Abstract
A device for retaining a supra pubic catheter having a moveable retainer axially moveable along the catheter.
Description
i r r I
FIELD OF INVENTION
This invention relates to a device for retaining a supra pubic catheter and particularly relates to a supra pubic catheter with a moveable device along a catheter for improved sealing characteristics as well as the use of the system and method relating thereto.
Background to the Invention Whether due to disease, stroke or Alzheimer's, a percentage of the population cannot urinate through their urethras. Such patients may be catheterized with a urinary catheter where the catheter is passed through the urethral of the patient until a distal end of the catheter is located in the patient's bladder. Thereafter, an expandable balloon is expanded to lodge the distal end of the catheter in the bladder. During catheterization, with a urinary catheter, urine drains from the bladder through the catheter, and through a drainage tube attached to a proximal end of the catheter to a drainage bag for collection therein.
Another system comprises the use of supra pubic catheters where the catheter passes through the abdomeri wall of the patient until the distal end of the catheter is located in the bladder. This technique bypasses the urethra all together, and the bladder is connected to the outside of the body in the pelvic region. A surgical procedure is conducted where a stoma tunnel made of body tissue leads from the bladder to the outside of the abdomen.
Such supra pubic catheters have been used to drain urine by placing a urethral catheter through the tunnel or stoma. A balloon at one end, namely the distal end, is inflated with sterile water or saline inside the patient's bladder in order to keep the catheter in place.
Thus, fluid from the bladder exits through the hollow passageway of the catheter to the exterior of the patient's body.
Examples of such prior art devices and procedures are disclosed in U.S.

2003/0009079, US Patent No. 4,867,745 and US Patent No. 4,143,651.
Moreover, US Patent No. 4,888,000 discloses a supra pubic catheter inserted by way of a cannula which is positioned using a trocar, the trocar being withdrawn to leave the cannula in . ..

position through the wall of the bladder, allowing passage of the supra pubic catheter, the cannula being provided with means for subsequent removal from the catheter.
Also, US Patent No. 5,520,636 teaches a device for flushing the urinary bladder.
Furthermore, US Patent No. 6,350,255 illustrates a pad for use with a continent ostomy port which includes a body portion having a internal wall defining an aperture appropriately sized placed around a stoma, the body portion of the pad being sized and shaped for placement against the user's skin beneath a face place of an ostomy port. The pad is formed of a soft, flexible material to thereby cushion and protect the skin from contact with the ostomy port face plate.
One of the difficulties with the current technique and prior art devices resides in the fact that the inflated balloon does not stay in place, either due to patient's movement or the play in migration inwards and outwards of the catheter which breaks the seal. Furthermore, the weight of the saline filled balloon may cause leaking of air and fluid. Ideally, the fluid or urine drains from the bladder with the use of the relatively higher pressure in the bladder when compared to the atmosphere pressure in the drainage bag or the like, as well as due to the gravity. In those circumstances, where there is no seal, drainage relies on gravity alone.
In addition, when a good seal is not maintained, urinary leakage occurs. The patient is wet and in addition the weight of the patient in bed and the pressure on the skin increases a patient's risk of infection, skin breakdown and formation of decubitus ulcers. There is a general concern for decubitus ulcers in the sacrum and bilateral hips which manifest itself as Ishial tuberosities. If a patient already has decubitus ulcers in these areas with urine leakage on such dressing affects the effectiveness of the dressing and the medication under the dressing, which ultimately leads to various complications.
Moreover, leakage of air and fluid around catheter provides an avenue for infection. If air and or fluid can leak out, organisms can be introduced through this access. The catheter outside the skin and any organisms on this catheter will be deposited in the bladder by the migration and play of the catheter.
Moreover, it has been documented that, without properly securing the urethral catheter, the stoma over time, becomes larger and eventually causing insertion of a larger catheter. This I I I

causes the patient more trauma and discomfort. Much of the existing difficulties may stem from the fact that urethral catheters are used in supra pubic catheter applications.
Accordingly, there is a need for improved apparatus and method as well as system for a supra public catheter.

