ABSTRACT:
A method and apparatus are provided for withdrawing an indwelling over-the-wire catheter from an indwelling guidewire in which the guidewire is of a conventional length and is maintained in its indwelling position as the catheter is withdrawn. The position of the guidewire is maintained by constraining a segment of the catheter shaft and its included guidewire in a non-linear configuration such that the guidewire remains in its position as the catheter is withdrawn. The invention may be used to perform catheter exchanges without requiring the use of exchange wires, extension wires, rapid exchange catheters or special devices to connect the guidewire to the guide catheter.
