Description

COMPACT PACKAGED INTERMITTENT URINARY CATHETER
FIELD OF THE INVENTION
[0001] This invention relates to packages for urinary catheters. Some embodiments of the invention relate to methods of using such urinary catheters.
BACKGROUND

[0002] Intermittent catheters are typically used by patients suffering from urinary incontinence or by individuals unable to have voluntary urination. In our highly mobile culture, the ability to have the freedom to leave home for the day or longer is an important part of life. To accommodate this need single use catheters have been developed to allow patients to perform self catheterization. These catheters and their drainage tubes typically have a considerable length and are packaged in an elongated condition. It can require a considerable amount of space to store and transport enough catheters to accommodate a day long outing.

[0003] U.S. Pat. No. 7,682,353 B2 discloses an intermittent catheter kit that provides a catheter in short sections to be assembled at the time of use, but many users of the catheters have limited dexterity to assemble these catheters and may still need drainage tubes to reach a waste receptacle. A need still exists for an easy to use intermittent catheter that is compact and completely assembled upon opening the package.
Date recue / Date received 2021 -1 1-29 SUMMARY OF THE INVENTION

[0004] A first aspect of the invention is a compact packaged intermittent urinary catheter. The catheter has a longitudinally elongated intermittent urinary catheter retained within a longitudinally compacted elastic package.

[0005] In a preferred embodiment the compacted package is folded or coiled such that removal of one end of the package removes the other end of the package.

[0006] A second aspect of the invention is a method of using a catheter in accordance with the first aspect of the invention. The method includes the steps of (a) obtaining a compact packaged intermittent urinary catheter retained within a longitudinally compacted elastic package having a first longitudinal end and a second longitudinal end, (b) manually opening the first and second longitudinal ends of the package, (c) returning the package to a full longitudinal length, (d) removing a portion of the catheter from the package and inserting it into a urethra, and (e) using at least a portion of the package as a drainage tube for the catheter.

[0007] A further aspect comprises a compact package for an intermittent urinary catheter.
The package is longitudinally compacted and elastic and has an open extended state and a closed compacted state. The package further defines a longitudinally extending receiving chamber containing a lubricating medium. The package is sized and configured when in its compacted state such that a first longitudinal end of the package and a second longitudinal end of the package are aligned and attached together and removal of the first longitudinal end causes removal of the second longitudinal end and opening of the package.
Also, removal of Date recue / Date received 2021 -1 1-29 both first and second longitudinal ends permits the package to be converted to its extended state with both first and second longitudinal ends being open. The longitudinally extending receiving chamber is sized and configured when the package is in its open extended state to slidably receive a longitudinally elongated intermittent urinary catheter so that the lubricating medium coats the catheter exterior.

[0008] The compact package may be made from polyester, polyethylene, or a combination of the two materials. A line of weakness proximate the first longitudinal end of the package and the second longitudinal end of the package may be provided wherein the lines of weakness are aligned when the first longitudinal end of the package and the second longitudinal end of the package are aligned and attached together. Preferably, the compacted state of the package includes a single fold with the first and second longitudinal ends being joined together opposite the fold. Alternatively, the compacted state of the package includes a coiled configuration. The compact package may have a hinge to allow the package to be configured and arranged into its compacted state.

[0009] Additionally, the compact package may have at least one set of laterally extending dimples configured and arranged to allow the package to be folded into its compacted state.
The compact package may also have a biasing means configured and arranged to bias the package toward its extended state, such as a polymer member or at least one pressurized chamber.

[0010] A method of using an intermittent urinary catheter is also described including the steps of:
Date recue / Date received 2021 -1 1-29 a. obtaining, in its closed compacted state, the package for an intermittent urinary catheter as set forth in claim 1;
b. simultaneously removing the first and second longitudinal ends of the package so that both first and second longitudinal ends are open;
c. converting the package to its extended state;
d. inserting a leading end of an intermittent urinary catheter into the open first longitudinal end and passing the catheter through the longitudinally extending receiving chamber so that the leading end projects from the open second longitudinal end with lubricating medium coating an exterior surface thereof;
e. inserting the catheter leading end into a urethra; and f. using at least a portion of the package as a clean handling sleeve for the catheter.

[0011] The package preferably includes a single fold with the first and second longitudinal ends being joined together opposite the fold, and the step of converting the package to its extended state comprises unfolding the package.

[0044] Description

[0045] Construction Date recue / Date received 2021 -1 1-29

[0046] The invention is a longitudinally elongated intermittent urinary catheter 10 packaged in a longitudinally compacted elastic package 20 and a method of using the catheter 10.

