Abstract: A catheter including an elongated highly flexible hollow lumen (12) and a guide wire (14) positioned within the lumen, the guide wire fabricated from nickel-titanium shape-memory alloy, the guide wire having greater than three percent (3 %) elasticity over the temperature range of use of the catheter allowing high-elastic deformation at low stress and low rolling and sliding frictional resistance of the guide wire when moved and bent within the lumen producing a high degree of tactile control is disclosed.
