Description

Attorney Docket No.3400-0305.01 (806PCT) Hydrophobic Collection Bag The present application claims the benefit of and priority to U.S. Provisional Application 63 / 623,092, filed January 19, 2024, which is hereby incorporated herein by reference. FIELD OF THE INVENTION

[0001] This disclosure generally relates to a hydrophobic collection bag. More particularly, this disclosure relates to a urinary catheter product associated with a hydrophobic urine collection bag. BACKGROUND

[0002] Patients with spinal cord injuries (SCI) or other neurogenic bladder conditions typically need to empty their bladders by urinary catheterization. In some instances, intermittent catheterization is a good option for many users who suffer from various abnormalities of the urinary system. With the advent of intermittent urinary catheters, individuals with problems associated with the urinary system can conveniently self-catheterize to drain the individual’s bladder. In other instances, a patient may not be able to self-catheterize, and may need a medical professional to insert an indwelling catheter. Additionally, a catheter may be used to facilitate drainage of urine from the urinary bladder by interfacing via the urethra or other means of access, such as diversion or a Mitrofanoff procedure.

[0003] A urinary catheter may be associated with a collection bag. Urine evacuated from a bladder may be collected into the collection bag. After collection, the bag may be emptied into a receptacle, such as a toilet, and the bag can be disposed of. When the user is not near a suitable receptacle, the user may seal and store the collection bag until its contents and the bag may be properlyAttorney Docket No.3400-0305.01 (806PCT) disposed of. Additionally, in some instances, the collection bag can be cleaned, sterilized, and reused.

[0004] After emptying the collection bag of its contents, some residual urine may still be present inside the collection bag. Additionally, drips of urine may get on the outside of the bag during and after draining it. Residual urine present on the inside or outside of the bag may promote the growth of microbes and bacteria, create an unsanitary environment, and may make the bag difficult to handle during drainage, disposal, or reuse of the bag.

[0005] Therefore, there is a need for improved urine collection bags and catheterization devices, products, and assemblies including the same. SUMMARY OF INVENTION

[0019] A more detailed description of the device in accordance with the present disclosure is set forth below. It should be understood that the description of the specific devices below is intended to be exemplary, and not exhaustive of all possible variations or applications. Thus, the scope of the disclosure is not intended to be limiting and should be understood to encompass variations or embodiments that would occur to persons of ordinary skill.

[0020] FIG. 1 shows an example of a urinary catheter product 10, such as an intermittent urinary catheter product. The urinary catheter product 10 includes a fluid collection bag 12 (such as a urine collection bag) and a urinary catheter 14 associated with the fluid collection bag 12. The urinary catheter 14 can be pre- attached to the collection bag 12 or the urinary catheter 14 can be coupled to the collection bag 12 prior to use. For example, a user may couple the urinary catheter 14 and collection bag 12 together before use. The urinary catheter product 10 is configured to facilitate drainage of urine from a patient’s bladder. For example, the urinary catheter product 10 can be configured to drain urine by interfacing via the urethra using an intermittent or indwelling (i.e., Foley) catheter. Alternatively, the urinary catheter product 10 can be configured to access the bladder via diversion or a Mitrofanoff procedure.

[0021] As shown in FIG. 1, urinary catheter 14 is illustrated as an intermittent urinary catheter, although other catheters may be used without departing from the scope of the disclosure. Urinary catheter 14 includes a catheter tube 16 having a catheter tube proximal insertion end 18 and a catheter tube distal drainage end 20. The tube defines a lumen extending from the catheter tube proximal insertion end 18 to the catheter tube distal drainage end 20.Attorney Docket No.3400-0305.01 (806PCT)

[0022] The catheter tube proximal insertion end 18 includes at least one opening (not shown) for receiving urine in communication with the lumen. In one embodiment, the opening for receiving urine may be an eyelet. In another embodiment, the opening for receiving urine may be multiple eyelets. The opening for receiving urine may vary in shape, size, and location without departing from the scope of the disclosure.

