Abstract:
1. A process for modifying a guide wire for use in a medical procedure, comprising: drawing an elongated core including a nickel-titanium alloy at a distal end; necking down the distal end of the elongated core to create a tapered section leading to a shapeable distal tip; coating the elongated core at least partially with a polymer coating; strain hardening the shapeable tip having superelastic nickel-titanium alloy from a first radial direction to impart crystallographic texture aligned with the first radial direction and eliminate the superelasticity along the shapeable tip; rotating the core about its longitudinal axis; and strain hardening the shapeable tip having superelastic nickel-titanium alloy from a second radial direction to impart crystallographic texture aligned with the second radial direction and eliminate the superelasticity along the shapeable tip.
