Abstract
Described herein are devices and methods for delivering implants that have multiple coupled anchors. The anchors have an elongate form following a curved arcuate path in a single turning direction. Each anchor has two legs arranged to diverge away from each other, where each leg has a substantially non-constant radius of curvature and a substantially straight distal tip. 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. One variation of a multi-opening guide tunnel has releasable retention flaps and an aperture capable of deploying a fluid contrast medium into a patient without interfering with anchor delivery.
