摘要：
PROBLEM TO BE SOLVED: To provide an artificial valve ring which can be deformed according to a shape of a valve cusp or annulus of a patient during surgical operation.SOLUTION: An artificial annulus 1 composed of a deformable thermally conductive member 10 and a thermally plastic resin, includes: a shape maintaining member 20 provided so as to cover the thermally conductive member 10 or be covered with the thermally conductive member； and a membrane 30 provided so as to cover the shape maintaining member 20 or the thermally conductive member. The shape maintaining member 20 is softened to be deformable by the heated thermally conductive member 10, which is cooled and hardened in a predetermined shape to maintain the shape.SELECTED DRAWING: Figure 2【課題】手術中に患者の弁尖、弁輪の形状に応じた形状に変形させることが可能な人工弁輪を提供する。【解決手段】人工弁輪１は、変形可能な熱伝導部材１０と、熱可塑性樹脂から構成され、熱伝導部材１０を覆って、或いは、熱伝導部材で覆われ配置される形状保持部材２０と、形状保持部材２０或いは熱伝導部材を覆って配置される皮膜３０と、を備える。加熱された熱伝導部材１０により形状保持部材２０が軟化して変形可能となり、所定の形状に成形されて冷却された後、硬化して成形された形状を保持する。【選択図】図２
