Claim:
1. A device for removing excess myocardium during treatment of hypertrophic cardiomyopathy, comprising: a catheter having a proximal opening and a distal opening; a cutting device, having proximal and distal ends, disposed at the distal opening of the catheter, wherein the cutting device is comprised of an outer shell having a singular elongated void with beveled ends disposed in a wall of the outer shell and a plurality of holes disposed at rounded tip of the distal end of the cutting device; a tubular blade slideably disposed within the outer shell, wherein the tubular blade contains a singular elongated void with beveled ends, wherein the void of the tubular blade is a similar shape to and is aligned with the void of the outer shell when in a repose position, wherein the void of the tubular blade is configured to receive the excess myocardium; and at least one wire that facilitates sliding of the tubular blade, transfers electrical information to prevent bundle branch damage, and transmits current for coagulation at a myectomy site to prevent fistulas, wherein the wire has a first end and a second end, the first end of the wire being in mechanical communication with the tubular blade, the second end of the wire being in mechanical communication with a surgical device.
