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, anchoring structure 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 anchoring structure 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.
