ANCHORING OF PROSTHETIC VALVE SUPPORTS

摘要

Apparatus is provided, including: (1) a delivery tube, transluminally advanceable to the heart of the subject; (2) a prosthetic valve support, configured to support a prosthetic valve at a native valve of the heart, and including an upstream support portion, the upstream support portion: (A) having a working configuration in which it is generally annular and (B) having a delivery configuration in which it defines a channel, and is configured to be disposed within the delivery tube; (3) a tissue anchor, slidable through the channel; and (4) an anchor driver. The anchor driver is slidable within the delivery tube and the channel, and configured to anchor the upstream support portion to tissue of the heart by driving the tissue anchor through the upstream support portion and into the tissue, while at least part of the upstream support portion is disposed within the delivery tube.

1. Apparatus for use with a prosthetic valve at a native valve of a heart of a subject, the apparatus comprising:
a delivery tube, transluminally advanceable to the heart of the subject; a prosthetic valve support, configured to support the prosthetic valve at the native valve, and comprising an upstream support portion, the upstream support portion:
having a working configuration in which the upstream support portion is generally annular and has (1) a tissue-contacting side configured to be placed against an atrial surface of the native valve, and (2) an opposing side, and defines an opening therebetween, andhaving a delivery configuration in which the upstream support portion defines a channel having a central longitudinal axis, and is configured to be disposed within the delivery tube; a tissue anchor, configured to be disposed within the channel, and slidable through at least part of the channel; and an anchor driver, slit able within the delivery tube and the channel, and configured to anchor the upstream support portion to tissue of the heart by driving the tissue anchor from the opposing side through the upstream support portion and into the tissue, while at least part of the upstream support portion is disposed within the delivery tube.
