Abstract: PURPOSE: A variable helix medical device is provided, which prevents inward enlargement of the tumor tissue cell and inner cavity cell and stricture of the inner cavity. CONSTITUTION: A variable helix medical device is constituted as follows. The variable helix medical device is formed into a helix body with predetermined helix width and helix number. The variable helix medical device has expansion and reduction driving characteristic of the helix body by generating heat through induction heating by the high frequency alternating current provided from the outside. The shape memory polymer is polyurethane(200). The polyurethane is composed of a soft segment and a hard segment.
