APPARATUS AND METHOD FOR TRANSMYOCARDIAL REVASCULARIZATION BY LASER ABLATION

摘要

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