This technology includes a guidewire purpose-built for delivery of bulky transcatheter heart valves (THV). Conventional THV guidewires are rigid and have a distal tip shaped like a pigtail to prevent apical ventricular perforation. This invention is a 3-dimensional helical or antihelical curve that can protect against apical perforation, possibly better, and that allows subtle 3-mensional deflection to aid the operator in achieving coaxiality or overcoming delivery obstacles such as calcific spicules.

Commercial Applications
Guidewire for use during transcatheter heart valve procedures.

Competitive Advantages
This simple device modification can ease and speed delivery of transcatheter heart valves over conventional designs.
