COIL REINFORCED SUPERELASTIC GUIDEWIRE

Abstract:

A guidewire formed from a superelastic material has a proximal section and a distal section. In order to improve torque and pushability in the proximal section, a first wire is wound clockwise onto the proximal section to form a first coil and a second wire is wound counterclockwise onto the first coil to form a second coil.
