Abstract:
Apparatus for percutaneously performing myocardial revascularization comprising:a first catheter adapted for insertion into the left ventricle, the first catheter having a lumen and a distal endface movable to a plurality of sites on an endocardial surface;a stabilizer element disposed on the first catheter, the stabilizer element contacting the endocardial surface to stabilize the first catheter against the endocardial surface;a cutting head disposed movable from a retracted position within the lumen of the first catheter to an extended position wherein the cutting head extends beyond the distal endface of the first catheter to form a channel in cardiac tissue; andmeans for sensing a physiologic state of cardiac tissue in a region adjacent to the distal endface of the first catheter.
