低侵襲インプラントに適した小型フォームファクタの自己拡張型NiTiフレームの迅速な形成と試験

Executive Industry Relevance

Rapid prototyping of self-expanding NiTi frames addresses a critical bottleneck in early-stage medical device development, enabling faster iteration and evaluation of implantable structures. This approach reduces the cost and time associated with traditional shape-setting, supporting agile design cycles for minimally invasive implants. The methodology enhances portfolio agility by allowing R&D teams to quickly assess device feasibility and performance before scale-up.
