STENT

摘要

A stent (32) configured to be placed in a body lumen and having a tubular shape formed by a structure that is expandable and contractible skeleton (18, 19) in a radial direction, the skeleton (18, 19) having a heteromorphic structure due to changes of a cross section shape thereof in a thickness direction. A stent (10) that is expandable and contractible in the radial direction while being configured to be placed in a body lumen, the stent (10) having a heteromorphic tubular shape, a cross section shape of which changes in a lengthwise direction, and having a metal skeleton (18, 19) formed by at least one of electroforming and etching.

1. A stent comprising a structure of a skeleton that is expandable and contractible in a radial direction so as to have a tubular shape, the stent being configured to be placed in a body lumen, wherein
the skeleton has a heteromorphic structure due to changes of a cross section shape thereof in a thickness direction, and the cross section shape of the skeleton has a substantially reverse triangle shape for which a width dimension becomes larger from an inner circumference surface thereof toward an outer circumference surface thereof.
