Abstract: An anchor configured to maximize the surface area of the anchor to improve anchor retention is disclosed. The anchor may be configured with a width that differs from a thickness of the anchor. In some embodiments, the anchor be configured as a helical ribbon defining a central lumen about a central axis extending through the helical ribbon. The helical ribbon may vary in width, thickness, central lumen diameter, or a combination thereof, along its extent. The anchor may include retention features that are configured to promote tissue and/or implant interaction for improved anchor retention.

Abstract: Features for a restraint to facilitate delivery and deployment of an implantable cardiac device are described. The restraint may include a series of circumferential engagements for securing inwardly corresponding portions of the implant. The restraint may be located inside the implant and provide a radially inward force on the implant. The restraint may include a center shaft having a series of grooves configured to cooperate with corresponding splines of the implant. Distal or proximal advance of the restraint disengages the restraint from the implant. The implant may include a tubular frame configured to contract and be secured by the restraint in a contracted configuration and to expand upon disengagement from the restraint. The restraint may provide for a smaller overall cross-sectional profile of a transcatheter delivery system, for instance by negating the need for a distal delivery sheath.
