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.
