Abstract: A clinching or swaging fastener for securely mounting a secondary article, such as a magnet, flush to a surrounding surface. An interference fit fastening feature holds the secondary article flush by using a deformable center knob on the end wall at the bottom of the retainer. Alignment features on the outer portion of the retainer body can fixture the magnet in a desired orientation. A radial flange surrounds the mouth of the bore which has a peripheral lip that extends upwardly. Clinch attachment means comprising a circular peripheral undercut is located on the outside of the body just below the flange for attaching the body to a host object. The article may have a peripheral chamfer at the top which receives the lip as it is deformed against the article to provide a flush alignment to the host object.

Abstract: Devices and methods are disclosed for retrieving an implant or tissue anchor during the course of a percutaneous medical procedure. An implant is provided having a retrieval tether attached to it. The retrieval tether is attached to the implant on one end, and the proximal end of the tether can be threaded through an implant retrieval device. The retrieval device comprises an inner elongate body that is used to capture and secure the retrieval tether. The retrieval device also comprises an outer elongate body that may be configured to be advanced over the retrieval tether from a location remote from the implant (e.g., outside a patient's body) to contact and retrieve the implant after it has been deployed and/or implanted within a patient's body.
