Abstract
【解決手段】心臓弁の機能を改善するための機器であって、該機器は、形状記憶材料から形成される支持部材及び支持部材の方向に制限作用を加える制限部材を含む。支持部材は、前記形状記憶材料が活性化形状を取り、一方、制限部材が、支持部材の方向を制限する間、弁の環状口の形状に合致して弁の一側に当接してもよい。制限部材は、支持部材が、所定の方向に形状が変化することを可能とするために取り外しが可能である。制限部材は、患者の体内において分解されるように生物分解性であってもよいし、あるいは、引き抜きされるように、支持部材から脱離可能となっていてもよい。さらに他の実施態様による支持部材は、支持部材の長さの縮小と関連して断面の増大が起こる形状変化を提示する。さらに別の実施態様による支持部材は、第1および第2活性化形状を有する。
