76 or the distance between thebuttons 78, can be adjusted to control the pressure being applied by the dorsal bolsters 44 and the ventral bolster 54. - The spring means74 of the present invention is preferably unitarily formed with the first and second pressure-applying
means ventral arms means leaf 90. The C-shapedleaf 90 is composed of a suitable material including, but not limited to, metal or plastic. In particular, stainless steel has provided excellent results during testing. The spring means 74 may alternatively be a separate spring (not shown) which connects separate dorsal andventral arms - Referring to FIGS. 7 and 8, a comparison is shown between two preferred embodiments made in accordance with the teachings of the present invention. FIG. 7 shows the
control device 10 generally disclosed throughout the description to this point. FIG. 8 shows an alternate embodiment of thecontrol device 10′ which is narrower than thecontrol device 10 of FIG. 7. The readers attention is first directed to the arcuate shape of thedorsal arm 42′. Thearm 42′ provides a radius of curvature “r” which effectively eliminates the need to provide the relief means 46 of thecontrol device 10. The radius of curvature “r” also allows the effective hinge point of the spring means 74′ to shift downward toward the ventral bolster 54′ when compared to that of thecontrol device 10. Further, theventral arm 52′ of thedevice 10′ also provides an arcuate shape which is in the same direction as that of thedorsal arm 42′. The radius of curvature “R” of theventral arm 52′ is preferably greater than the radius of curvature “r” of thedorsal arm 42′. The configuration of thedevice 10′ as presented allows for a narrower overall width of the control device while still providing sufficient adjustability to accommodate different diameters of the penis shaft 14 (not shown). - An additional advantage of the
control device 10′ which results from the lowered effective hinge point and from the unique arcuate curvature of thearms 42′ and 52′ as described, is that the pressure applied by the dorsal bolsters 44 and indicated by thearrows 38′ is rotated to direct the resultant force more directly toward theurethra 30. Experimental use of thecontrol device 10′ has thus far provided improved comfort and the ability to wear thedevice 10′ for an even greater period of time without discomfort. One skilled in the art will readily recognize that modifications and alterations to the particular radii of curvature, “r” and “R”, may be required or desirable to provide a series or family of differentsized control devices 10′ which will be most effective and comfortable to a variety of patients. - Use of the
control device 10 of the present invention for controlling male urinary incontinence is relatively straightforward in light of the present description. In use, it is recommended that the skin of thepenis shaft 14 is first covered with a light coating of ointment to protect the skin from prolonged exposure to any urine which may flow past the urethra 30 while wearing thedevice 10. A 40% zinc ointment or other ointment used to prevent diaper rash is recommended. The skin of thepenis shaft 14 is next covered with one or more layers of a flannel or Jersey knit wrap. This knit wrap also protects thepenis shaft 14 from theedges ventral arms device 10, and helps to retain the cross section of thepenis shaft 14 in a reasonably normal shape before application of thedevice 10. - In addition, one or more layers of “COBAN”® or other similar adhesive wrap material can be applied as a bandage wrap to further maintain the cross sectional shape of the
penis shaft 14, and to provide a gripping surface for the bolsters 44 and 54 to work against. The adhesive wrap also helps maintain the location of the bolsters with respect to each other, keep the lower bolster under the urethra and the top two bolsters straddling the central vascular group. The bandage wrap further serves as a partial barrier to urine, protecting the knit wrap and the skin of thepenis shaft 14. For simplicity, the ointment, knit wrap, and bandage wrap are collectively designated in FIG. 2 as a single layer ofwrap 92. - Next, the dorsal and ventral bolsters44 and 54 are properly positioned on the dorsal and
ventral arms clip 76 is opened or removed and thecontrol device 10 is slipped onto thepenis shaft 14 from the side. The leading edge of thedorsal arm 42 should be positioned about ¼ inch or more from the rim of the glans (not shown) of thepenis shaft 14. With thedevice 10 held in an approximately correct position with respect to thepenis shaft 14, the two dorsal bolsters 44 are moved on thedorsal arm 42 until positioned over theareas 16 between the lateralsuperficial veins 18 and the central dorsalvascular group 20. This places the dorsal bolsters 44 almost directly over thedeep arteries 34 in thecorpi cavernosa 36. The ventral bolster 54 is then moved on theventral arm 52 until it is positioned under theurethra 30 and thecorpus spongiosum 32. Proper positioning is checked visually. For example, the patient can rotate thepenis shaft 14 upward and sight down along the length of theshaft 14 to determine the precise orientation of thedevice 10. This is particularly important with regard to the position of the ventral bolster 54. - The proper positioning of the ventral bolster54 in the above embodiments should be considered to be critical to the successful use of the
