Abstract
A method of locating a constriction in a coronary artery and performing an arteriotomy distally thereof which comprises locating the site of a constriction in a coronary artery by scanning the artery with a non-invasive sensing instrument capable of detecting the constriction. The sensing instrument has associated therewith a cutting instrument comprised of a cutter and member for moving the cutter into a position for making an incision. After the constriction is located, the cutting member is moved into a cutting position distal of the constriction and an incision is made through the wall of the artery into the lumen thereof.
