Zusammenfassung:	PROBLEM TO BE SOLVED: To provide implants having high fatigue resistance, implant delivery systems, and methods of use.SOLUTION: A fatigue resistant stent includes a flexible tubular structure having an inside diameter, an outside diameter, a sidewall between the inside diameter and the outside diameter, and apertures extending through the sidewall. The apertures separate struts 6A joined at apices 6B, and the apices have a structure to exhibit a level of tensile strain. According to other aspects of the invention, processes for making a fatigue resistant stent are disclosed. According to further aspects of the invention, delivery systems for a fatigue resistant stent and methods of use are provided. 【課題】高い疲労抵抗を有する移植片、移植片送達システム、および使用法を提供する。【解決手段】疲労抵抗ステントは、内径と、外径と、内径と外径との間の側壁と、側壁を通って延びるアパーチャとを有する可撓性の管状構造を備えている。アパーチャは、頂点６Ｂにおいて接合されるストラット６Ａを分離し、頂点は、引張歪のレベル示す構造を有する。本発明の他の局面に従って、疲労抵抗ステントを作る工程が開示される。本発明のさらなる局面に従って、疲労抵抗ステントのための送達システムおよび使用法が提供される。【選択図】図６
