Insert molded hub and strain relief

摘要

A hub assembly and methods of attaching the same to a catheter shaft. The hub assembly includes a strain relief coupled to a hub. The strain relief may be mechanically coupled to the hub. The hub assembly may be manufactured in a non-clean room environment, and subsequently connected to the catheter shaft in a clean room.

主权项

1. A method of attaching a hub to a catheter shaft, comprising:
providing a strain relief; inserting at least a portion of the strain relief into a mold; injecting a polymeric material into the mold to form a hub having a distal end such that at least a portion of the strain relief extends into the hub and such that no portion of the strain relief proximal of the distal end of the hub is outside the hub; removing the hub from the mold to provide a hub assembly comprising the hub and the strain relief; providing a catheter shaft having a proximal end; and subsequent to the step of removing the hub from the mold to provide a hub assembly, bonding the strain relief of the hub assembly to the proximal end of the shaft, wherein the step of injecting a polymeric material into the mold to form a hub includes the step of mechanically interlocking the strain relief to the hub.