[0023] Additionally, the catheter tube 16 may include a hydrophilic polymer coating on the tube's outer surface. The hydrophilic polymer coating may be configured to absorb a hydration medium to lubricate the catheter for easing insertion into a urethra. In other embodiments, the catheter tube 16 may be lubricated with a gel-lubricant.

[0024] Furthermore, the catheter tube distal drainage end 20 includes a drainage opening for draining urine from the lumen. In one embodiment, the catheter tube distal drainage end 20 includes a drainage member 22. The drainage member 22 may be attached to the catheter tube distal drainage end 20 and may be in fluid communication with the drainage opening. The drainage member 22 may be, for example, but not limited to, a funnel or connector for connection to the fluid collection bag 12. Other suitable drainage members may be used without departing from the scope of the disclosure.

[0025] Referring to FIG. 2, the fluid collection bag 12 is formed of at least one polymer sheet or film 24 defining a wall with a polymer sheet first side 26 and a polymer sheet second side 28. FIG.2 shows an example of a polymer sheet 24 that may be used to form fluid collection bag 12. The polymer sheet 24 can include polypropylene, polyethylene, polytetrafluoroethylene (PTFE), and / or polyvinyl chloride (PVC). Other suitable polymers can be used to create theAttorney Docket No.3400-0305.01 (806PCT) polymer sheet 24 without departing from the scope of the disclosure. The polymer sheet 24 can include at least one hydrophobic surface 30. For instance, at least one of the polymer sheet first side 26 and the polymer sheet second side 28 can include a hydrophobic surface 30. In an example, as shown in FIG. 2, both the polymer sheet first side 26 and the polymer sheet second side 28 include a hydrophobic surface 30.

[0026] The hydrophobic surface 30 can include a hydrophobic layer. In an example, the hydrophobic layer 30 includes a treatment including a hydrophobic compound. For instance, the polymer sheet first side 26 and / or the polymer sheet second side 28 may be treated with a hydrophobic compound to create a hydrophobic layer 30.

[0027] In particular, hydrophobic layer 30 can be created using treatments such as chemical grafting, surface etching followed by hydrophobic compound deposition, physical vapor deposition (PVD), chemical vapor deposition (CVD), and / or dip coating. In an example, the polymer sheet first side 26 and / or the polymer sheet second side 28 can be treated using these methods with a hydrophobic compound to create hydrophobic layer 30. In another example, layer- by-layer assembly or electrospinning can also be employed to create hydrophobic layer 30.

[0028] The hydrophobic compound can include fluorinated hydrocarbons, siloxanes, long chain hydrocarbons, perfluorinated compounds, waxes, fatty acids, and paraffin. Other specialized compounds, such as hydrophobic nano- particles like silica or titanium dioxide, may also be utilized. In some examples, a combination of hydrophobic compounds can be used to treat the first side 26 and / or second side 28 to create hydrophobic layer 30. Other suitable hydrophobicAttorney Docket No.3400-0305.01 (806PCT) compounds and treatment techniques may be used without departing from the scope of the disclosure.

[0029] In another example, the hydrophobic layer 30 includes a hydrophobic coating. The coating can include, but is not limited to, fluoropolymers such as polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF), silicone polymers such as polydimethylsiloxane (PDMS), and / or hydrophobic nanocomposite coatings that may contain hydrophobic nanoparticles such as silica, titanium dioxide, or graphene. Additionally, the coating can include materials like perfluorinated coatings, wax-based coatings, and / or hydrophobic acrylate or methacrylate coatings. Other suitable hydrophobic coatings may be used without departing from the scope of the disclosure.

[0030] The hydrophobic coating may be applied to the polymer sheet 24 by, but not limited to, spray coating, dip coating, chemical vapor deposition, roll-to-roll processing, brush coating, spin coating, or by any other suitable coating techniques.

[0031] Alternatively, a hydrophobic property can be imparted to the polymer sheet first side 26 and / or the polymer sheet second side 28 to obtain a hydrophobic surface. For example, the polymer sheet first side 26 and / or polymer sheet second side 28 can include a micro- or nano-patterned structure that creates a hydrophobic property. Accordingly, when the collection bag 12 is formed of a polymer sheet including micro- or nano-patterned structures, the micro- or nano-patterned structures can reduce any wetness on the outside surface of the bag by sloughing off any fluid. Additionally, the micro- or nano-patterned structure also increases efficient flow of fluid into and out of the collection bag 12.