control device 10. There is very little tolerance for misalignment since leakage flow through the urethra 30 will vary in direct proportion to any degree of misalignment. The patient should be reminded of this, but should also be advised that there will be an initial learning curve for the proper positioning of the ventral bolster 54. A visible indicator can be used to mark the proper locations of the bolsters 44 and 54 on the dorsal andventral arms - The ends82 and 84 of the
arms clip 76 in theslots areas 16 in the direction of thearrows 38, and pressure being applied by the ventral bolster 54 to theurethra 30 and thecorpus spongiosum 32 in the direction of thearrow 40, thereby preventing any leakage or any substantial leakage of urine through theurethra 30. - This description of the procedure for using the
control device 10 of the present invention may make such use appear to be a bit cumbersome. However, the procedure in fact takes only a few minutes to accomplish. It readily becomes second nature to the patient, and is a small price to pay for the comfort, security and convenience which thedevice 10 provides. - More particularly, urination while wearing the
control device 10 is simple. If the ventral bolster 54 is other than the inflatable sac 66 (previously described and shown), theclip 76 is disengaged from theslots ends arms urethra 30 and permitting the flow of urine through theurethra 30. When the bladder is voided, the ventral bolster 54 is again accurately aligned with theurethra 30 and thecorpus spongiosum 32, and theclip 76 is reinstalled by the patient. Alternatively, if thedevice 10 includes a ventral bolster 54 having theinflatable sac 66, thevalve 70 is actuated to deflate thesac 66 which permits the flow of urine through theurethra 30 without requiring thedevice 10 to be opened. Once the bladder is voided, thevalve 70 is used to inflate thesac 66 and once again apply pressure in the direction of thearrow 40 thereby closing theurethra 30. - While the present invention has been described in terms of a particular preferred embodiment, one skilled in the art will readily recognize that the principles of the disclosed
control device 10 can be applied to a wide variety of other incontinence control devices. Accordingly, the present invention can be considered as a broad improvement in any strap, band, cuff, clamp, or cradle type urinary incontinence control device which is attachable to thepenis shaft 14 and which applies pressure ventrally to at least the urethra 30 and thecorpus spongiosum 32. More particularly, the improvement consists of providing on a device of this type the previously disclosed first means 12 for applying preferential pressure to thepenis shaft 14 at thesuitable areas 16 between the lateralsuperficial veins 18 and the central dorsalvascular group 20, whereby adequate pressure to substantially reduce leakage of urine through the urethra 30 can be applied without unduly interfering with the flow of blood in thepenis shaft 14, and without causing pain or trauma to the patient despite wearing thecontrol device 10 for a prolonged period, for example, up to eighteen hours per day on a continuous daily basis. - The male urinary
incontinence control device 10 of the present invention is preferably composed of medical grade materials which can be cleaned and/or sterilized by conventional procedures before and after use. Conveniently, theincontinence control device 10 can be made of a variety of relatively inexpensive materials of suitable resiliency and rigidity. - Several practical considerations regarding use and construction of the
control device 10 according to the present invention merit mention. When the ventral bolster 54 is not aninflatable sac 66, theclip 76 must be carefully dimensioned to the particular patient using thedevice 10. In contrast, use of theinflatable sac 66 as the ventral bolster 54 may make it possible to adapt a single size of thecontrol device 10 to a variety of patient sizes. This of course requires thesac 66 to be inflatable over an adequate range of volumes and/or heights. - Further, the
clip 76 need not be a separate piece but can be hinged or captured at one end to one of the dorsal andventral arms clip 76 can also be adjustable in length, for example, by having a threaded rod or post in place of thewire 80, and a threaded wheel or nuts in place of one of thebuttons 78. The end of the rod or post can be peened or capped to prevent loss of the wheel by inadvertent threading of the wheel free of the post. One particular embodiment of the device as just described is shown in FIGS. 9 and 10. - FIG. 9 shows a portion of the second pressure-applying