Description of the Invention In the description which follows, like parts are marked throughout the specification and the drawings with the same respective reference numerals. The drawings are not necessarily to scale and in some instances proportions may have been exaggerated in order to more clearly depict certain features of the invention.
Figure 1 illustrates a prior art urethral or urinary catheter 2 which has one end of distal end 4 adapted to be placed through a stoma 6 of a body 8 towards a bladder 10. The stomal tunnel is produced by a trocar under sterile conditions. The catheter 2 has a "Y" branch 12 where one of the branches 14 is adapted for inserting saline solution through the catheter so as to inflate the balloon 18 in a manner well known to those persons' skill and art.
Moreover, the abdomen 8 generally comprises of the public wall.
In the system illustrated in Figure 1, the catheter 2 has one end or distal end 4 inserted directly into the bladder through the supra pubic area. The balloon 18 of the catheter 2 is then inflated within the bladder, by introduction of saline solution through branch 14 by way of example, and then pulled snuggly to occlude the opening 20 from the bladder to the stomal tunnel 22. In particular the catheter has two coaxial passages one that communicates with the balloon 44 and branch 50 , and the other that communicates with the holes 43 at the distal end to drain urine through end 19 . One of the problems encountered in the prior art is that the balloon moves (hence the seal is broken) due to the flexibility of the rubber or silicone catheter, the weight of the fluid filled balloon 18. along with any slight movement of the patient or catheter.
Figure 2 illustrates and describes therein a catheter 40 having at its distal end 42 an inflated balloon 44. In particular, the catheter 40 is inserted directly into the bladder 46 through the supra pubic area through a stomal tunnel 48 produced by the surgical use of the trocar (not shown) in the abdomen or pelvic wall. The balloon 44 on the catheter 40 is then inflated within the bladder by means of the "Y" branch 50 in a manner well known to those persons skill in the art. Upon inflating the balloon 44, the catheter is then pulled snuggly to occlude the opening from the bladder 46 to the stomal tunnel 48. Figure 2 also discloses that one of the branches 16 communicates with the remainder of the catheter to present a passage way 17 which permits voiding of urine through the catheter out the exit 19.
A flange 52 is disposed along the catheter. The flange, more particularly described in Figure 3 consists of a sleeve and hollow cylindrical portion 54 having a hole or bore 58 there through.
Cylindrical portion 54 is symmetrical about axis 60. The retainer device 52 also comprises the radially extending flange portion 56.
Moreover, the abdomen 8 generally comprises of the public wall.
In the system illustrated in Figure 1, the catheter 2 has one end or distal end 4 inserted directly into the bladder through the supra pubic area. The balloon 18 of the catheter 2 is then inflated within the bladder, by introduction of saline solution through branch 14 by way of example, and then pulled snuggly to occlude the opening 20 from the bladder to the stomal tunnel 22. In particular the catheter has two coaxial passages one that communicates with the balloon 44 and branch 50 , and the other that communicates with the holes 43 at the distal end to drain urine through end 19 . One of the problems encountered in the prior art is that the balloon moves (hence the seal is broken) due to the flexibility of the rubber or silicone catheter, the weight of the fluid filled balloon 18. along with any slight movement of the patient or catheter.
Figure 2 illustrates and describes therein a catheter 40 having at its distal end 42 an inflated balloon 44. In particular, the catheter 40 is inserted directly into the bladder 46 through the supra pubic area through a stomal tunnel 48 produced by the surgical use of the trocar (not shown) in the abdomen or pelvic wall. The balloon 44 on the catheter 40 is then inflated within the bladder by means of the "Y" branch 50 in a manner well known to those persons skill in the art. Upon inflating the balloon 44, the catheter is then pulled snuggly to occlude the opening from the bladder 46 to the stomal tunnel 48. Figure 2 also discloses that one of the branches 16 communicates with the remainder of the catheter to present a passage way 17 which permits voiding of urine through the catheter out the exit 19.
A flange 52 is disposed along the catheter. The flange, more particularly described in Figure 3 consists of a sleeve and hollow cylindrical portion 54 having a hole or bore 58 there through.
Cylindrical portion 54 is symmetrical about axis 60. The retainer device 52 also comprises the radially extending flange portion 56.
In particular, the inner diameter of the hole 58 is sized so as to be slidably moveable along the longitunal axis 70 of catheter 40 in the region between the pelvic wall 49 and the proximal end 72 of the catheter 40, yet frictionally engage the outer diameter of catheter 40 when contacting the epidermal skin layer of the patient.
More particularly in one embodiment shown the hole 58 has capturing means 59 disposed interiorially of the hole 58. In particular the capturing means comprise a plurality of internally disposed projections or rings 59 . Therefore the catheter 40 which is comprised of stretchable material is adapted to be received co axially within hole 58 and ride past the rings 59 . Once the retaining device is placed in the desired position the flexible nature of the retainer and cather relaxes and the rings 59 assist in retaining the retainer 52 in the desired position on the catheter.
The retainer 52 also includes one wall 60 which is adapted to contact the pelvic wall 49. In the embodiment shown in Figures 2 and 3, the catheter 40 is inserted directly into the bladder 46 through the supra pubic area through stomal tunnel 48. The balloon 44 and the catheter 40 is inflated within the bladder 46 and pulled snuggly to occlude the opening from the bladder 46 to the stomal tunnel 48. The retainer 52 is then slidably disposed along the axial length 70 (exterior of the body of the patient) towards the balloon 44 so as to secure the balloon 44 under slight tension in its ideal location thereby creating a substantially closed or sealed system. In other words the length of catheter between the balloon 44 and the disc 52 contacting the exterior skin is under slight tension.
The system described herein comprises:
(a) Placing a supra pubic catheter through a stomal tunnel from the outside skin of the abdomen of the patient to the bladder;
(b) Inflating a balloon disposed at one end of the catheter, in said bladder to maintain said one end of the catheter in said bladder;
(c) Moving a retainer along the catheter towards the abdomen to draw said catheter balloon against the bladder.

