Anchoring of prosthetic valve supports
First Claim
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, disposed within the channel, and slidable through at least part of the channel; and
an anchor driver, disposed 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.

Abstract
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.

12. 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, having a delivery configuration in which the upstream support portion is rolled up, defines a channel having a central longitudinal axis, and is configured to be disposed within the delivery tube, and being configured to be transitioned from the delivery configuration to the working configuration by being unrolled; a tissue anchor, configured to be disposed within the channel, and slidable through at least part of the channel; and an anchor driver, 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 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.

13. 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, and having 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, 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 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, wherein; in the delivery configuration, the upstream support portion has a distal portion and a proximal portion, and the channel is defined between the distal portion and the proximal portion, the anchor comprises a first anchor, and the anchor driver is configured to anchor the distal portion of the upstream support portion to the tissue by driving the first anchor through the distal portion of the upstream support portion, and the apparatus is configured such that; the proximal portion of the upstream support portion is configured to be at least partly exposed from the delivery tube subsequently to the anchoring of the distal portion, and the apparatus further comprises a second anchor, configured to be driven through the proximal portion of the upstream support portion and into the tissue subsequently to the exposing.
