阅读说明：本技术 对接元件 (Butt joint element ) 是由 内塔内尔·贝尼舒 本杰明·斯宾塞 莫兰·索博尔 于 2018-03-01 设计创作，主要内容包括：描述了用于治疗具有病变二尖瓣的受试者的设备和方法。对接元件(100)被植入受试者的左心房内,使得对接元件的任何部分都不延伸穿过受试者的二尖瓣。对接元件至少部分地经由左心房的组织的向内生长而变得锚固到左心房的组织。对接元件(100)包括被植入在受试者的二尖瓣环处的环(102)和从所述环向上延伸的具有至少15mm的高度的框架(104)。在左心房的组织的向内生长发生之后,假体二尖瓣设备(20)至少部分地被放置在对接元件内部,并且至少部分地通过抵着环径向地扩张而变得锚固到对接元件。还描述了其他应用。(Devices and methods for treating a subject having a diseased mitral valve are described. The docking element (100) is implanted within a left atrium of a subject such that no portion of the docking element extends through a mitral valve of the subject. The docking element becomes anchored to the tissue of the left atrium at least in part via ingrowth of the tissue of the left atrium. The docking element (100) comprises a ring (102) implanted at the mitral annulus of a subject and a frame (104) extending upwardly from the ring having a height of at least 15 mm. After ingrowth of tissue of the left atrium occurs, the prosthetic mitral valve device (20) is placed at least partially inside the docking element and becomes anchored to the docking element at least partially by expanding radially against the annulus. Other applications are also described.)
