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.
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.
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.
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.
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.
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 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.
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.
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.
A method of using an intermittent urinary catheter is also described including the steps of:
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.

Construction
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.
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.
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.
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
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.
Preferably the catheter 10 is packaged in an elastic package 20. As shown in
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.
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
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.
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 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
As shown in
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.
As shown in
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
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
As shown in
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 causing contamination. Preferably the guide member 30 has a tab 31 and a tether 32. As shown in
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
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 20 and removes the ends 23 and 24. The ends 23 and 24 may be removed by cutting with a 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
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.
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.
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 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.
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.
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.
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
The package 80 is then used to assist in inserting the catheter 100 into a urethra.
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 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.
Throughout this description, the embodiments and examples shown should be considered as exemplars, rather than limitations on the apparatus and procedures disclosed or claimed. Although many of the examples presented herein involve specific combinations of method acts or system elements, it should be understood that those acts and those elements may be combined in other ways to accomplish the same objectives. Acts, elements and features discussed only in connection with one embodiment are not intended to be excluded from a similar role in other embodiments.
