Abstract
Disclosed is a guide wire having a coil surrounding a core of the guide wire and a stiffness transition element. The stiffness transition element is configured to provide a smooth stiffness transition from the distal end of the guide wire to the coil and/or the core of the guide wire. The stiffness transition element may be formed of any medical grade polymer.
Claims19
A guide wire comprising:
- an elongate body having a distal end;
- a coil comprising successive turns, the coil surrounding at least a distal portion of the elongate body;
- and
- a transition element configured to provide a smooth stiffness transition from the distal end of the elongate body to the coil.
1 more element
A guide wire comprising:
- a polymer distal tip, configured to provide an atraumatic distal end to the guide wire;
- a wire member, embedded in the polymer tip and extending proximal of the polymer tip;
- a coil surrounding at least a portion of the polymer tip;
- and
- a transition element positioned about the wire member such that the transition element provides a smooth stiffness transition from the polymer tip to the coil.
