Latest Patents

Yamada holds a patent for a guide wire for a catheter. This invention includes a core wire and a sheath that covers at least the distal end of the core wire. The core wire is made from a nickel-titanium alloy with a nickel-titanium ratio ranging from 3:2 to 1:1. Notably, the core wire is designed to exhibit a recovery percentage of at least 90% when elongated by at least 5% in a tensile test. Furthermore, elongations between 0% and 5% do not induce stress-related martensitic transformations or austinite reverse transformations. This unique property ensures that the load-elongation characteristics of the nickel-titanium alloy maintain a proportional or gradually decreasing load increase throughout the elongation range of 0 to 5%. Yamada's patent represents a significant advancement in catheter technology.