[0047] FIG. 1 shows an embodiment of the catheter 10 sterilely packed inside a package 20. The package 20 is shown in full longitudinal length 21. The catheter 10 has at least a distal end 11, a proximal end 12, a longitudinal length 13, a lumen (not numbered), and at least one eyelet 14. The distal end 11 is preferably round ended to allow easy and pain free insertion into the urethra of a patient. The distal end 11 has one or more eyelets 14 to accommodate flow of the urine from the bladder through the lumen of the catheter 10.
Preferably the eyelets 14 are provided with rounded and or polished rims (not numbered) to increase comfort to the patient during insertion. The proximal end 12 of the catheter 10 provides an exit for the urine from the lumen.

[0048] The diameter of the proximal end 12 of the catheter 10 is preferably larger than the diameter of the distal end 11. The proximal end 12 may be any suitable shape to accommodate sliding along the full longitudinal length 21 of the package 20 without exiting the package 20.

[0049] The catheter 10 may be coated with a hydrophilic coating to provide a low friction surface when treated with a swelling medium. A swelling medium may be provided within the package 20 to provide a ready to use catheter 10. The use of hydrophilic coating and prepackaged swelling mediums with catheters 10 is well known in the industry. A
lubricant may also be provided in the package 20 to provide a low friction surface. Providing a lubricant in a catheter 10 package 20 is well known in the industry.
Date recue / Date received 2021 -1 1-29

[0050] The catheter 10 may have any desired longitudinal length 13 and shape effective for achieving the function of eliminating urine from the bladder of a male or female patient, including the hollow cylinder or tube shape as shown in FIGS. 1, 4, and 6.
Preferably, the longitudinal length 13 for an adult female catheter 10 is between 2-6 inches, the longitudinal length 13 of the adult male catheter 10 is between 10-16 inches, and the longitudinal length 13 of a pediatric catheter 10 is between 5-11 inches.

[0051] The catheter 10 may be constructed from any material possessing sufficient structural integrity, being light weight, and having a smooth finish, including specifically, but not exclusively, plastics such as polyethylene, polyvinyl chloride and polyurethane, etc.
The catheter 10 may be made without a softening agent also or with a softening agent allowing the catheter 10 to be pliable. Pliability is especially desired for the longer male catheter 10 to allow the catheter 10 to be stiff enough for insertion but to allow enough flexibility to manipulate through the longer urethra of the male anatomy. The catheter 10 may also be elastic like the package 20. Using an elastic catheter 10 would allow the catheter to be compacted to fit into a smaller package 20. An elastic and pliable catheter 10 may decrease the chances of the catheter 10 forming kinks if it is compacted in the package. An elastic catheter 10 may also aid the package 20 in resuming the full longitudinal length 21 upon opening of the package 20.

[0052] Preferably the catheter 10 is packaged in an elastic package 20. As shown in FIGS. 2-4 and 9, the package 20 is stored in a compact state defining a compact longitudinal length 22. The package 20 has a compact longitudinal length 22 that is less than the full longitudinal length 21. The elasticity of the package 20 may come from elastic material used Date recue / Date received 2021 -1 1-29 to form the package 20 or from a biasing means 70 incorporated into the package 20 wherein the package 20 is biased toward the full longitudinal length 21.

[0053] If an elastic material is used to form the package 20, the elasticity of the packaging material biases the package 20 to the full longitudinal length 21.
Preferably the package 20 is made from polyester, polyethylene, a combination of the two materials, Surlyn, polyprolene, or aluminum.

[0054] At least one biasing means 70 may also be used to provide the elasticity of the package 20. Any acceptable biasing means 70 may be used, such as but not exclusively, a spring. As shown in FIGS. 12 and 13, the biasing means 70, is sealed into or molded as part of the package 20. The preferred biasing means 70 is a polymer member or a pressurized chamber. The chamber may be filled with any suitable pressurized fluid such as water or a gas. To increase the elasticity of the package 20 more than one biasing means 70 may be used in a single package 20.

[0055] Preferably the inner surface 26a of the package 20 material is smooth to allow for ease in removing the catheter 10 for use and to prevent damage to the catheter 10. FIG. 1 shows the package 20 in a full longitudinal length 21. FIGS. 2-4 and 9 show the package 20 in its compact state where the compact longitudinal length 22 is less than the full longitudinal length 21.

