Description
BACKGROUND OF THE INVENTION

Persons experiencing an inability to control the passage of urine ranging from an occasional leakage of urine, to a complete inability to hold any urine have need for a urinary control device that will not leak and is simple to install, operate and remove.


Incontinence is a problem for many people including older adults. Present day approaches for dealing with incontinence such as the Foley catheter often times cause urinary tract infections. A bag for urine is required and smell becomes a problem. The chances of infection are increased each time the bag is changed. The cost for the Foley catheters and bags is substantial. An inflatable conventional spherical balloon is used to keep the catheter in the bladder, but leakage around the catheter occurs and is a problem. It was not an object of this product to provide a seal around the catheter at the bladder orifice.


What is needed is a simple inexpensive device for controlling urine flow through the urethra which is compatible to the body and will not cause discomfort, infection and pass urine but only by operation of the valve rather than around the outside of the catheter.

DETAILED DESCRIPTION OF THE DRAWINGS

The present invention includes a number of aspects all of which have broad and far reaching applications. Although specific embodiments are described herein, the present invention is not limited to the specific embodiments. One aspect of the invention relates to the use of an expandable membrane for sealing off at the neck and along the inside wall of the bladder. The expandable membrane is deployable using balloons and other devices for erecting and shaping the expandable membrane into a sealing position. The invention includes also a coupling member with a balloon valve for selectively passing urine from the bladder.


Turning now to the drawings in which similar reference characters denote similar elements through the several views. Illustrated in FIGS. 1-13 is the combination of various views and in use configurations of a urinary incontinence and coupling device.



FIG. 1 is a front view of one embodiment of the control device. In FIG. 1, the urinary control device is shown having a tubular member 18. The tubular member 18 has inner 25 and outer 23 ends interconnected by a passageway 26. The tubular member 18 also has a sidewall 20 with inner 24 and outer 22 surfaces. The passageway 26 within tubular member 18 is defined by the inner 24 sidewall surface. Also shown is an inflatable balloon 30 having a central passageway 32. The central passageway 32 in the inflatable balloon 30 surrounds the outer 22 sidewall 20 surface of the tubular member 18. Also shown is an expandable outermost tubular member 34 covering the inflatable balloon 30 and attached to the outer surface 22 of the tubular member 18. The expandable outermost tubular member 34 has a first end 36 and a second opposite end 38 that are fixedly attached to the outer 22 sidewall 20 surface of the tubular member 18. Shown on the expandable outermost tubular member 34 is an annular thinned wall portion 40 positioned between the first 36 and second 38 opposite end on the outermost tubular member 34. The annular thinned wall portion is preferably 1-2 mm across, as best shown in FIG. 1A, to encourage deformation and expansion of the outermost tubular member 34 along the annular thinned wall portion 40. The annular thinned wall portion 40 on the outermost tubular member 34 is operational between a collapsed shape 42 being coaxial with the tubular member 18 and an expanded shape 44 forming a seal 46 between the expandable outermost tubular member 34 and the neck 12 and inner wall 14 of the bladder 16. Before the urinary control device 10 is inserted, the inner tubular member 18 is measured and cut to the length of the urethra 15. A coupling member 70 is inserted into the outer end 23 of the inner tubular member 18. The coupling member 70 has a passageway 72 with an inner sidewall surface 74 for passing urine there-through. The coupling member 70 also has an inflatable balloon valve 76 positioned within the passageway 72 of the coupling member 70 for selectively passing urine there-through. The inflatable balloon valve 76 is attached about the entire circumference 78 of the inner sidewall surface 74 of the passageway 72. When the inflated balloon valve 76 is in the normally closed inflated 80 position, the inflatable balloon valve 76 is expanded radially inward away from the inner surface 74 of the passageway 72 toward the center 82 of the passageway 70 in sealing engagement with itself. The inflatable balloon valve 76 in the inflated position 80 prevents urine from passing through the passageway 72 from within the bladder 16.


A pump 84, as shown, is used to inflate and deflate the inflatable balloon valve 76 for selectively passing urine through the passageway 72 from the bladder 16. The inflatable balloon valve 76 is by default kept in the normally closed inflated condition 80.


The inflatable balloon 30 is expanded after the device 10 is inserted. To inflate the inflatable balloon 30 an inflation conduit 28 extends between the inflatable balloon 30 and the outer ends 23 of the inner tubular member 18. The coupling member 70 contains a coupling 27 for connecting the inflation conduit 28 in the inner tubular member 18 to the inflation conduit 28 in the coupling member 70. As part of the coupling member 70, a check valve 79 is connected to the inflation conduit 28 thereby providing fluid communication to the inflatable balloon 30. Thus, by use of a syringe or any other injectable means, saline is injected through the insert 83 in the check valve 79 and inflation conduit 28 to inflate the inflatable balloon 30.



