GUIDEWIRE HAVING PARABOLIC GRIND PROFILE

Abstract:

A guidewire for use in intravascular procedures has an elongated core member including a proximal core section having a uniform diameter. One or more parabolic grind profile sections extend distally from the distal end of the proximal core section and provide a linear change in bending stiffness and a high degree of torque to the distal portion of the guidewire.
