Patent ID: 8801770

Claim:
A stent configured to closely contact tissue in vivo by being deformed when set indwelling in vivo, the stent comprising: a plurality of linear components configured to deform and exhibit a force for maintaining dilation when the stent is set indwelling in vivo, the linear components comprising a plurality of non-biodegradable metallic linear components and a plurality of biodegradable material-made linear components, the biodegradable material-made linear components being bonded to the non-biodegradable metallic linear components; both the non-biodegradable metallic linear components and the biodegradable material-made linear components contributing to the stent exhibiting the force for maintaining the dilation when the stent is left indwelling in vivo; and after a predetermined period of time following the stent being left indwelling in vivo, biodegradation of the biodegradable material-made linear components proceeds so that the force for maintaining the dilation is lowered; and wherein the non-biodegradable metallic linear components have at least one joint part which protrudes from a side portion of a rectilinear portion of the non-biodegradable metallic liner components, and the biodegradable material-made linear components envelop only a free end of the at least one joint part.
