Title: GUIDEWIRE DEVICES HAVING DISTALLY EXTENDING COILS AND SHAPEABLE TIPS
Abstract:
The present disclosure relates to guidewire devices having shapeable tips and effective torquability. A guidewire device includes a core having a proximal section and a tapered distal section. A tube structure is coupled to the core such that the tapered distal section of the core extends into and distally beyond the tube structure. The portion of the core extending distally beyond the tube forms a shapeable tip. One or more coils also extend distally beyond the tube. The tip is configured to reduce the tendency of resilient forces from the tube structure to disrupt a customized shape of the tip.
