Annuloplasty ring with intra-ring anchoring
First Claim
1. Apparatus comprising an annuloplasty system for use on a subject, which comprises:
- an annuloplasty ring, which comprises a sleeve having a wall defining a lumen that extends longitudinally along a length of the sleeve;
a contracting mechanism, coupled to the sleeve;
a contracting member that extends along at least a portion of the sleeve and is coupled at respective locations along the contracting member to (a) the contracting mechanism and (b) a portion of the sleeve, wherein the contracting mechanism is configured to contract the annuloplasty ring by pulling on the portion of the sleeve;
at least one anchor, shaped so as to define a tissue coupling element, which tissue coupling element is shaped so as to define a longitudinal axis, and is configured to penetrate cardiac tissue of the subject in a direction parallel to the longitudinal axis; and
an anchor deployment manipulator, configured to be removably positioned within the lumen of the sleeve, and, while so positioned, to deploy the tissue coupling element from a distal end of the deployment manipulator by rotating the tissue coupling element in order to penetrate the tissue coupling element through the wall of the sleeve into the cardiac tissue in the direction parallel to the longitudinal axis of the tissue coupling element and parallel to a central longitudinal axis of the deployment manipulator through the distal end of the deployment manipulator.

Abstract
Apparatus is provided that includes an annuloplasty system for use on a subject. The system includes an annuloplasty ring, which includes a sleeve having a lumen, and at least one anchor, shaped so as to define a coupling head and a tissue coupling element, which tissue coupling element is shaped so as to define a longitudinal axis, and is configured to penetrate cardiac tissue of the subject in a direction parallel to the longitudinal axis. The system further includes an anchor deployment manipulator, configured to be removably positioned within the lumen of the sleeve, and, while so positioned, to deploy the tissue coupling element from a distal end of the deployment manipulator through a wall of the sleeve into the cardiac tissue in the direction parallel to the longitudinal axis of the tissue coupling element and parallel to a central longitudinal axis through the distal end of the deployment manipulator.

18. A method comprising:
-
positioning an anchor deployment manipulator at least partially within a lumen of a sleeve of an annuloplasty ring, the sleeve having a wall shaped to define the lumen, and the lumen extending longitudinally along a length of the sleeve, wherein the annuloplasty ring includes a contracting mechanism, coupled to the sleeve, and a contracting member that extends along at least a portion of the sleeve and is coupled at a respective locations along the contracting member to (a) the contracting mechanism and (b) a portion of the sleeve; placing, into an atrium of a subject in a vicinity of an annulus of an atrioventricular valve, at least a portion of the sleeve that contains a distal end of the deployment manipulator; and deploying at least one anchor from the distal end of the deployment manipulator, by rotating a tissue coupling element of the anchor in order to penetrate the tissue coupling element through the wall of the sleeve such that the tissue coupling element of the anchor enters cardiac tissue of the subject in a direction parallel to a central longitudinal axis of the deployment manipulator through the distal end of the deployment manipulator, wherein the tissue coupling element is shaped so as to define a longitudinal axis, and wherein deploying the at least one anchor comprises deploying the at least one anchor from the distal end of the deployment manipulator through the wall of the sleeve, by penetrating the tissue coupling element through the wall of the sleeve, such that the tissue coupling element of the anchor enters cardiac tissue of the subject in a direction parallel to the longitudinal axis of the tissue coupling element, and further comprising contracting the annuloplasty ring by actuating the contracting mechanism to pull on the portion of the sleeve. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 29, 30)
