Device for anastomosis in a radical retropubic prostatectomy

摘要

An anastomosis method and device is disclosed. In one embodiment, an anastomosis device may include a superelastic stent body having a longitudinal cavity that extends from proximal and distal ends of the stent body. Proximal and distal rows of retractable needles having a substantially concave curvature may be circumferentially positioned around the stent body. The device may be configured so that the proximal and distal rows of retractable needles are individually deployable in approximated lumens, such as a urethra and bladder. Once deployed, the proximal and distal rows of retractable needles respectively engage the urethra and bladder.
