Living tissue attachment surface, implant, method of forming living tissue attachment surface, method of manufacturing implant

摘要

The living tissue living surface (30) in close contact with the living tissue (H, S) is made of a biocompatible material and has many finger-shaped microvilli (41). The microvillus (41) has a tip diameter of nanometer size. The implant (1) has a living tissue living surface (30) on the surface (11, 24) to be attached to the living tissue (H, S). In the method of forming the living body tissue attachment surface (30), laser non-thermal processing of irradiating laser light in the air is applied to the surface of the biocompatible material to form a large number of finger-shaped microvilli (41). The laser light is a laser light of an ultrashort pulse laser.
