摘要：
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.
