Abstract
Apparatus and methods for defibrillating a heart in fibrillation are provided using apparatus that forms a plurality of transmural channels in a wall of the heart. The apparatus includes a single-use handpiece having a mechanical cutting head and means for stabilizing the cutting head in contact with the tissue. 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.
