Abstract
The present invention is a device for incision and dilation of stenotic segments within the vascular system of a patient. Structurally, the present invention includes a rigid ellipsoidal dilation probe mounted at the distal end of a catheter. A series of longitudinally oriented blades project radially from the surface of the probe. A tapered inflatable balloon is also mounted on the catheter in a position that is proximal to the dilation probe. In use, the probe and catheter are advanced over a guidewire to reach the targeted stenotic segment. The probe and blades are then advanced through the stenotic segment to incise the stenosis. The balloon may then be inflated to adopt a tapering fusiform shape, allowing the balloon to be advanced through the stenosis to further dilate the stenosis. Alternatively, the balloon may be positioned across the stenosis and inflated to dilate the stenosis. The fusiform shape of the balloon matches the tapering geometry of many coronary arterial vessels, decreasing the chances that a segment of the vessel will be overpressurized by the inflating balloon.
