摘要:
Methods of deploying and securing a heart valve prosthesis are disclosed. A heart valve prosthesis (100) having a plurality of anchor guides (212) is loaded within a catheter-based delivery device, wherein each of the anchor guides is releasably engaged by a respective elongate member (338) and wherein tensioning of the elongate members aids in collapsing the prosthesis during loading. The delivery device is advanced via a transcatheter procedure to position the heart valve prosthesis at an implantation site. The heart valve prosthesis undergoes controlled deployment by controlling the release of tension on the elongate members. After deployment of the heart valve prosthesis, an anchor tool (660) is advanced along a guide member to the anchor guide positioned at a securement site. When the securement site is reached, an anchor clip (662) is released from the anchor tool to secure the prosthesis to the heart.
