Abstract

A medical system is disclosed which includes an over-the-wire type balloon catheter and a guide wire wherein the catheter includes a polymer outer tube, and an inner tube having a metallic proximal portion and a polymer distal portion. An inflatable balloon is connected to the distal ends of the inner tube and the outer tube. The guide wire may be removed from and inserted into the guide wire lumen at either end of the catheter. The catheter may further include a transition member traversing the junction between the proximal and distal portions of the inner tube. The transition member may be in the form of a wire, a coil or a tube, and may be made of cold drawn stainless steel or a superelastic alloy. The metallic proximal portion of the inner tube may have a wall thickness greater than or equal to 0.0020 inches and an outside diameter less than or equal to 0.0255 inches. The catheter may also include a radiopaque marker band swaged onto the inner tube. A method of manufacturing a balloon catheter is also disclosed which includes the steps of: (1) placing a support member inside a tubular member; (2) sliding a balloon over the tubular member such that the bonding region on the tubular member is aligned with a bonding region on the balloon; (3) placing a heat shrinkable tube over the balloon aligned with the bonding regions; (4) exposing the heat shrinkable tube and the bonding regions to heat (e.g. infrared) such that the heat shrinkable tube exerts a compressive force onto the balloon, the bonding regions flow, the balloon bonding region is radially compressed onto the tubular member bonding region, and the bonding regions form a tip which is tapered in a distal direction. A heat shield may be used to expose only the bonding regions and the heat shrinkable tube. An adhesive (e.g. urethane) or a tie polymer may be applied to either of the bonding regions.
