摘要：
A balloon catheter or stent delivery system for medical treatment of a patient has a proximal hub, a balloon, and an improved shaft design The catheter shaft has a rapid-exchange configuration, and a tubular outer body that includes a hypotube extending from the catheter proximal end to a position at or near a proximal leg of the balloon An inner tubular body defines a guidewire lumen extending from a distal guidewire port at the catheter distal end to a proximal port located at a position between the balloon and the hub The hypotube has an aperture for accepting the inner body proximal end, and a circumferential cut pattern The cut pattern adds flexibility, and may extend from the hypotube distal end to a position proximal of the proximal guidewire port
