Method of using neovascularization catheter
First Claim
1. A method for treating a deficiency of blood flow from a coronary artery to a cardiac muscle, the method comprising the steps of:
- advancing a positioning catheter into the coronary artery;
anchoring a portion of the positioning catheter in the coronary artery;
advancing a cutting guidewire into the cardiac muscle; and
creating a perfusion channel with a cutting catheter which extends away from the positioning catheter, the perfusion channel extending from the artery into only a portion of the cardiac muscle, the perfusion channel allowing blood flow from the coronary artery to the cardiac muscle.

Abstract
The present invention is a device and a method for boring a perfusion channel from a coronary artery into a cardiac muscle of a patient. Structurally, the present invention includes a positioning catheter, anchor means and a cutting catheter. The cutting catheter includes a plurality of blades and is advanceable through a deployment lumen of the positioning catheter. Advancement of the cutting catheter through the deployment lumen causes a distal end of the cutting catheter to project laterally from the positioning catheter. In use, the positioning catheter is positioned within the coronary artery. The anchor means is then expanded to anchor the positioning catheter within the artery. The cutting catheter is then advanced through the deployment lumen to bore one or more perfusion channels in the myocardial tissue.
