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 said reservoir and said compression balloon. The compression balloon is inflated in response to fluid flow from said reservoir, when manually compresed by the patient. A manually releasable, one-way valve positioned in the conduit between said reservoir and said compression device 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.
