Partial-length, indwelling prostatic catheter using coiled inflation tube as an anchor and methods of draining urine and flushing clots
InactiveUS20050059929A1Minimize discomfortReduce painStentsBalloon catheterSphincterSurgical department
An indwelling catheter is positioned in a urinary tract to drain urine from the bladder to a position distally adjacent to a sphincter muscle. A balloon of the catheter is inflated through an inflation tube extending through the urinary tract. A coiled section of the inflation tube contacts the constriction caused by the sphincter muscle. The balloon and the coiled section resist movement of the indwelling catheter while still permitting natural urination. The indwelling catheter is inserted by an insertion tool which is separably connected to the catheter. Once the indwelling catheter is positioned, the tool is disconnected and withdrawn from the urinary tract. Risks of blood clots obstructing the flow of urine through the indwelling catheter immediately following a surgical procedure on the prostate gland are avoided by flushing fluid through the insertion tool and the catheter to clear an internal urine flow passageway in the catheter.
