Abstract:
1. An implant comprising: a cylindrical, collapsible anchor to be deployed within a lumen; a protrusion coupled to the anchor, the protrusion, in a constrained state, extending from an exterior surface of the anchor to penetrate tissue and, in an unconstrained state, extending further from the exterior surface of the anchor than in the constrained state, the protrusion including a first segment proximate the anchor that extends from the anchor along a first axis, and a second segment that extends from the first segment along a second axis, the first segment, in the constrained state, being collapsed against the anchor, the first axis aligned with the surface of the anchor, and the second segment, in the constrained state, extending away from the anchor; and a biodegradable constraint configured to maintain the protrusion in the constrained state until the constraint releases.