FIG. 3 is a cross sectional of one embodiment of the control device positioned in a bladder with an outer member having been partially expanded. In FIG. 3, the inflatable balloon 30 is partially inflated. The inflatable balloon 30 is positioned and expanded between the inner 18 and outermost tubular member 34. The inflatable balloon 30 is attached to the outer sidewall 22 of the inner tubular member 18. Thus, as the inflatable balloon is inflated the annular thinned wall portion 40 on the outermost tubular member 34 encourages expansion of the outermost tubular member 34 along the annular thinned wall portion 40 radially outward and away from the outer sidewall 22 of the inner tubular member 18. As the annular thinned wall portion 40 expands radially outward slack in the outermost tubular member 34 between the first 36 and second end 38 is taken up in the outward expansion of the outermost tubular member along the annular thinned wall portion 34. The annular thinned portion 40 expands with the inflatable balloon 30 away from the outer sidewall 22 of the inner tubular member 18 to seal against the neck 12 and inner wall 14 of the bladder 16. The annular thinned wall portion 40, along with the outermost tubular member 34 having slack in the member 34 between the first 36 and second opposite end 38, allows the outermost tubular member 34 to expand to accommodate retention and sealing in larger diameter urethras.



FIG. 4 is cross sectional view of one embodiment of the control device positioned in a bladder with the outer member having been fully expanded. In FIG. 4, the inflatable balloon 30 has been expanded to the position where the annular thinned wall portion 40 on the outermost tubular member 34 creates a seal 46 between the outermost tubular member 34 and the neck 12 and inner wall 14 of the bladder 16.



FIG. 5 is a front view of another embodiment of the control device. In FIG. 4, the slack between opposite ends 36, 38 in the outermost tubular member 34 has been taken up in the expansion of the inflatable balloon 30.



FIG. 5 is a front view of another embodiment of the control device. In FIG. 5, the expandable sealing member is shown as an umbrella shaped member 48 and the deployable stiffening member is shown as an inflatable umbrella shaped balloon 50 formed within and by the umbrella shaped member 48. The proximal end 54 of the umbrella shaped member 48 is fixedly attached to the outer 22 sidewall 20 of the inner tubular member 18. The expandable perimeter on the umbrella shaped member 48 are free outer ends 52 opposite the proximal ends 54. The inflatable umbrella shaped balloon 50 within the umbrella shaped member 48 is operational between inflated 56 and deflated 58 conditions. When inflated, the inflatable umbrella shaped balloon 50 erects and shapes the umbrella shaped member 48 and seats the outer surface 60 of the umbrella shaped member 48 against the inside wall 14 and neck 12 of bladder 16 to prevent leaking. In addition, for insertion of the device 10 a dissolvable gel cap 49 is used to encapsulate the outer surface 60 of the umbrella shaped member 48, as illustrated in FIGS. 5 and 6. To inflate the inflatable umbrella shaped balloon 50 an inflation conduit 19 extends between the inflatable umbrella shaped balloon 50 and the outer end 23 of the inner tubular member 18. The coupling member 70 contains a coupling 27 for connecting the inflation conduit 19 in the inner tubular member 18 to the inflation conduit 28 in the coupling member 70. As part of the coupling member 70, a check valve 79 is connected to the inflation conduit 28 thereby providing fluid communication to the inflatable umbrella shaped balloon 50. Thus, by use of a syringe or any other injectable means, saline is injected through the insert 83 in the check valve 79 and through inflation conduits 28 and 19 to inflate the inflatable umbrella shaped balloon 50. The coupling member 70 also includes a passageway 72 with an inner sidewall surface 74 for passing urine there-through. The coupling member 70 also has an inflatable balloon valve 76 positioned within the passageway 72 of the coupling member 70 for selectively passing urine there-through. The inflatable balloon valve 76 is attached about the entire circumference 78 of the inner sidewall surface 74 of the passageway 72. When the inflated balloon valve 76 is in the normally closed inflated 80 position, the inflatable balloon valve 76 is expanded radially inward away from the inner surface 74 of the passageway 72 toward the center 82 of the passageway 70 in sealing engagement with itself. The inflatable balloon valve 76 in the inflated position 80 prevents urine from passing through the passageway 72 from within the bladder 16.


