Abstract

An incontinence system includes an anchoring mechanism and a channel with a blocking valve positioned in the channel, the blocking valve in a first state prevents urine flow through the channel and in a second state allows urine to flow through the channel. The anchoring mechanism may be a fixation balloon that is contoured to the geometry of the bladder near the opening to the urethra. When urine flows through the channel it flows around a lumen that provides access to the fixation balloon. The fixation balloon may be attached to a shortened Foley-type catheter, with the catheter providing the channel through the balloon. The catheter may contain a lumen that provides access to the blocking valve and it may also contain the lumen that provides access to the fixation balloon. The fixation balloon is inserted in a deflated state and inflated to hold the system in place. The fixation balloon remains inflated with the blocking valve providing continence and allowing voiding. The blocking value may be a conventional valve that is activated remotely or it may be controlled via a lumen or string that connects to the valve and provides access from outside the body. The blocking valve may be a string that expands when relaxed and narrows when stretched.

Claims

1. An incontinence system for controlling urine flow from a bladder through a urethra, the system including:

A. anchoring means for holding the system in position in the body;

B. a channel from the bladder to a proximal end of the urethra;

C. blocking means positioned in the channel to block urine flow through the channel when the blocking means is in a first state and to allow urine to flow around the blocking means, through the channel to the proximal end of the urethra, and through the urethra when the blocking means is in a second state;

D. activation means for controlling the state of the blocking means.

2. The system of claim 1 wherein the channel is a catheter.

3. The system of claim 1 wherein

the anchoring means is a fixation balloon, and

the system further includes a lumen for providing access to the fixation balloon from outside the body for:

i. inflating the fixation balloon after insertion, to hold the fixation balloon in the bladder, and

ii. deflating the fixation balloon when the fixation balloon is to be removed from the body, with urine flowing around the lumen when the blocking means is in the second state.

4. The system of claim 3 wherein the fixation balloon having a shape that is contoured to the bladder and the catheter extends through the balloon.

5. The system of claim 1 further including an everting mechanism.

6. The system of claim 1 wherein

the blocking means is a valve, and

the activation means activates the valve from outside the body.

7. The system of claim 1 wherein

the blocking means is string that in the first state expands to fill a portion of the channel and in a second state narrows to allow urine to flow around the string and through the channel and the urethra, and

the activation means is an end of the string that is moved from a first position associated with the first state to a second position associated with the second state.

8. The system of claim 7 wherein the string is braided.

9. The system of claim 7 wherein the string is made of steel.

10. The system of claim 7 wherein the portion of the channel is the entire channel.

11. An incontinence device including:

A. a fixation balloon that has a deflated state and an inflated state, the fixation balloon being positioned in the body in a deflated state and inflated to prevent urine flow around the balloon from a bladder, the fixation balloon being contoured to the shape of the bladder, and including a channel through which urine is directed from the bladder;

B. blocking means that is positioned in the channel of the fixation balloon, the blocking means having a first state that prevents urine flow through the channel and a second state that allows urine to flow through the channel;

C. activation means for controlling the state of the blocking means; and

D. a lumen for providing access to the fixation balloon from outside the body, the lumen being sized and positioned such that urine flows around the lumen when the blocking means is in a second state.

12. The incontinence device of claim 11 wherein the blocking means is a valve that opens to allow urine to flow through the channel and closes to prevent urine flow through the channel.

13. The incontinence device of claim 12 wherein the activation means controls the state of the valve from outside the body.

14. The incontinence device of claim 12 wherein the valve opens to allow urine to flow through the valve.

15. The incontinence device of claim 12 wherein the valve opens to allow urine to flow around the valve.

16. The incontinence device of claim 11 wherein

the blocking means is string that in the first state expands to fill a portion of the channel and in a second state narrows to allow urine flow through the channel around the string, and

the activation means is an end of the string that is moved from a first position associated with the first state to a second position associated with the second state.
