| 摘要 |
The present invention is a method of bonding a shaft tip to a distal end of a catheter or sheath shaft. The method includes extruding a shaft to have an initial outside diameter that is greater than an outside diameter the shaft will have when finished. A lap joint area is then ground into the distal end of the shaft. The tip is then insert molded over the lap joint area. The tip includes a collar at a proximal end of the tip that provides additional thermal mass to facilitate the bonding of the tip to the shaft. The shaft is then ground from its initial outside diameter to its finished outside diameter.