The retainer 52 also includes one wall 60 which is adapted to contact the pelvic wall 49. In the embodiment shown in Figures 2 and 3, the catheter 40 is inserted directly into the bladder 46 through the supra pubic area through stomal tunnel 48. The balloon 44 and the catheter 40 is inflated within the bladder 46 and pulled snuggly to occlude the opening from the bladder 46 to the stomal tunnel 48.

With the system described herein, the retainer 52 holds the balloon over the inner, namely the bladder side opening to the stomal tunnel thereby providing a chance from the mucosa in the tunnel to dry and crust thus permitting healing to take place. Thereby, the opportunity for infection is minimized thus improving the patient comfort and providing the least disruption to the body image.
The system described herein provides the following advantages:
1. Reduces leakage from the stoma opening, due to a seal created from the flange and balloon.
2. The catheter stays in place, as the flange secures the catheter from any type of movement within the stoma.
3. The skin breakdown is significantly reduced, because the leakage is stopped since the stoma is sealed by the balloon secured in place by the retaining device.
4. Infection to the stoma area is reduced when the seal is create with the retainer, inhibiting any foreign matter from entering the stoma tunnel, thereby lowering the incident of Urosepsis and sepsis with air and fluid.
5. With a seal, the stoma has a chance to heal; since air contacts the normal mucosa in the stomal tunnel thus allowing granulation and healing.
6. Stoma enlargement is minimized.
7. Patient comfort and body image is significantly improved, because the seal keeps the area from leaking, giving the patient peace of mind that they will not have leakage in public.
8. Physical activity of the patient is significantly improved since the seal keeps the area from leaking which intern allows the patient the freedom to participate in activities they normally would not with previously used catheters.

