Abstract
Abstract A medical instrument stabilizer for use in endoscopic procedures includes a stabilizer body for being placed against an external surface of an anatomical cavity wall and having a port for receiving medical instruments to be introduced into the anatomical cavity through the stabilizer body and the anatomical cavity wall. An anchoring system carried by the stabilizer body includes a tissue penetrating member movable between a retracted position wherein a tissue penetrating tip of the tissue penetrating member is disposed in a safe, non-exposed position and an extended position wherein the tissue penetrating tip extends from the stabilizer body to penetrate the anatomical wall and anchor the stabilizer thereon. Medical instruments inserted into the anatomical cavity through the port of the stabilizer are secured relative to the stabilizer and, therefore, the anatomical wall. Anchoring of the stabilizer to the anatomical wall by the tissue penetrating member permits manipulation of the anatomical wall by urging the stabilizer and/or the inserted instruments in a desired direction.