[0032] In an example, the micro- or nano-patterned structure may include aAttorney Docket No.3400-0305.01 (806PCT) “lotus leaf” structure 60, as shown in FIG.8. In another example, as shown in FIG. 9, the micro- or nano-patterned structure may be a water strider leg structure 70, which resembles the structure of a water strider’s leg. The water strider leg structure 70 includes a bump 72, setae 74, and nanogrooves 76 associated with the surface of the setae. Similar to the leg of a water strider, bump 72 can be cylindrical or semi-cylindrical shape from which at least one seta may extend. Bump 72 can be formed or attached to the side 26 and / or 28 of the polymer sheet 24. The radius of the bump 72 can be about 40 μm, but can vary in size without departing from the scope of the disclosure. Polymer sheet 24 can include one or more bumps located on side 26 and / or 28. Setae 74 extend from bump 72 at an angle. For instance, the setae 74 may extend from the bump 72 at about a 60° angle. Additionally, the setae 74 can be about 600 μm long and include a tapered width. In an example, the setae 74 include a diameter of about 10 μm at the bump 72 and a diameter of about 2 μm at the opposite tip. Furthermore, the setae 74 include a longitudinal, helicoidal or quasi-helicoidal nanogroove 76. The nanogroove 76 can include a width of about 200 nm, a depth of about 100 nm, and a pitch of about 1 μm. The dimensions of the components of the water strider leg structure 70 can vary without departing from the scope of the disclosure. Similar to a water strider’s leg in nature, the water strider leg structure 70 enhances the hydrophobicity of the sides 26 and / or 28 of polymer sheet 24 by repelling water droplets.

[0033] The micro- or nano-patterned structure can be created by etching, lithography, template-assisted synthesis, and / or by a self-assembly process. Other suitable methods of creating a patterned structure may be used without departing from the scope of the disclosure.Attorney Docket No.3400-0305.01 (806PCT)

[0034] The polymer sheet first side 26 and the polymer sheet second side 28 can include a hydrophobic surface formed by any or a combination of methods as described herein. For instance, both of the polymer sheet first side 26 and the polymer sheet second side 28 can include a hydrophobic surface formed in the same manner, or the polymer sheet first side 26 and the polymer sheet second side 28 can include a hydrophobic surface formed in a different manner from one another.

[0035] As shown in FIG. 3, the collection bag 12 can be formed of at least one polymer sheet 24. For example, the polymer sheet 24 can be folded and sealed to itself at a first peripheral side 32, at a second peripheral side 34, and at a top side 36. The terms peripheral and top are used herein as exemplary terms to describe the three sides of the folded polymer sheet excluding the folded side 31 and are not meant to be limiting. The sides can be sealed together by heat sealing, welding, adhesion, or any other suitable method of sealing. The polymer sheet can be folded such that one of the polymer sheet first side 26 or polymer sheet second side 28 defines an inner surface of the collection bag 12 and the other of the first side or second side defines an outer surface of the collection bag 12. Accordingly, the inner surface defines a chamber 41. The chamber 41 is configured to receive at least a drained fluid, such as urine from a user’s bladder.

[0036] In another embodiment, as shown in FIG. 1, the collection bag 12 can be formed of two polymer sheets 24. The polymer sheets 24 can be any of the polymer sheets described herein. The collection bag 12 can be formed by sealing two polymer sheets 24 to one another along their perimeters. In other words, collection bag 12 can be sealed at a first peripheral side 32, at a second peripheral side 34, at a top side 36, and at a bottom side 38. In particular, theAttorney Docket No.3400-0305.01 (806PCT) sheets may be arranged and sealed together such that the collection bag 12 includes a hydrophobic inner surface and / or a hydrophobic outer surface. The sheets 24 can be sealed together using any of the sealing methods described herein. The inner surface defines a chamber 41 configured to receive at least a drained fluid, such as urine from a user’s bladder.

