Abstract
A guide wire with extension capability for use in a medical procedure having a guide wire and a guide wire extension. The guide wire comprises a flexible elongate cylindrical member having proximal and distal extremities. A portion of the distal extremity is formed of a material having high torquability and high pushability. The guide wire extension comprises a flexible elongate cylindrical member formed of a shape memory material. A major portion of the flexible elongate cylindrical member of the guide wire extension has a shape memory in the form of a coil so that when it is free it will assume a shape memory coil. A junction is formed between the proximal extremity of the guide wire and the distal extremity of the guide wire extension for connection of the guide wire extension to the guide wire.
