Abstract: Disclosed herein are devices and methods for assessing the surface of a target cardiac tissue and for delivering a tissue anchor to cardiac tissue at a preselected depth within the myocardium in a beating heart procedure. In one variation, an anchor delivery device comprises an elongate body, a tissue anchor disposed within a first longitudinal lumen of the elongate body, and a tissue depth indicator slidable within a second longitudinal lumen of the elongate body. The tissue depth indicator has a first configuration that indicates the boundary of the surface of the target tissue and a second configuration that indicates when the distal tip of the elongate body has been advanced to a preselected depth into the target tissue. In some variations, a tissue depth indicator may also be configured to resist or limit the penetration of the delivery device into tissue after a preselected depth has been reached.

Abstract: Described herein are devices and methods for delivering implants that include multiple coupled anchors. The anchors are secured to tissue using a multi-opening guide tunnel that is configured to releasably retain one or more portions of the implant located between two of the anchors. The releasable retention of one or more intervening portions of the implant maintains the position of the implant and the guide tunnel until the implant is secured to the tissue. The multi-opening guide tunnel permits securement of the multiple anchors without requiring repositioning of the guide tunnel for each anchor.