A second inflatable balloon 64 is positioned at the inner end 25 and around the outer sidewall 22 of the inner tubular member 18 for operation between inflated 66 and deflated 68 conditions. As best illustrated by FIG. 7, the second inflatable balloon 64 when inflated 66 presses against the inner surface 62 of the umbrella shaped member 48 to help retain the device 10 within the bladder 16 thereby maintaining sealing engagement between the outer surface 60 of the umbrella shaped member 48 and the inside wall 14 and the neck 12 of the bladder 16 to prevent leaking. To expand or inflate the second inflatable balloon 64 a second inflation conduit 21 extends between the second inflatable balloon 64 and the outer end 23 of the inner tubular member 18. A coupling member 70 is inserted into the outer end 23 of the inner tubular member 18 after the inner tubular member 18 is measured and cut to the length of the urethra 15. The second inflatable balloon 64 is inflated 66 using the second inflation conduit 21. The coupling member 70 contains a coupling 27 for connecting the second inflation conduit 21 in the inner tubular member 18 to the inflation conduit 28 in the coupling member 70. As part of the coupling member 70, a check valve 79 is connected to the inflation conduit 28 thereby providing fluid communication to the second inflatable balloon 64. Thus, by use of a syringe or any other injectable means, saline is injected through the insert 83 in the check valve 79 and through the inflation conduits 28 and 21 to inflate the inflatable balloon 30. The coupling member 70 is used to selectively pass urine through the passageway 72 of the coupling member 70. After the device 10 is inserted and the gel cap 49 dissolves the inflatable umbrella shaped balloon 50 is inflated using the inflation conduit 19. During inflation of the inflatable umbrella shaped balloon 50 the free outer ends 52 of the umbrella shaped member 48 expand radially outward from the collapsed closed shape 58 thereby sealing the outer surface 60 of the umbrella shaped member 48 against the inside wall 14 and the neck 12 of the bladder 16 to prevent leaking. The second inflatable balloon 64 is also expanded and presses against the inner surface 62 of the umbrella shaped member 48 to help retain the device 10 within the bladder 16.



FIG. 8 is a front view of an additional embodiment of the control device. In FIG. 8, the expandable ceiling member is an umbrella shaped member 48 and the deployable stiffening member 50 is a wire frame 86 positioned within the umbrella shaped member 48. The umbrella shaped 48 is attached at its proximal end 54 to the outer 22 sidewall 20 of the inner tubular member 18. Opposite the proximal ends 54 are free outer ends 52 on the umbrella shape 48. The wire frame 86 positioned within the umbrella shaped member 48 is operational between collapsed 90 and expanded 88 conditions. The normally open wire frame 86 within the umbrella shaped member 48 is encapsulated using the gel cap 49 in the collapsed condition 90. Thus, after insertion, the gel cap 49 dissolves (See FIG. 9) and the wire frame 86 expands to its normally open position 88 thereby erecting and shaping the umbrella shaped member 48 to seat the outer surface 60 of the umbrella shaped member 48 against the inside wall 14 and neck 12 of the bladder 16, as best illustrated by FIG. 10.



FIG. 11 is a top plane view of the wire frame 86 within the umbrella shaped member 48 and in the expanded position 88. The wire frame 86 within the umbrella shaped member 48 is a continuous wire frame that is by default in the expanded open position 88 before being encapsulate in the gel cap 49. The wire frame 86 causes the umbrella shape member 48 to expand radially outward from the collapsed closed shape 58 being coaxial with the inner tubular member 18. The material used to construct the wire frame 86 is preferably titanium or nitinol.


Similar to the previous embodiments, a coupling member 70 is inserted into the outer end 23 of the inner tubular member 18 for selectively passing urine from within the bladder 16 through the inner tubular member 18 and the passageway 72 in the coupling member 70. The inflatable balloon valve 76 within the passageway 72 of the coupling member 70 is operated using a pump 84, as best illustrated by FIG. 12 and FIG. 13.


