PERCUTANEOUS MECHANICAL DILATING CATHETER FOR CARDIAC VALVES AND BLOOD VESSELS

摘要

This invention is a mechanical dilating catheter that serves to dilate stenotic cardiac valves and blood vessels. It is composed of four parts: 1) the handle (1); 2) the sheath (4); 3) the wire (5); 4) the dilating body. This has a concave area (12) in the central section of the expansion blades (8) which firmly anchors the body to the edges of stenotic cardiac valves and to stenotic segments of blood vessels.
