    • Apparatus for reducing mitral regurgitation, including a bendable elongated body adapted to be inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the elongated body being adjustable between a first configuration adapted to be delivered into the coronary sinus and a second configuration adapted to exert a force onto the posterior annulus. The body includes a flexible spine having a proximal end and a distal end, and a flexible wire mounted on the spine and having a distal end fixed to the spine proximate to the distal end of the spine, and having a proximal portion extending from the proximal end of the spine. Axial movement of the wire causes a change in the spine from the first configuration to the second configuration to exert the force on the posterior annulus and thereby reduce mitral regurgitation.
    • 用于减少二尖瓣反流的装置,包括适于在二尖瓣后叶附近插入到患者的冠状窦内的可弯曲的细长体,所述细长体在适于被递送到冠状动脉的第一构型之间是可调节的 窦和适于向后环施加力的第二构造。 主体包括具有近端和远端的柔性脊柱和安装在脊柱上的柔性线,并且具有靠近脊柱远端固定到脊柱的远端,并且具有从近端延伸的近端部分 脊柱结束。 线的轴向运动导致脊柱从第一构型到第二构型的变化,以将力施加在后环上,从而减少二尖瓣反流。
