SHAPE MEMORY THIN FILM COMPOSED OF STRONGLY HYDROGEN ABSORBING ALLOY, SHAPE MEMORY COMPOSITE MATERIAL COMPOSED OF STRONGLY HYDROGEN ABSORBING ALLOY, AND SOFT CATHETER FOR MEDICAL USE

摘要

PROBLEM TO BE SOLVED: To provide a shape memory thin film that is composed of a strongly hydrogen absorbing alloy, can be deformed by overcoming the resistance from the surrounding bio-tissue of a bodily temperature area of a human being by revealing a strong shape memory effect, has good bio-compatibility and a human body-friendly soft property, and can reveal a shape memory effect even when the thin film is not heated, and to provide a shape memory composite material composed of the strongly hydrogen absorbing alloy and a soft catheter for medical use. SOLUTION: The shape memory thin film composed of the strongly hydrogen absorbing alloy is composited by diffusing fine LaNix-based alloy particles in a polymer material.