[0056] The package 20 has a first longitudinal end 23 and a second longitudinal end 24 and defines an elongate catheter 10 receiving chamber 28 extending along a portion of the full longitudinal length 21 of the package 20. The catheter 10 is carried in the elongate Date recue / Date received 2021 -1 1-29 receiving chamber 28 with the distal end 11 of the catheter 10 located proximate the first longitudinal end 23 of the package 20. As shown in FIG. 1, a first embodiment of the package 20 may be constructed from a base sheet of material and cover sheet of material sealed along the edges 27 to form the catheter 10 receiving chamber 28 therein. See FIG.
7A. The first longitudinal end 23 and the second longitudinal end 24 are sealed after insertion of the catheter 10 in the receiving chamber 28. A second embodiment of the package 20 may also be constructed from a single base material folded upon it to provide a single sealed edge 27. See FIG. 7C. The first longitudinal end 23 and second longitudinal end 24 are then sealed after insertion of the catheter 10 in the receiving chamber 28. In a third embodiment the package 20 may be extruded in a tube shape and then the first longitudinal end 23 and second longitudinal end 24 sealed after insertion of the catheter 10 in the receiving chamber 28. As shown in FIG. 7B, the extruded shape may include longitudinal X creases to allow for flexibility of the package 20 during use.

[0057] As shown in FIGS. 1 and 6, the catheter 10 receiving chamber 28 extends from proximate the first longitudinal end 23 of the package 20 to proximate the second longitudinal end 24 of the package 20 as the first longitudinal end 23 and the second longitudinal end 24 are sealed after the catheter 10 is inserted in the receiving chamber 28. The receiving chamber 28 is sized, configured, and arranged to slideably engage the catheter 10.
Preferably, proximate the first longitudinal end 23 of the package 20 the size of the receiving chamber 28 is an inwardly directed shoulder 28b effective for decreasing the size of and constricting the receiving chamber 28 such that the shoulder 28b is sized, configured, Date recue / Date received 2021 -1 1-29 and arranged to prohibit movement of the proximal end 12 of the catheter 10 from exiting the receiving chamber 28 of the package 20.

[0058] Preferably, the package 20 has means to manually remove the first longitudinal end 23 and the second longitudinal end 24 to allow access to the catheter 10 receiving chamber 28. The ends 23 and 24 may have a line of weakness 29 such as perforations or score lines, a tear strip, or a point of weakness to allow easy opening of the package 20 without the need for scissors or a knife. Providing a line of weakness 29 may also direct the patient to open the package 20 at the proper place on the package 20 to allow the proximal end 12 of the catheter 10 to catch on the shoulder 28b of the receiving chamber 28.

[0059] As shown in FIGS. 2-4 and 9, the package 20 has a compact longitudinal length 22 that is shorter than the full longitudinal length 21 of the package 20.
Preferably the longitudinal length 13 of the catheter 10 is less than the longitudinal length 28a of the receiving chamber 28. If a non elastic catheter 10 is used this will allow the portion of the package 20 without the catheter 10 to be folded, bent or coiled to form the compacted package 20. It will also provide a longer receiving chamber 28 for use as a drainage tube during use of the catheter 10.

[0060] In the compact longitudinal length 22 the first longitudinal end 23 and the second longitudinal end 24 may be configured and arranged to be removed from the package 20 at the same time by aligning the removal means for each end as shown in FIGS. 3-4 and 9.
Preferably the longitudinal ends 23 and 24 are aligned and a fastener 50 used to attach the first end 23 to the second end 24 such that the patient can not remove the first longitudinal Date recue / Date received 2021 -1 1-29 end 23 without removing the second longitudinal end 24. The preferred fastener 50 is an adhesive.

[0061] The package 20 may be converted from the full longitudinal length 21 to the compacted length 22 by folding, coiling, bending, or pleating. As shown in FIGS. 2-4 and 10 the package 20 may be folded or bent a single time. The folding may be made easier by using a hinge 25, score line, or at least one set of laterally Y extending dimples 60 at the point of folding. The hinge 25 may be a live hinge 25 or a mechanical hinge 25. As shown in FIG. 8, the package 20 may be folded or bent more than one time to accommodate a package 20 with a longer full longitudinal length 21. This could allow for a longer drainage tube as well as to accommodate a longer catheter 10. As shown in FIG. 9, the package 20 may be coiled into the compact length 22. Again the package 20 may have one or more coils depending on the original full longitudinal length 21 of the package 20. As the package 20 is elastic, a fastener 50 may be needed to attach the first longitudinal end 23 of the package 20 to the second longitudinal end 24 to keep the package 20 in the compact position. Upon removing the longitudinal ends 23 and 24 of the package 20 or removing the fastener 50 from contact with one of the ends 23 and 24 of the package 20, the package 20 will return to the full longitudinal length 21.

