TISSUE RESECTION DEVICE HAVING A REMOVABLE ABLATION/COAGULATION CLIP

摘要

The present invention provides a tissue resection device comprising a shaft (22) having an aperture, a cutting member (18) disposed adjacent to the aperture, and a chopping mechanism disposed within the lumen of the shaft. An electrically conductive surface (23) is disposed near the cutting member (18) to apply coagulative or ablative energy to a surface of remaining tissue. Preferably, the cutting member (18) comprises a transverse electrosurgical cutting wire, and the conductive surface (23) comprises a roller aligned with the wire so that as the wire severs a strip of tissue proximally, the strip is aspirated through the aperture while the roller cauterizes any open blood vessels.
