Patent ID: 8021311

Claim:
A method for manufacturing an intravascular medical device, the method comprising: providing an elongate metallic tubular member defining an inner lumen and having an inner surface, the inner surface including a metal oxide formed thereon; providing an elongate core wire having a proximal end, a distal end, and at least one tapered region adjacent the distal end; inserting a scoring tool into the lumen of the tubular member; mechanically scoring at least a portion of the inner surface to remove at least some of the metal oxide with the scoring tool to create a bonding zone along the inner surface; disposing the core wire in the lumen of the tubular member; attaching the core wire to the tubular member at one or more attachment points adjacent to a proximal end of the tubular member; disposing a coil member over the distal end of the core wire and within the lumen of the tubular member such that a distal end of the coil member is disposed adjacent the bonding zone; attaching a proximal end of the coil member to the core wire; and soldering a distal tip to the bonding zone; wherein the distal end of the coil member extends distally into the distal tip; and wherein the scoring tool includes a rotary blade.