Moreover, the catheter can be comprised of plastic such as bio compatible polymers, including silicone, rubber, silicone elastomers, polyurethane, silicone copolymers, polypropylene and/or similar materials or combination thereof typically used in the art.
The flange can be comprised of the similar material.
Furthermore the invention comprises the kit which includes the supra pubic catheter and retainer.
Moreover other embodiments of the flange may be used to frictionally engage the catheter in the operable position described above and releasable from the catheter in a second inoperable position .
Figures 5 and 6 illustrate another embodiment of the invention which shows the flange having the cylindrical portion 54 cut axially and the flange portion 56 cut radially as shown, so that the flange can be opened as shown in Figure 6 and closed as shown in figure 5.
Generally speaking the flange material comprises of a flexible material such as plastic including biocompatible polymers such as silicon, rubber, silicon elastomers, polyurethane silicon copolymers, polypropylene and/or similar materials or combinations thereof typically used in the art. Such materials have a memory so that the flange as shown in figure 6 would tend to move to a closed position as shown in figure 5.
Accordingly, the flange shown in figure 6 could be manipulated so that the cut edges 57 and 59 of the cylindrical portion and the cut edges 61 and 63 of the flange portion 56 could be spread apart so as to receive the catheter 40 as shown in figure 5. The flange as shown in Figure 7a and 7b can be equipped with Velcro material . In particular, the Velcro material 90 can comprises of loop means which is adapted to be received by hoop means 94 in the manner well known to the persons skilled in the art. Accordingly, the flange can thereby be secured to the catheter as previously discussed. Alternatively, the Velcro material shown in figure 7b can be pulled apart to the position shown in figure 7a. Furthermore, the Velcro material 94 and 96 can extend further along the cylindrical portion 54 as well as the flange portion 56 so that the edge 57 can extend beyond the edge 59 so as to make a smaller diameter bore 58. In this manner, the edge of flange 61 would also extend beyond edge 63. In this embodiment the internal corner 65 of the flange shown in figure 6 would ride up so as to contact along the inner circular edge 67.
The flange can be comprised of the similar material.
Furthermore the invention comprises the kit which includes the supra pubic catheter and retainer.
Moreover other embodiments of the flange may be used to frictionally engage the catheter in the operable position described above and releasable from the catheter in a second inoperable position .

In this manner, the edge of flange 61 would also extend beyond edge 63. In this embodiment the internal corner 65 of the flange shown in figure 6 would ride up so as to contact along the inner circular edge 67.
Alternatively, as shown in figure 8, adhesive tape 80 and 82 can be utilized so as to secure the flange frictionally along the catheter as previously described.
Figures 9a and 9b illustrate another embodiment of the invention whereby the cylindrical portion 54 includes the slit 55 having retaining shoulders 57 and 59 as shown which are adapted to be clasped and held in place by a slidable channel 61 as shown. The flange portion also includes similar retaining shoulders 51 and 53 with slidable channe171.
Figure 10a and 10b illustrate another embodiment of the invention whereby the cylindrical portion of the flange includes a recess to selectively releasably receive a projection 43 as shown.
Finally, figure 11 shows another embodiment of the invention which has a tapered cylindrical portion 53 with indicia or marks 3, 5 and 7 which correspond to different sized outer diameter of catheters. Accordingly, the friction fit between the inner bore 58 of the flange can be selected by cutting along the mark 3, 5 or 7 for the appropriate sized diameter to frictionally fit with the catheters previously described. For example markation line 3 may indicate a three millimeter diameter catheter while markation line 5 can indicate a 5 millimeter diameter catheter and markation line 7 indicate a 7 millimeter outer diameter catheter. Thereafter, the outer diameter of the cylindrical portion of the flange can be cut along one of the lines so as to present a flange having an appropriately sized inner diameter to frictionally fit with the outer diameter of the flange.
Various embodiments of the invention have now been described in detail. Since changes in and/or additions to the above-described best mode may be made without departing from the nature, spirit or scope of the invention, the invention is not to be limited to said details.
Figures 9a and 9b illustrate another embodiment of the invention whereby the cylindrical portion 54 includes the slit 55 having retaining shoulders 57 and 59 as shown which are adapted to be clasped and held in place by a slidable channel 61 as shown. The flange portion also includes similar retaining shoulders 51 and 53 with slidable channe171.
