ABSTRACT:
A transmyocardial revascularization catheter which includes an elongate drive shaft having a proximal end, a distal end and a longitudinal axis. The TMR catheter also includes a cutting tip disposed at the distal end of the shaft. The tip has a distally disposed cutting edge and a longitudinally extending lumen therethrough. A motor is coupled to the drive shaft for rotation of the cutting tip. The shaft defines a longitudinally extending lumen in fluid communication with the tip lumen.