[0062] As shown in FIG. 2 the package 20 may also have a mirror 40 on the outer surface 26b to aid the patient in inserting the catheter 10. The package 20 may have a minor like outer surface 26b to aid the patient in inserting the catheter 10.

[0063] The package 20 may also have a guide member 30 to aid the patient in removing the distal end 11 of the catheter 10 from the package 20 without touching the catheter 10 and Date recue / Date received 2021 -1 1-29 causing contamination. Preferably the guide member 30 has a tab 31 and a tether 32. As shown in FIG. 1, the tab 31, with one end (not numbered) of the tether 32, is attached to the first longitudinal end 23 of the package 20 and the other end (not numbered) of the tether 32 is attached to the distal end 11 of the catheter 10. As shown in FIGS. 1 and 6, the tab 31 may be embedded in the seal of the first longitudinal end 23 of the package 20 wherein removal of the first longitudinal end 23 from the package 20 removes the tab 31 allowing the distal end 11 of the catheter 10 to be pulled out of the package 20 with the tab 31.

[0064] Alternatively the proximal end 12 of the catheter 10 may be configured and arranged to allow the distal end 11 of the catheter 10 to be manually pushed out of the open longitudinal end of the package 20. As shown in FIGS. 1 and 11A-E, the proximal end 12 of the catheter 10 may be attached to or integrally formed with a push block 12a.
The push block 12a is shaped to allow a patient to easily grip the proximal end 12 of the catheter 10 through the package 20 and push the distal end 11 of the catheter 10 out of the opened first longitudinal end 23 of the package 20.

[0065] Use

[0066] The compact packaged intermittent urinary catheter 10 is used by patients for self catheterization. One or more of the compact packaged catheters 10 may be easily carried by a patient in a purse, bag or pocket. Prior to use the patient should take all sanitary procedures advised by their doctors to decrease the risks of infection from utilizing a catheter 10. The patient grasps the first and second longitudinal ends 23 and 24 of the compact elastic package and removes the ends 23 and 24. The ends 23 and 24 may be removed by cutting with a Date recue / Date received 2021 -1 1-29 knife or scissors, but preferably the ends 23 and 24 are removed manually along the lines of weakness 29 or at the point of weakness. As shown in FIGS. 5, 6, and 8, by removing the first longitudinal end 23 and the second longitudinal end 24 at the point of weakness or line of weakness 29, the package 20 will be open such that the receiving chamber 28 are now open. Removing the first longitudinal end 23 of the package 20 too far below the line of weakness 29 or the point of weakness could cause the package 20 to be opened such that the shoulder 28b of the receiving chamber 28 is also removed and proximal end 12 the catheter will no longer be captured within the package 20.

[0067] Upon removal of the first and second longitudinal ends 23 and 24 of the package 20, the package 20 is then returned to its full longitudinal length 21.

[0068] If the package 20 has a guide member 30, removal of the first longitudinal end 23 of the package 20 will allow the distal end 11 of the catheter 10 to slide from the package 20 without the need to touch or contaminate the catheter 10. If the proximal end 12 of the catheter 10 remains in the receiving chamber 28 of the package 20, the package 20 can be used as a drainage tube for the catheter 10. The catheter 10 is then inserted into the urethra of the patient. As the urine travels through the catheter 10 and exits the proximal end 12 of the catheter 10, it enters the receiving chamber 28 of the package 20 and travels through the longitudinal length 28a of the chamber 28 and out the now open second longitudinal end 24 of the package 20 and into a waste receptacle.

[0069] If the catheter 10 has a push block 12a proximate the proximal end 12 of the catheter 10, after the package 20 is opened and the package 20 returns to the full longitudinal length 21, the patient grasps the push block 12a at the proximal end 12 of the catheter 10 Date recue / Date received 2021 -1 1-29 through the package 20 and pushes the distal end 11 of the catheter 10 out of the package 20 without touching or contaminating the catheter 10. The catheter 10 may then be used the same as the catheter 10 with the guide member 30.

[0070] After the bladder is emptied, the catheter 10 is removed from the urethra and the catheter 10 can be pushed back into the package 20 for easy and mess free disposal.

