Abstract
A catheter having an elongated shaft, a balloon on a distal shaft section, and a distal tip having at least a section formed by a distal end portion of the shaft and an outer sheath member fused together. The outer sheath member has a sidewall break at least partially filled with the polymeric material of the outer surface of the distal end portion of the shaft. The outer sheath member preferably comprises a first polymeric material having a higher Shore durometer hardness than a second polymeric material forming the outer surface of the shaft distal end portion. One aspect of the invention is directed to a method of making a balloon catheter, in which the polymeric material of the outer surface of the shaft is caused to soften and flow into the opening formed by the break in the sidewall of the outer sheath, thus forming the distal tip.
