ABSTRACT:
An over-the-wire balloon catheter for use in angioplasty includes a dual lumen shaft formed by a multi-section outer tube with a multi-section inner tube coaxially aligned therein. The outer tube includes a proximal hypotube outer tube section which is connected to a manifold at its proximal end. The outer tube also includes a distal high density polyethylene outer tube section which is attached to the distal end of the proximal outer tube section at an outer tube bonding region. The inner tube has a proximal polyimide inner tube section which extends generally coaxially through the proximal outer tube section. The inner tube also includes a distal high density polyethylene inner tube section which is attached to the distal end of the first inner tube section at an inner tube bonding region. The inner tube bonding region is spaced proximally from the outer tube bonding region, and a balloon is attached to the distal ends of the outer and inner tubes.
