Abstract:
A device for treatment of human urinary incontinence to be used by a human being, comprising: 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; g. retaining means formed across said valve for further maintaining said valve closed; and h. a hydraulic actuating mechanism having an expandable and contractible tiny balloon located on said proximal part of said catheter and adjacent to and on the opposite side of said valve, and traction means formed on said proximal part of said catheter and tightly covering the expandable and contractible tiny balloon, whereby when pressure is exerted on said lower balloon, the fluid from said lower balloon flows through a fourth channel running along the interior of said proximal part and connects the tiny balloon which in turn fills and expands against the traction means to move a portion of said catheter to open said valve while said catheter remains within said human being to permit urine to be discharged from the bladder, and when the pressure is removed from said lower balloon, the fluid flows back to the fourth channel into said lower balloon and thereby closes said valve after the urine has been evacuated from the bladder; i. whereby said catheter remains in its inserted condition in the human being for the purposes of both closing off the flow of urine from the bladder and also permitting the urine to be evacuated from the bladder while the catheter remains in its inserted condition in the human being.
