Patent ID: 7854755

Claim:
A system, comprising: an elongate catheter body having a first lumen and a second lumen extending between a proximal end and a distal end of the elongate catheter body; a first cutting head having a blade and an elongate pulling member, the elongate pulling member extends through the first lumen and slides within the first lumen to move the first cutting head relative to the distal end of the elongate catheter body; a second cutting head having a blade, the second cutting head positioned adjacent to the distal end of the elongate catheter body between the distal end and the first cutting head; an inflatable balloon positioned adjacent to the distal end of the elongate catheter body and proximal to the second cutting head, the inflatable balloon in fluid tight communication with the second lumen; an expandable stent positioned over at least a portion of the inflatable balloon, where the blade of the first cutting head moves relative to the blade of the second cutting head to provide a shearing action for cardiac tissue and the inflatable balloon deploys the expandable stent over sheared cardiac tissue; and an expandable filter positioned within a lumen of a sheath and proximal to a cardiac valve, wherein the elongate catheter body is positioned at least partially within the lumen of the sheath, and wherein the sheath moves relative to the cardiac valve and the expandable filter to deploy the cardiac valve and at least a portion of the expandable filter and wherein both the cardiac valve and the expandable filter are positioned toward the proximal end relative to the inflatable balloon and the expandable stent.