[0071] The compact package described herein may be used to store a sterile catheter packed therein or may be provided along with or separately from the catheter.
In either case, the package is preferably used as an aid for inserting the catheter into the urethra. The embodiments described above include the catheter stored in the package which also contains lubricant to assist urethral insertion, or the catheter may be separately inserted into the lubricant-filled package at the time of usage. It should be noted that all of the variations described above pertaining to the way the package is held in a compact shape, or which assist in opening the package to its elongated shape apply equally to the separate package described below. Likewise, other constructional aspects such as materials and dimensions described above may apply equally to the stand-alone package described below.

[0072] FIG. 14 is a front perspective view of an alternative form of a package 80 for assisting insertion of an intermittent urinary catheter shown in compact longitudinal length, while FIG. 14A is a cross-sectional side view of the package 80 taken along line 14-14.

[0073] The package 80 has a first longitudinal end 82 and a second longitudinal end 84 and defines an elongate catheter receiving chamber 86 extending along a portion of the full longitudinal length of the package 80. As shown in FIG. 14, a first embodiment of the Date recue / Date received 2021 -1 1-29 package 80 may be constructed from a base sheet of material and cover sheet of material sealed along side edges 88a and end edge 88b to form the catheter receiving chamber 86 therein. The elongated package 80, best seen in partial view in FIG. 16, folds at a mid-point 90 so that the first and second longitudinal ends 82, 84 meet and are joined into the single end edge 88b. The first longitudinal end 82 and the second longitudinal end 84 are sealed after addition of a lubricating medium in the receiving chamber 86. In a second embodiment the package 80 may be extruded in a tube shape and then the first longitudinal end 82 and second longitudinal end 84 sealed after addition of a lubricating medium in the receiving chamber 86, as in shown in FIG. 7B. A third embodiment of the package 80 may also be constructed from a single base material folded upon it to provide a single sealed edge, as in FIG. 7C.

[0074] FIG. 14 also shows a score or notch 92 formed at an outer extent of the sealed side edges 88a at a longitudinal location below the end edge 88b and aligned with the inner chamber 86. An upper portion of the compacted package may be cut away or torn off using the notch 92 as a starter, as seen in FIG. 15, to expose the inner chamber 86 by removing both the first and second longitudinal ends 82, 84. FIG. 16 is a perspective view of the package 80 after removal of the first and second longitudinal ends 82, 84 and in full longitudinal length from a first open end 94 to a second open end 96.
Indicator arrows 98 are desirably printed on one or both exterior sides of the elongated package 80 oriented in one longitudinal direction.

[0075] FIG. 17 is a perspective view of the elongated package 80 showing a user inserting an intermittent urinary catheter 100 therein in the direction of the indicator arrows Date recue / Date received 2021 -1 1-29 98. The catheter may be any of the various embodiments described above, or other types. A
leading end of the catheter is inserted into the first open end 94 and pushed through the chamber 86 having lubricating medium therein.

[0076] FIG. 18 shows the intermittent urinary catheter 100 passing completely through the elongated package 80, emerging from the second open end 96. A lubricating medium 102 is seen adhered to an outer surface of the catheter 100 from passing through the catheter-receiving chamber 86.

[0077] The package 80 is then used to assist in inserting the catheter 100 into a urethra.
FIG. 19 is a perspective view like FIG. 18 showing the user holding the package 80 with the intermittent urinary catheter 100 therein in preparation for use. A portion of the leading end 104 of the catheter 100 with lubricant 102 thereon extends from the second open end 96. The user can easily and cleanly grasp the side of the elongated package 80 to manipulate the leading end 104 into the proper position. Once the leading end 104 is inserted into the urethra, the user can maintain a grip on the catheter 100 as it is advanced in stages, with the package 80 sliding back over the catheter so as to continue to lubricate its length. When the process is complete, the package 80 again can be used to grip and remove the catheter 100 from the urethra.

[0078] The stand-alone package 80 described above is easy and convenient to use with a variety of different catheters. Often, with simple ketchup-style gel packages used to deposit lubricant on the catheter the gel coating can be lumpy and inconsistent. With the catheter 100 passing through the package chamber 86, the gel is instead applied evenly and smoothly. Further, the user's fingers remain outside the package 80 at all times so there is no mess. The Date recue / Date received 2021 -1 1-29 package 80 acts as a clean handling sleeve for both advancing and retracting the catheter. The package 80 is relatively simple and economical, making it an advantageous way to facilitate the often messy job of urinary catheter insertion.
