An exemplary implantable prosthetic device has a coaption element and at least one anchor. The coaption element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaption element can have a structure that is impervious to blood and that allows the native leaflets to close around the coaption element during ventricular systole to block blood from flowing from the left or right ventricle back into the left or right atrium, respectively. The coaption element can be connected to leaflets of the native valve by the anchor. 示例性可植入假体装置具有对合元件和至少一个锚固件。对合元件被配置以定位在天然心脏瓣口内，以协助填充天然瓣膜反流空间和形成更有效的密封。对合元件可具有血液不可透过并且允许天然小叶在心室收缩期间在对合元件周围闭合以阻止血液分别从左心室或右心室回流到左心房或右心房中的结构。对合元件可通过锚固件连接至天然瓣膜的小叶。
