Abstract:
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.
