Abstract
A gauging system for monitoring channel depth in percutaneous endocardial revascularization surgery includes a catheter for percutaneous insertion into a heart chamber, including a source of tissue ablative energy for ablating a part of the wall of the heart chamber where a channel is to be created; a sensor device proximate the distal end of the catheter for sensing a boundary of the heart wall proximate the channel; and a detection circuit, responsive to the sensor device, for determining the position of the terminus of the channel in the heart chamber; alternatively, a mechanical stop extending radially beyond the distal tip may be used for physically limiting penetration of the catheter tip into the drilled channels.
