Abstract

A medical or surgical device (10) creates holes in heart tissue utilizing a needle (20) connected to an energy source (34), such as a radio frequency generator, a resistive heating source, or a microwave energy source. The needle (20) is inserted into heart tissue and activated to heat the surrounding tissue in order to produce reversible tissue damage. The device consists of any energy source (34), and regulator (48), a handle (18), and a needle (20) at the distal end of the handle. A temperature sensor (46) may be positioned on the needle. Preferably, a regulator (48) is connected to the energy source (34), and to the temperature sensor for controlling the temperature of the heart tissue in which the needle has been inserted.
