Abstract
A tissue anchor for securing an implantable device to tissue such as soft tissue. The anchor includes a tissue-engaging portion having a tissue-engaging configuration which enhances, improves, increases, etc., the engagement, grasp, purchase, etc. of the anchor with the body tissue in which the anchor is implanted. In some embodiments, the tissue-engaging portion cinches or pinches or compresses tissue between sections of the tissue-engaging portion to grab onto or otherwise engage tissue. In some embodiments, a section of the tissue-engaging portion expands or otherwise extends away from the other portions of the anchor to increase engagement of the anchor with the tissue. In some embodiments, a section of the tissue-engaging portion may flare outwardly to drive further into tissue in a direction transverse to other portions of the anchor.
