Helical Guidewires and Related Systems for Transcatheter Heart Valve Procedures
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,...
