Patent number: 8454673Abstract: 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. A distal leg of the balloon is directly or indirectly affixed to the inner body, and a proximal leg of the balloon is affixed to the distal end of the outer body. 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.Type: GrantFiled: October 18, 2010Date of Patent: June 4, 2013Assignee: Cordis CorporationInventors: Laila Al-Marashi, David Grewe, Stephen Griffin, Elaine Lim, David Majercak, Roger Stevens
