Tissue anchor

摘要

A tissue anchor has a body, protrusions from the body, and a tissue engaging fin. The body is oriented on a longitudinal axis and has a leading tip, a leading end portion extending from the leading tip, a trailing end portion connected to the leading end portion, with the trailing end portion terminating in a trailing tip that is located opposite of the leading tip. A first anchor width measured between the protrusions is greater than a second anchor width measured at the trailing end portion of the body. The tissue engaging fin is integrated with the leading end portion of the body and oriented in a direction perpendicular to the radial direction of the first and second protrusions. The tissue engaging fin has a fin width and is provided with an eyelet formed through the fin width. A gripping tab is removably attached to the tissue engaging fin.