In FIG. 12 the inflatable balloon valve 76 is in the default, inflated closed position 80. In the inflated closed position 80 the inflatable balloon valve 76 is expanded radially inward away from the inner sidewall surface 74 toward the center 82 of the passageway 72 in sealing engagement with itself. The inflated position 80 of the inflatable balloon valve 76 prevents urine from passing from the inside of the bladder 16. The inflatable balloon valve 76 is deflated to its deflated condition 81 by connecting pump 84 and disengaging plunger 85. As shown in FIG. 13, disengagement of pump 84 causes the plunger 85 to retract drawing saline from within the inflatable balloon valve 76 into the plunger 85 thereby deflating the inflatable balloon valve 76 to a deflated position 81 coaxial with the inner sidewall surface 74 of the passageway 72 for passing urine through the passageway 72. The inflatable balloon valve 76 is re-inflated by releasing or no longer squeezing or pressing the living hinges 92 whereby the living hinges 92 flex outward from the pump 84 body causing the plunger 85 to move downward within the pump 84 to re-inject saline and thereby cause the inflatable balloon valve 76 to expand radially inward away from the inner sidewall surface 74 toward the center 82 of the passageway 72 in sealing engagement with itself to prevent the passage of urine through the passageway 72. The pump 84 is connected to the coupling member 70 and has a pump body. The pump body is preferably constructed of silicon rubber or a like material. The pump 84 has a pump casing 93 in fluid communication with the inflation conduit 77 and inflatable balloon valve 76. The pump 84 utilizes a pair of living hinges 92 that control the deformation and transition of the pump body from an open position 96 to a normally closed position 95.


The term “living” in living hinges 92 refers to the hinges 92 natural preference to remain in or move to the default position in which the hinges 92 are extended outward away from the pump body (in the closed position 95) and the plunger 85 being pressed into the pump casing 93. The living hinges 92 keep a constant downward pressure on the plunger 85 thereby keeping the inflatable balloon valve 76 expanded and in the closed position 80.


The pump body is connected to the plunger 85 at the first end 87 of the plunger 85. The second opposite end 89 of the plunger 85 has ribs 91 for creating a seal between the second end 89 of the plunger 85 and the pump casing 93. The living hinges 92, plunger 85 and pump casing 93 are preferably constructed of a thermoplastic or like material. The living hinges 92 are by default and at all times in the closed position 95, unless manipulated to the open position 96 (See FIG. 13). In the closed position 95, the living hinges 92 are resting in a flexed outward extended position from the pump body and plunger 87. In the closed position 95, the living hinges 92 keep the plunger 89 depressed within the pump casing 93. Keeping the plunger 89 depressed within the pump casing 93 keeps the inflatable balloon valve 76 in the inflated closed condition 80 due to the pressure the living hinges 92 exert on the plunger 85 and the plunger 85 in-turn exerts on the fluid within the pump casing 93 and inflation conduit 77. Thus, in FIG. 12, the pump 84 is shown in the closed position 95 as is the inflatable balloon valve 76. The coupling member 70 consists also of a check valve 79 having an insert 83 for a syringe. The check valve 79 is in fluid communication with inflation conduit 28, which by way of coupling 27 allows connection to inflation conduits associated with any of the embodiments of the control device, as illustrated in FIGS. 1-7. Multiple check valves 79 may be used if multiple inflation conduits 28 are needed to separately inflate different inflatable balloons associated with the different embodiments (See for example FIG. 7).


As shown in FIG. 13, deflation of the inflatable balloon valve 76 is accomplished by squeezing or pressing the living hinges 92 inward toward the body or plunger 87 of the pump 84 and holding the living hinges 92 in the open position 96. In the open position 96, the living hinges 92 are parallel to each other and the plunger 87. In the open position 96, the plunger 85 is retracted outwardly from the pump casing 93 thereby evacuating fluid from within the inflatable balloon valve 76 into the pump casing 93. Drawing fluid into the pump casing 93 evacuates the fluid from the inflatable balloon valve 76 thereby deflating the inflatable balloon valve 76 to an open deflated position 81. In the open deflated position 81, the inflatable balloon valve 76 is coaxial with the inner sidewall surface 74 of the passageway 72 for passing urine through the passageway 72. The inflatable balloon valve 76 is re-inflated by releasing or no longer squeezing or pressing the living hinges 92 inward toward the body or plunger 87 of the pump 84. The natural inclination of the living hinges 92, when released, cause the living hinges 92 to bow outward away from the body or plunger 87 of the pump 84. The movement of the living hinges 92 outward away from the body or plunger 87 of the pump 84 forces the plunger 85 downward into the pump casing 93 thereby re-introducing fluid into the inflatable balloon valve 76 so that the inflatable balloon valve 76 is inflated to its inflated closed condition.


The present invention has been shown and described above with the preferred embodiments, and it is understood that any modifications, substitutions, and additions may be made which are within the intended spirit and scope of the invention. From the foregoing, it can be seen that the present invention accomplishes at least all of its stated objects.
