Abstract
The present invention is a device and a method for boring a perfusion channel into the myocardial tissue of a patient. Structurally, the present invention includes a positioning catheter and a cutting catheter. The positioning catheter is formed with an inflation lumen and a deployment lumen and has an inflatable balloon mounted at its distal end. The cutting catheter has a sharpened distal end and is advanceable through the deployment lumen of the positioning catheter. Advancement of the cutting catheter through the deployment lumen causes the distal end of the cutting catheter to be directed radially outward from the positioning catheter. In use, the positioning catheter is positioned within a target vessel. The inflatable balloon is then expanded to anchor the distal end of the positioning catheter. The cutting catheter is then advanced through the deployment lumen, projecting the distal end of the cutting catheter radially outward from the positioning catheter, boring a perfusion channel in the tissue adjacent to the target vessel.