[0037] The size and shape of the collection bag 12 can vary without departing from the scope of the disclosure.

[0038] By including a hydrophobic surface 30 on the polymer sheet(s) 24, when emptying the collection bag 12, the collection bag 12 is configured to be fully emptied without residual urine being left inside. Additionally, if the outer surface of collection bag 12 includes a hydrophobic surface 30, any drips of urine or other fluid may be easily removed and the bag can be handled, disposed of, or reused (after cleaning and sterilization) in a more sanitary manner. The hydrophobic surfaces 30 also reduce the adhesion of urinary components to the collection bag 12. Accordingly, the hydrophobic surfaces 30 prevent microbe adhesion and growth and / or can be self-cleaning. Furthermore, a hydrophobic inner surface also minimizes backflow of urine within the collection bag 12 into the urinary catheter 14 and therefore, prevents risks associated with backflow.

[0039] As disclosed herein, urinary catheter product 10 includes a collection bag 12 associated with a urinary catheter 14. In an example, the urinary catheter 14 can be pre-attached to the collection bag 12. In this instance, as best shown in FIGS.1 and 6, at least a portion of catheter tube 16 can be located within fluid collection bag 12. For example, when in a stored configuration, a portion of the catheter tube 16, including the catheter tube distal drainage end 20 and drainage member 22, are located within the collection bag 12. The catheter tube proximalAttorney Docket No.3400-0305.01 (806PCT) insertion end 18 can be located outside of the collection bag 12.

[0040] Alternatively, urinary catheter 14 can be coupled to the collection bag 12 prior to use. In particular, urinary catheter 14 can be attached to the collection bag 12 via the drainage member 22. In an embodiment, drainage member 22 can be attached to a port included on the collection bag 12. In another embodiment, catheter tube distal drainage end 20 can be sealed between the walls of collection bag 12.

[0041] The urinary catheter product 10 can also include additional features configured to assist in storage and / or use of the urinary catheter product 10.

[0042] For example, the collection bag 12 can include an introducing aid 40, as shown in FIG. 1. Introducing aid 40 can be used to assist with insertion of the urinary catheter 14 into the urethra. The introducing aid 40 includes a proximal insertion tip 42 and a distal gripping portion 44. In some embodiments, introducing aid 40 can also include an intermediate flange 46. The introducing aid 40 can be attached to the collection bag 12, for instance, by sealing the distal gripping portion 44 between the walls of the collection bag 12.

[0043] The proximal insertion tip 42 is configured to be openable. For example, the proximal insertion tip 42 can be opened by advancing the catheter tube 16 therethrough. In an embodiment, the proximal insertion tip 42 is defined by one or more slits between one or more flexible petals. The petals may move, bend, and or resiliently deform from the generally closed configuration to an open configuration when a catheter tube 16 is advanced therethrough. In another embodiment, the insertion tip 42 may include a rupturable proximal end.

[0044] The intermediate flange 46 may contact the user around the urethral opening and act as a stop to limit the insertion of the insertion tip 42 into theAttorney Docket No.3400-0305.01 (806PCT) urethra. The flange 46 may also aid in placement of the user’s fingers on the gripping portion 44.

[0045] Optionally, as shown in FIGS. 4-6, the catheter product 10 can include a cap 48 configured to cover the introducing aid 40. The cap 48 can be attached to the introducing aid 40 via, for example, but not limited to, a friction fit. For example, the cap 48 can be attached to the intermediate flange 46. The cap 48 is configured to prevent contamination of the introducing aid 40 when the catheter product 10 is in storage.

[0046] Additionally, the fluid collection bag 12 can include a tear strip to assist the user in opening the collection bag to empty it of any collected fluid. The tear strip can include a tear starter in one of the peripheral sides 32 or 34, a weakened portion of the polymer sheet 24, and / or a perforation. Alternatively, the fluid collection bag 12 can include a resealable opening configured to drain the collection bag of its contents. For instance, the resealable opening could be a port configured to receive an attachable catheter or it could be a separate resealable opening configured to drain contents within the collection bag 12. The resealable opening can be sealed when the collection bag 12 is in a stored configuration before use or after collection of any fluid from a user. The resealable opening can be placed in an open configuration when the collection bag 12 is to be emptied of its contents.