means 28, and particularly a portion of theventral arm 52. Ahole 96 is provided at theend 84 of thearm 52 to receive afirst end 98 of a threadedfastener 100. Thefirst end 98 of thefastener 100 is designed to be captured on and remain fastened to thearm 52. Lockingnuts 102 are threaded on asecond end 104 of thefastener 100 and once properly located can be rotated in directions opposite one another such that thenuts 102 axially engage the threads of thefastener 100. This axial engagement locks thenuts 102 in an infinitely variable desired location. Once thenuts 102 have been properly adjusted and locked, thefastener 100 can be shortened by breaking off any excess which extends above the nuts 102. Break-offnotches 106 are provided to allow for easy shortening of thefastener 100, as shown in FIG. 10. Acap 108 is placed over thesecond end 104 of thefastener 100 and may, but need not, completely or partially cover the nuts 102. Thecap 108 in the preferred embodiment is made of a soft plastic material and reduces or eliminates the possibility of causing harm to thepenis shaft 14 and improves comfort for the patient when wearing thecontrol device 10. - Referring to FIGS.11-13, the retaining function of the
clip 76 can also be accomplished with a short section of fine stainlesssteel bead chain 110. Thechain 110 includes a plurality of beads having spaces there between. FIG. 13 shows a detailed view of a section ofchain 110 whereinadjacent beads 112 provide a spacing indicated as “X”. In the preferred embodiment, the spacing “X” is equal to or less than ⅛ inch thereby providing proper incremental adjustment of thecontrol device 10. The degree of closure of the dorsal andventral arms chain 110 and between theadjacent beads 112 receives theends arms end 114 of thebead chain 110 can be permanently attached to either of theends ventral arms bead chain 110. Further, thebutton 78 includes a slot 116 so that thebutton 78 can be selectively positioned along thechain 110. - Referring to FIGS. 1 and 14, it is noted that when the
control device 10 of the present invention is to be applied to a patient on a long-term basis it may be highly desirable to prevent theend 84 of theventral arm 52, as well as thebutton 78 received in theslot 88 in theend 84, from damaging the skin of the scrotum. In a preferred embodiment, asmooth plastic cover 122 is placed over theend 84 of theventral arm 52 and the associatedbutton 78. The plastic of thecover 122 is preferably soft and flexible, and conveniently can be about {fraction (1/16)} inch thick. As shown in FIG. 14, thecover 122 is rounded on a first,closed end 124 and includes anopening 126 opposite theclosed end 124. Thecover 122 also includes aslot 128 extending from theopening 126 to accommodate thewire 80 of theclip 76. Thecover 122 covers any sharp edges or comers on theend 84 of theventral arm 52 or the associatedbutton 78, thereby presenting a completely smooth surface to the skin of the scrotum. - While the dorsal and
ventral arms leaf 90. Moreover, like stainless steel, the use of plastics such as those disclosed will permit thedevice 10 to be easily cleaned, and will make thedevice 10 chemically inert or resistant to urine and to a zinc based or other ointment if used. - A variety of closure mechanisms can be used in place of the
clip 76, particularly when the ventral bolster 54 utilizes theinflatable sac 66. The dorsal and ventral bolsters 44 and 54 need not be medical grade latex or rubber tubing, but instead can be a relatively flexible elastomeric material including but not limited to urethane, vinyl, or a low density polyethylene. - It is contemplated that, particularly when the ventral bolster54 utilizes the
inflatable sac 66, thedevice 10 can be provided to the patient in the form of a kit. Such a kit would include thedevice 10 as described herein, plus a valve assembly and syringe assembly like those disclosed in the '900 patent. Further, the disclosed kit can include one or more spare valve and syringe assemblies which could be left at home, at a place of work, or in a vehicle to permit actuation of thedevice 10 without having to removing thedevice 10 in case the original (and detachable) valve and syringe assemblies become lost or are forgotten. - Referring now to FIGS. 15 and 16, a male urinary
incontinence control device 210, according to another embodiment of the present invention, is illustrated therein. Thecontrol device 210 includes a first means 212 for applying preferential pressure to thepenis shaft 14 atarea 16 between the lateralsuperficial vein 18 and the central dorsalvascular group 20. Thecontrol device 210 also includes asecond means 228 for applying pressure ventrally to thepenis shaft 14 at theurethra 30 andcorpus spongiosum 32. The first and second pressure-applyingmeans penis shaft 14 to substantially close the urethra and prevent leakage, while avoiding the application of undue pressure to thepenis shaft 14 at the lateralsuperficial veins 18, the central dorsalvascular group 20 and thedeep arteries 34 in thecorpi cavernosa 36. As seen in FIG. 16, the pressure applied dorsally by the first pressure-applyingmeans 212 is designated byarrows 238, while the pressure applied ventrally by the second pressure-applyingmeans 228 is designated byarrow 240. - The first pressure-applying
