Abstract
Apparatus and methods for intraoperatively performing surgery to create transmural channels in tissue, for example, as in transmyocardial revascularization, are provided using apparatus having an end region containing a mechanical cutting head and means for articulating the end-region to access hard-to-reach portions of the anatomy. The handpiece is coupled by a disposable cable to a controller that houses a vacuum pump and mechanisms for driving the cutting head. The cutting head is adapted to cooperate with the vacuum pump to evacuate tissue severed during the channel forming process.
