Abstract
A back-up retention member drainage catheter (,) for insertion in the bladder and urethra of a patient undergoing a radical prostatectomy surgical procedure. The drainage catheter includes an elongated tubular member (,) having a drainage lumen (,) extending longitudinally therein with an external drainage port (,) disposed near the distal end (,) of the tubular member. A back-up retention member (,) and, in particular, a first balloon (,) is disposed on the elongated tubular member near the distal end and proximal the external drainage port. A primary retention member (,) and, in particular, a second retention balloon (,) is also disposed on the elongated tubular member around the first retention balloon. First and second inflation lumens (,) extend longitudinally through the elongated tubular member and communicate internally with the first and second retention balloons, respectively. To maintain independent inflation of the two retention balloons, the second inflation lumen communicates externally with the first retention balloon. To maintain the balloons in an expanded state, first and second one-way valves (,) are disposed at the proximal end of the first and second inflation lumens, respectively. A suture tether (,) is positioned through a tether lumen (,) for securing the drainage catheter percutaneously through the patient should the physician so desire.
