Urethral muscle controlled micro-invasive sphincteric closure device

摘要

A rod-like or tube-like sphincteric closure device (151) is micro-invasively implanted beneath the surface of the posterior mucosal wall (119) to elevate the mucosa (113) and close the lumen (100), by using a delivery device operated through the urethra (101). To initiate voiding, the muscle-rich anterior urethral wall contracts and widens the lumen beyond the closing or elevating range of the sphincteric closure device (151). For urethral obstruction, repelling magnets are micro-invasively implanted beneath the surface of mucosa with the delivery through the urethra, to widen the lumen with magnetic force.
