Guidewire extension with selflatching detachable connection.

摘要

A guidewire system (12) for use in catheter exchanges avoids the need for a separate exchange wire (20) by connecting an extension wire (30) 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.
