US 2014/0207231 A1 · ANCHORING OF PROSTHETIC VALVE SUPPORTS

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.

Dependent claims

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, 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.

4 more elements

A method for anchoring a prosthetic valve support to a native valve of a heart of a subject, the native valve having an annulus and a plurality of leaflets, the prosthetic valve support comprising an upstream support portion that is configured to be placed against an atrial surface of the annulus, the method comprising:

transluminally advancing, to the heart of the subject, the upstream support portion, while the upstream support portion (1) is in a delivery configuration thereof in which the upstream support portion has a distal portion and a proximal portion, and defines a channel therebetween, and (2) is disposed within a delivery tube;
advancing, out of a distal end of the delivery tube, the distal portion of the upstream support portion;
using an anchor driver at least a distal end of which is disposed within the channel, anchoring the distal portion of the upstream support portion to a site of the annulus by driving an anchor through the distal portion of the upstream support portion and into the site;
and
subsequently, facilitating transition of the upstream support portion into a working configuration in which the upstream support portion is generally annular, and is disposed against the annulus.

2 more elements

transluminally advancing, to the heart of the subject, the upstream support portion, while the upstream support portion (1) is in a delivery configuration thereof in which the upstream support portion generally defines a tube that defines a channel, and
(2) is disposed within a delivery tube;
advancing, out of a distal end of the delivery tube, a distal portion of the upstream support portion in the delivery configuration thereof;
anchoring the distal portion to a first site of the annulus using an anchor that is reversibly coupled to an anchor driver, by moving the anchor driver distally within the channel of the tube defined by the upstream support portion;
and
facilitating unrolling of the upstream support portion into a deployed configuration in which the upstream support portion is generally annular, and is disposed against the annulus.
