ABSTRACT:
A method of controlling laser energy removal of plaque or other obstructions from a vessel of the cardiovascular system includes advancing a laser delivery catheter to a position in proximity with a targeted lesion, placing a laser energy sensor device in a monitoring position adapted to sense laser energy from the catheter that passes beyond the lesion, and controlling the laser energy according to the output of the sensor. An intraoperative approach places the sensor external to the vessel, while a percutaneous approach places the sensor within the vessel utilizing an additional sensor fiber on the catheter that extends beyond the lesion to the monitoring position. Each fiber in a multifiber laser delivery bundle may be controlled according to sensor output for precision aiming and improved laser control.
