Annuloplasty ring with intra-ring anchoring

摘要

A method includes positioning an anchor deployment manipulator at least partially within a lumen of a sleeve of an annuloplasty ring, the sleeve having a lateral wall shaped to define the lumen, and the lumen extending longitudinally along a length of the sleeve. A portion of the sleeve that contains a distal end of the deployment manipulator is placed into an atrium in a vicinity of an annulus of an atrioventricular valve. An anchor is deployed from the distal end of the deployment manipulator through the lateral wall of the sleeve into cardiac tissue, while the distal end of the deployment manipulator is positioned such that a central longitudinal axis of the deployment manipulator through the distal end of the deployment manipulator forms an angle of between 45 and 90 degrees with the lateral wall of the sleeve at a point at which the anchor penetrates the lateral wall.

1. 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 lateral wall shaped to define the lumen, and the lumen extending longitudinally along a length 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 a plurality of anchors from the distal end of the deployment manipulator through the lateral wall of the sleeve into cardiac tissue of the subject by:
using the distal end of the deployment manipulator to bring a portion of the sleeve into contact with the cardiac tissue,thereafter, deploying one of the anchors from the distal end of the deployment manipulator through the lateral wall of the sleeve into the cardiac tissue while the deployment manipulator is positioned at a site along the annulus,thereafter, using the distal end of the deployment manipulator to bring, into contact with the cardiac tissue, another portion of the sleeve that was not in contact with the cardiac tissue during deployment of the one of the anchors, by positioning the deployment manipulator at another site along the annulus, andthereafter, deploying another one of the anchors from the distal end of the deployment manipulator through the lateral wall of the sleeve into the cardiac tissue while the deployment manipulator is positioned at the other site along the annulus.
