Abstract
A partially biodegradable stent includes a main net body of hollow cylindrical shape formed of elastically deformable wires interlaced with each other, the net body extending in a longitudinal direction and terminating at open opposite ends, and an auxiliary net portion provided at one of the open opposite ends of the main net body, the auxiliary net portion formed of a biodegradable wire which can be degraded and removed by a bodily fluid. The auxiliary net portion is formed by interlacing the biodegradable wire into a cylindrical shape independently of the main net body or by interlacing the biodegradable wire with the elastically deformable wires at one of the open opposite ends of the main net body.
