Patent ID: 6881201

Claim:
A balloon catheter, comprising: a) an elongated shaft having a proximal end, a distal end, and at least one lumen; b) a balloon on a distal shaft section, having an inflatable interior in fluid communication with the at least one lumen of the shaft; and c) a distal tip defining the distal end of the catheter, having at least a section formed by a distal end portion of the shaft and an outer sheath member bonded together, the outer sheath member comprising a first polymeric material having a higher Shore durometer hardness than a second polymeric material forming an outer surface of the shaft distal end portion, the outer sheath member having a sidewall break at least partially filled with the polymeric material of the outer surface of the distal end portion of the shaft, wherein the sidewall break of the outer sheath member spirals longitudinally at an angle relative to a longitudinal axis of the distal tip.