[0047] The collection bag 12 can also include various designs / artwork on its outer surface. For instance, one side of the bag can include artwork and the other side can be transparent with volume indicators.

[0048] Furthermore, collection bag 12 can include at least one hole 50, such as a finger hole, configured to assist a user in handling the collection bag 12. ForAttorney Docket No.3400-0305.01 (806PCT) example, FIG.6 shows a collection bag with a hole 50 located near a top corner of the collection bag 12. In some embodiments, the collection bag can include two holes 50, as shown in FIGS. 4 and 7. The holes 50 can be located near opposite corners on the same peripheral side (32 or 34). Optionally, the holes 50 can be located on a side opposite a tear strip or resealable opening (if present). As shown in FIG. 7, if two holes 50 are included, a user may tear open the collection bag 12 and grip the bag via the two holes 50 to better handle and tilt the bag to empty it of its contents.

[0049] Furthermore, the collection bag 12 can include an attachment element 52 configured to retain the collection bag 12 in a folded configuration for storage, as shown in FIGS. 4-5. For example, a portion of the outer surface of the collection bag 12 can include an adhesive element such as tape, glue, tack, or any other suitable adhesive element. In another example, a top portion and bottom portion of the outer surface of the collection bag 12 can include complementary attachment elements, for example, but not limited to, hook-and- loop elements.

[0050] To use the catheter product 10, a user may unfold the collection bag 12 and remove the cap 48 from the introducing aid 40 (if present). The user may then grasp the gripping portion 44 of the introducing aid 40 and insert the insertion tip 42 into the urethra. The user can then grasp the catheter tube 16 through the collection bag 12 and advance the catheter tube 16 through the introducing aid 40 and into and through the urethra until the at least one opening enters the bladder. Once the at least one opening of the catheter tube 16 enters the bladder, urine can drain into collection bag 12. After the bladder has been evacuated of urine, the user may remove the catheter tube 16 from the urethra. If the collection bagAttorney Docket No.3400-0305.01 (806PCT) 12 is to be emptied, the user can then open the collection bag 12. The user can use the holes 50 (if present) to handle the collection bag 12, and empty the bag 12 into a receptacle such as a toilet. After emptying the collection bag 12, the collection bag 12 may be disposed of in a suitable container such as trash bin. In an embodiment, if the collection bag 12 is resealable, after emptying it of its contents, the collection bag 12 can be cleaned and / or sanitized to be reused.

[0051] Alternatively, if the catheter product 10 does not include a urinary catheter 14 pre-attached to the collection bag 12, a user can first attach a urinary catheter 14 to the collection bag 12 before inserting it into the urethra. After attaching the urinary catheter 14 to the collection bag 12, the catheter tube 16 can be advanced through the urethra until the at least one opening enters the bladder. Once the at least one opening of the catheter tube enters the bladder, urine can drain into collection bag 12. After the bladder has been evacuated of urine, the user can remove the catheter tube 16 from the urethra. If the collection bag 12 is to be emptied, the user can then open the collection bag 12. The user can use the holes 50 (if present) to handle the collection bag 12, and empty the bag into a receptacle such as a toilet. After emptying the collection bag 12, the collection bag 12 may be disposed of in a suitable container such as trash bin. In an embodiment, if the collection bag 12 is resealable, after emptying it of its contents, the collection bag 12 can be cleaned and / or sanitized to be reused.

[0052] It will be understood that the embodiments and examples described above are illustrative of some of the applications of the principles of the present subject matter. Numerous modifications may be made by those skilled in the art without departing from the spirit and scope of the claimed subject matter, including those combinations of features that are individually disclosed or claimed herein.Attorney Docket No.3400-0305.01 (806PCT) For these reasons, the scope hereof is not limited to the above description but is as set forth in the following claims, and it is understood that claims may be directed to the features hereof, including as combinations of features that are individually disclosed or claimed herein.