means 212 preferably include adorsal arm 242 and a pair of spaced apart dorsal bolsters 244 which may be movably carried on thedorsal arm 242. These dorsal bolsters 244 are similar to or the same as those previously discussed in connection with FIGS. 1 and 2 and therefore the prior discussion should be referred to in that regard. - The second pressure-applying
means 228 preferably includes aventral arm 252 and a ventral bolster 254 which may be movably carried on theventral arm 252. The ventral bolster 254 faces and projects towards the first pressure-applyingmeans 212. In this embodiment, however, the ventral bolster 54 is oriented so as to be transverse to thepenis shaft 14 andurethra 30 when thedevice 210 is applied to thepenis shaft 14. - As discussed above in connection with dorsal bolsters44 and the ventral bolster 54 of the embodiment seen in FIGS. 1 and 2, the bolsters 244 and 254 can be formed in any convenient shape suited to provide the pressures indicated above. Additionally, the ventral bolster 254 is generally formed so as to be firmer than the
penis shaft 14 with the dorsal bolsters 244 being equal to or softer than thepenis shaft 14. Further details regarding the materials of construction for the bolsters 244 and 254 as well as for the wrapping of the bolsters are as discussed previously in this detailed description. Reference thereto should be made in that regard. - Preferably, but not necessarily, the
dorsal arm 242 and theventral arm 252 are each formed withedges 256 and 268 which are angled to ramps from a normal plane 260 of the arm and as generally shown previously in FIG. 3. Theedges control device 210. - Referring now to FIG. 16, as will be appreciated from a review of the drawing in FIG. 15, the present and subsequent embodiments include numerous elements which are the same or analogous to elements discussed in the prior embodiments. To avoid repetition and undue length in this description, these elements bear reference numbers which correspond with the reference numbers used previously except that they are 200 series designation or higher. For example, the spring means74 illustrated in FIG. 1 corresponds with the spring means 274 illustrated in FIG. 15. Similarly, the
rigid wire 80 of FIG. 1 corresponds to therigid wire 280 of FIG. 15. Concerning these like elements, the reader is directed to refer back to the prior portions of the discussion regarding prior embodiments. The present sections should then be reviewed, bearing in mind the 200 and higher series designation for the present and subsequent embodiments. Where the present and subsequent embodiments differ from the prior embodiments, specific notation in this discussion will be made. - Referring now to FIG. 16, the embodiment of FIG. 15 is illustrated therein with one modification. The
ventral arm 252′, of the second pressure-applyingmeans 228′, is provided with a modified shape from the flat cross section seen in FIG. 15. More specifically, the cross-sectional shape of theventral arm 252′ is provided with an inverted “V-shape” as generally seen in FIG. 18. This inverted V-shaped cross-sectional shape is hereafter referred to as a “projection” 253′. Notably, the apex or point 255′ of theprojection 253′ is toward thepenis shaft 14. It is believed that the incorporation of the inverted V-shapedprojection 253′ on theventral arm 252′ will allow for a much lighter pressure to be used with thedevice 210′ in order to stop urine flow. In addition, by modifying the lower bolster 254′ so that it is oriented transversely to thepenis shaft 14, the critical location of the ventral bolster 254′, with respect to theurethra 30, is eliminated. All the user would have to do would be to align the upper bolsters 244′ to straddle the centralvascular group 20 while not closing the lateralsuperficial veins 18. Installing thedevice 210′ as such would be relatively easy since the top of a penis is easy to view and thedevice 210′ can be properly applied to the penis only by viewing the penis from above. Additionally, with the location of the lower bolster 254′ not being critical with respect to the urethra, the possibility exists to eliminate the adhesive wrap discussed above with prior embodiments as being positioned about each of the bolsters. Adevice 210′, according to the embodiment illustrated in FIG. 16, is illustrated in FIG. 17 properly applied to thepenis shaft 14. FIG. 18 shows a cross-sectional view through theventral arm 252′,projection 253′ and bolster 254′ of thedevice 210′ of FIG. 16. - Referring now to FIGS. 19A and 19B and20A and 20B are further embodiments of the present invention as illustrated therein. The
