摘要：
An implant (100) includes a collapsible anchor (102) to be deployed within a lumen and a protrusion (110) coupled to the anchor. The protrusion in a constrained state extends a distance from an exterior surface of the anchor and in an unconstrained state extends further from the exterior surface of the anchor. Also included is a biodegradable constraint such as a biodegradable tube or suture configured to maintain the protrusion in the constrained state until the constraint releases. The implant may include additional biodegradable constraints (244) each constraint configured to maintain the protrusion in a different constrained state and to degrade over a different predetermined period after the implant has been deployed within the lumen. The protrusion may include a bi-directional barb or an open loop.....
