Fundamental research of the next-generation stent was done. The treatment method of intimal hyperplasia in the amputation stump section was examined. The procedure of changing the form of an end piece, the method of changing the Nitinol pipe thickness, the procedure of carrying out polishing strong only against the limb section, the method of changing the memory by heat treatment, etc. were proposed.