control device 310 includes a first means 312 for applying preferential pressure to thepenis shaft 14 at an area between the lateral andsuperficial vein 18 and the central dorsalvascular group 20. Thecontrol device 310 also includes asecond means 328 for applying pressure ventrally to the penis shaft at theurethra 30 andcorpus spongiosum 32. The first and second pressure-applyingmeans penis shaft 14 to substantially close theurethra 30 and prevent leakage while avoiding the application of undue pressure to the lateralsuperficial veins 18, the central dorsalvascular group 20 and thedeep arteries 34 in thecorpi cavernosa 36. - The first pressure-applying
means 312 includes adorsal arm 342 and a pair of spaced apart dorsal bolsters 344. The dorsal bolsters 344 are comprised of a combination of elements and each includes adorsal projection 343 formed in thedorsal arm 342 over which is received adorsal pad 345. Thedorsal projections 343 are spaced apart from one another along the length of thedorsal arm 342. Thedorsal projections 343 are illustrated as generally hemispherical indentations into thedorsal arm 342 and are oriented transversely to the length of thedorsal arm 342. Accordingly, theprojections 343 project in a direction toward the application of force by the first pressure-applyingmeans 312. While illustrated as being oriented transversely to the direction of thedorsal arm 342 and as extending completely thereacross, it is noted that other shapes and orientations for thedorsal projections 343 could be utilized. For example, theprojections 343 could be provided as hemispherical projections wholly contained within the lateral dimensions of thedorsal arm 342. - The
dorsal pads 345, seen in FIG. 20A, are adhesively or otherwise secured to the underside of thedorsal arm 342 so as to extend over thedorsal projections 343. Thedorsal pads 345 are provided as separate elements spaced apart from one another along thedorsal arm 342. Thepads 345 are formed of a closed or open cell foam or other material having the characteristics discussed above in connection with the prior embodiments. Alternatively, thepads 345 could be provided as a unitary pad so long as corresponding with thespace 347 between theillustrated pads 345 is provided therewith. The lateral edges 349 of thedorsal pads 345 are chamfered or beveled to prevent injury to the penis shaft while applying or wearing thecontrol device 310. - The second pressure-applying
means 328 includes aventral arm 352 and a ventral bolster 354. The ventral bolster 354 is comprised of aventral projection 353 and aventral pad 355. Theventral projection 353 is a V-shaped projection as discussed in connection with the embodiment of FIG. 16 and that discussion is herein incorporated by reference. Theventral pad 355 is adhesively or otherwise secured to theventral arm 352 over theventral projection 353. The length of theventral pad 355 is substantially the same as the length of theventral arm 352. As with thedorsal pads 345, theedges 359 of the pad are chamfered. - Additionally as seen in FIG. 20B, the width of the pads, both the
dorsal pads 345 and theventral pad 355 is wider than the underlyingarms pads - Application of the
device 310 to the penis is generally illustrated in FIG. 21. As seen in the figure, under application of pressure to the centralvascular group 20 and the lateralsuperficial veins 18, is avoided while theurethra 30 is occluded to prevent leakage therefrom. - FIG. 21 illustrates the retaining of the
device 310 to the penis through use of abead chain 311 that is permanently attached to anend ventral arm button 378 attached to thechain 311 and engageable with aslot 316 in theopposing arm device 310 in its closed position. As mentioned previously with respect to prior embodiments, the button is provided so as to be selectively positionable along thechain 311. - Referring now to FIGS.22A-22D, illustrated therein is the proper positioning of the longitudinal lower bolster of the earlier embodiments with respect to the urethra and misapplication thereof. FIG. 22A is diagrammatic illustration of the application of the longitudinal lower bolster to the urethra. In this figure, the longitudinal lower bolster is represented by the circle designated at 400 while the urethra is illustrated as this circle designated at 410. Upon the application of force to the
urethra 410 from the bolster 400, it is easily seen that misapplication of force by the bolster to the urethra will tend to move the urethra either to the left or to the right. As such, the urethra will not be properly occluded and the device may not work as intended. FIG. 22B illustrates a longitudinally oriented ventral bolster 54 (oriented with the shaft of the penis) and aligned with the urethra where upon clamping of the device may not occlude and close theurethra 30. FIG. 22C illustrates the urethra shifted to the left of the longitudinal ventral bolster 54 while FIG. 22D illustrates the urethra shifted to the right of the ventral bolster 54. In both of the latter figures, some leakage would occur. - With the transverse orientation of the embodiments seen in FIGS.17-20B (and FIGS. 23A and 23B discussed below), all of these misalignment problems are avoided and alignment of the penis and urethra with respect to the lower bolster is not critical, the device is easier to install and achieves less leakage.
