Abstract:
The instrument (10) disclosed comprises a tube assembly (500) supporting an end effector that may be adapted for insertion into and through the urethra into the bladder lumen or into the bladder lumen through incisions in the abdomen and bladder wall and adapted for use in effecting the anastomosis of a patient's bladder and urethra following a prostatectomy. The instrument (10) may include an end effector having a positioner (400), an anchor driver (300) and anchor system (700) comprising a shaft (720) with a lodging structure (730), and/or a combined balloon harness (94) and catheter (96). The instrument (10) urges the bladder wall to the pelvic floor and drives an anchor (700) through the bladder wall into the pelvic floor, thereby connecting a balloon harness (94) within the bladder to the pelvic floor that presses the bladder wall against the pelvic floor; maintaining the balloon catheter (96) in place and draining the bladder during the time required for the tissues to effectively knit; and then deflating and withdrawing the balloon catheter (96) and disconnecting and withdrawing the balloon harness (94).
Abstract:
An electrode assembly for a resectoscope (18) includes a cutting electrode (1) with a loop distal tip and a first power density. A coagulation electrode (2) has a loop distal tip and a second power density that is smaller than the first power density. A support frame is connected to the cutting and coagulation electrodes (1, 2) and to an energy source (24) to supply energy from the energy source (24) to the cutting and coagulation electrodes (1, 2). The coagulation electrode (2) provides tissue coagulation simultaneously while the cutting electrode (1) cuts tissue. A resectoscope (18) is disclosed which includes the electrode assembly. The resectoscope includes a sheath (14) with a sheath lumen (14a, 14b), a working element (15), and a visualization apparatus (16).

Abstract:
Disclosed is an instrument for use in a procedure to effect anastomosis of a patient's bladder and urethra following a prostatectomy having a tube assembly, and an end effector assembly operably supported by the tube assembly. The end effector assembly includes a positioner assembly, an anchor driver assembly and an anchor for insertion into and through the patient's bladder wall and pelvic floor and an anchor guide associated therewith. The end effector also includes a harness adapted to receive a balloon portion of a balloon catheter assembly.
