Abstract
A system for performing fluid jet myocardial revascularization includes a catheter having a proximal region, a distal region, a lumen extending therethrough and a valve disposed in the lumen for allowing the passage of fluids in the lumen to create holes in the myocardium. A valve control means extends through the proximal region of the catheter to open and close the valve. In one embodiment, the valve also includes a biasing mechanism for biasing the valve in a closed position. The valve may be controlled using an electrically actuated device that is heated with an electrical current to open and close the valve. In one embodiment of the invention, the catheter has a wall that can be expanded within a guide catheter to anchor the catheter during revascularization.
