Abstract
An intravascular medical catheter and method of manufacturing a medical catheter are provided herein. The medical catheter includes a guidewire shaft, a sleeve, and a balloon. The sleeve is attached to the guidewire shaft while a distal tail of the balloon is thermally bonded to the sleeve. Because of the sleeve, the distal tail of the balloon can be thermally bonded even if the guidewire shaft is made of a material which is thermally incompatible with the balloon. Thus, for example, a medical catheter can be made with an HDPE guidewire shaft and a balloon made of PEBA, PET, Polyurethane, or Nylon. The resulting medical catheter has a catheter tip which is durable, flexible, and has a relatively low profile for good tracking in the body vessel and good lesion crossing.
