Incontinence bladder control method and apparatus
First Claim
1. An implantable apparatus for controlling urinary incontinence in a patient, comprising:
- a reservoir containing fluid positionable subcutaneously over the patient'"'"'s anterior pubis;
inflatable compression means positionable intrapelvically above the patient'"'"'s pelvic diaphragm between the patient'"'"'s posterior pubic symphysis and urethra of occluding the urethra;
conduit means arranged to extend over the patient'"'"'s superior pubis through the abdominal wall between said reservoir and said compression means to provide fluid communication therebetween for inflating the compression means in response to fluid flow from said reservoir;
said inflatable compression means being arranged to compress against the urethra and/or bladder neck along an extended area of only the anterior side thereof and including means for directing inflation of the balloon preferentially in a direction normal to the dimension of said cross-sectional shape so as to compress the urethra in an inferior-posterior direction.

Abstract
A method and apparatus for controlling urinary incontinence in a patient includes positioning a reservoir containing fluid subcutaneously over the patient'"'"'s anterior pubis; an inflatable compression balloon between the patient'"'"'s posterior pubic symphysis and urethra; and a conduit extending over the pubis for fluid communication between a reservoir and a compression balloon. The compression balloon is inflated in response to fluid flow from the reservoir, when manually compressed by the patient. A manually releasable, one-way valve positioned in the conduit between the reservoir and a compression balloon retains fluid in the compression balloon under pressure and is externally actuable by the patient for equilibrating pressure in the reservoir and compression balloons to permit voiding. The bladder of the patient is elevated and connected anteriorly to the patient'"'"'s abdominal wall by a felt matrix or mesh patch affixed to the bladder to effectively lengthen and stabilize the urethra. The compression balloon is arranged and positioned to compress in an inferior-posterior direction solely against an extended area the anterior side of urethra for occluding the urethra.

8. An implantable apparatus for controlling urinary incontinence in a patient, comprising:
-
a reservoir containing fluid positionable subcutaneously over the patient'"'"'s anterior pubis; inflatable compression means positionable intrapelvically above the patient'"'"'s pelvic diaphragm between the patient'"'"'s posterior pubic symphysis and urethra for occluding the urethra; conduit means arranged to extend over the patient'"'"'s superior pubis through the abdominal wall between said reservoir and said compression means to provide fluid communication therebetween for inflating the compression means in response to fluid flow from said reservoir; said inflatable compression means being arranged to compress against the urethra and/or bladder neck along an extended area of only the anterior side thereof, the compression means comprising an inflatable balloon having a semirigid skirt surrounding an entrance portion of the balloon for directing the expansion of the balloon preferentially in a direction axially of the balloon from said entrance so as to compress the urethra in an inferior-posterior direction.

9. An implantable apparatus for controlling urinary incontinence in a patient, comprising:
-
a reservoir containing fluid positionable subcutaneously over the patient'"'"'s anterior pubis; inflatable compression means positionable intrapelvically above the patient'"'"'s pelvic diaphragm between the patient'"'"'s posterior public symphysis and urethra for occluding the urethra; conduit means arranged to extend over the patient'"'"'s superior pubis through the abdominal wall between said reservoir and said compression means to provide fluid communication therebetween for inflating the compression means in response to fluid flow from said reservoir; said inflatable compression means being arranged to compress against the urethra and/or bladder neck along an extended area of only the anterior side thereof, the compression means comprising an inflatable balloon having a sidewall of variable thickness, the thickness being greatest in an entrance portion of the balloon and least in an end portion remote from the entrance of the balloon for directing the expansion of the balloon preferentially in a direction axially of the balloon from said entrance so as to compress the urethra in an inferior-posterior direction.
