APPARATUS AND METHOD FOR TRANSMYOCARDIAL REVASCULARIZATION BY LASER ABLATION

摘要

This invention is an apparatus and method for performing transmyocardial revascularization (TMR) wherein epicardial tissue (52) is pushed aside during the formation of a channel (60) in the heart wall (50, 54), and substantially returns to a position coinciding with the channel (60) to act as a channel cap (53) to reduce bleeding from the channel (60).
