ABSTRACT:
A guidewire system for use in catheter exchanges avoids the need for a separate exchange wire by connecting an extension wire to the proximal end of the guidewire thereby increasing the effective length of the guidewire to permit a catheter exchange. The proximal end of the guidewire is attached to the distal end of the exchange wire by a disconnectable reattachable connection which avoids deformation of the connected joint.
