Abstract
Devices and methods for providing an elastically deforming guidewire tip, capable of withstanding the extreme forces of high-speed rotational atherectomy, in particular orbital motion induced by an eccentric abrasive head, are disclosed. In certain embodiments, the reformable tip comprises an inner nitinol support coil, wherein the reformable tip may be attached to a larger proximal core for improved kink resistance and support for delivering adjunctive devices. In other embodiments, an inner nitinol support coil may be wrapped with a braided coil and/or a polymer sleeve. The resulting tip is more flexible with reduced risk of perforation than known guidewire tips.
