Abstract

A device for treatment of human urinary incontinence in the form of a catheter which can be inserted into the urethra and carries a balloon arrangement which can be filled with fluid to close off the urinary bladder, where the balloon arrangement holds the catheter in the lumen of the bladder. The fluid can be admitted to and discharged from the balloon arrangement via at least one channel running along the catheter wall which is closed off at the distal end of the distal part of the catheter. A self-closing valve is formed at a proximal end of the proximal part of the catheter. A hydraulic actuating mechanism is also located in the lumen of the urinary bladder. The hydraulic actuating mechanism can be hydraulically actuated by mechanical pressure exerted on a compressible balloon located at the distal end of the catheter. The compressible balloon is filled with fluid and is connected to the actuating mechanism via a connecting channel.

a. a longitudinal elongated catheter having a proximal part and a distal part, each part having a proximal end and a distal end, the catheter being installable within a urethra of the human being such that the proximal end of the proximal part extends into a bladder of the human being;

b. hollow connecting means connecting said proximal and distal parts of said catheter together and forming a gap between said distal end of said proximal part and said proximal end of said distal part;

c. a compressible lower balloon being actuated from outside of the urethra and integrally formed to said distal end of said proximal part and said proximal end of said distal part, and completely enclosing and sealing said gap to form a greater volume range to compress the compressible lower balloon, the compressible lower balloon filled with fluid thereto by a first channel running along the interior of said distal part of said catheter;

d. a flexible expandable and contractible middle balloon integrally formed with the exterior of said catheter at said proximal part for maintaining the position of said catheter within the urethra;

e. a flexible expandable and contractible upper balloon integrally formed with the exterior of said catheter at said proximal part and located adjacent to said proximal end for maintaining the position of said proximal end of said proximal part of said catheter within the bladder, the upper balloon being fillable with fluid by a second channel running along the interior of said distal and proximal parts of said catheter which in turn fills said middle balloon by a third channel connecting the upper balloon with said middle balloon, the upper balloon being larger than said middle balloon;

f. a valve formed on said proximal part of said catheter and located adjacent to said proximal end;
