<p>PROBLEM TO BE SOLVED: To provide a stent with relatively less sacrificed radial strength, if much lengthened, and capable of more closely matching to the elongation of a conduit to be inserted without sacrificing the radial strength. SOLUTION: Specified 'given separation' points or areas are provided for a stent 1. After the stent 1 is developed, the stent 1 is separated at these given separation points or areas with stress applied to the stent 1. When separation occurs throughout the whole periphery of the stent 1, the stent 1 is separated into stentor sections 2 each of which can be moved together with a conduit, independently from other stentor sections 2. Components in the given separation areas 3 have cross sectional areas small enough for separation with stress applied to the stent 1 after inserted. Alternatively or additionally, the components in the given separation areas 3 can be formed of material weak enough for separation with stress applied to the stent: 1 after inserted. The stent 1 has a less number of components in the given separation areaa 3 than the stent sections.</p> |