- In a final embodiment of the invention, seen in FIGS. 23A and 23B, the
ventral arm 552 of the second pressure-applyingmeans 528 is provided with a curvature designed to cradle, position and center the penis in thedevice 510, relative to thedorsal arm 542 and theprojections 543 and bolsters 544. For clarity, the pads are not shown in this embodiment but would be employed in actual use. This curvature is generally concave when viewed from above and provides theventral arm 552 with acentral depression 560 beneath the bolster 544 of thedorsal arm 542. Thedorsal arm 542 itself is of the same constructions as provided in the embodiment illustrated in FIG. 19A while the ventral arm of that embodiment is modified with the curvature anddepression 560 mentioned above. Theventral arm 552 continues to contain aventral projection 553, which is of the construction and shape mentioned with the previous embodiment. Specifically, theprojection 553 has an inverted V-shaped cross-sectional shape with its apex pointing toward thedorsal arm 542. - Finally, while it is expected that the
incontinence control devices control devices device 10 can be much smaller than the large pads and diapers conventionally used for the complete capture of urine, and are much easier to use. - It should be clear from the foregoing disclosure that the
incontinence control device 10 of the present invention is particularly advantageous in a variety of ways. Most importantly, the present invention is advantageous in that it avoids applying undue pressure to the lateral superficial veins and the central dorsal vascular group while ensuring that sufficient pressure is applied to the urethra and the corpus spongiosum to prevent or substantially reduce leakage through the urethra. The disclosed positioning of the dorsal pressure-applying means unexpectedly avoids the application of undue pressure to the deep arteries in the corpi cavernosa, even when the applied pressure is sufficient to close or substantially close the urethra. The discomfort experienced during use of the device is thereby lowered. The present invention permits a relatively precise selection of the dorsally and ventrally applied pressures, by adjustment of the spring means, the curvature of the dorsal arm, and the selection of the length of the clip or closure means, if present. The present control device substantially avoids the pain, trauma and/or damage to the skin and underlying tissues of the penis experienced during the use of other devices of this type such that the device can be comfortably worn by the patient for an entire day. The control device of the present invention is relatively inexpensive in construction, is relatively easy to properly position on the penis, and is relatively easy to remove for urination. Indeed, when the device incorporates an inflatable sac of the type disclosed in U.S. Pat. No. 4,800,900, instead of a bolster or pad, the device need not be removed even during urination. - While the various embodiments are illustrated and discussed herein, it is noted that those embodiments where the lower bolster or pad is oriented transverse to the penis shaft and urethra are preferred. Applicants have found that the transverse orientation of the present invention offers several advantages including: 1) alignment with the urethra is no longer critical, 2) ease of use and application is increased and 3) leakage is reduced, by at least a factor of two.
- The details of the construction or composition of the various elements of the
incontinence control devices - The present invention is useful as a medical appliance for controlling male urinary incontinence, and therefore finds applicability in human and veterinary medicine. It is to be understood, however, that the above-described device is merely an illustrative embodiment of the principles of this invention, and that other devices and methods for using them may be devised by those skilled in the art, without departing from the true spirit and fair scope of the present invention as defined in the following claims.
