Abstract: An implant includes a collapsible anchor to be deployed within a lumen and a protrusion 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, 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. The protrusion may be configured to penetrate a wall of the lumen and to allow tissue to grow about the protrusion.

Abstract: The present invention relates to an anchor configured for minimally-invasive implantation and sized to remain securely positioned within at least a portion of the gastrointestinal tract of an animal. The anchor includes a radial spring formed from an elongated resilient member shaped into an annular wave pattern about a central axis. The anchor defines a central lumen and provides an outward radial force, while allowing for substantial flexure about its perimeter. The anchor is generally removable, but can include fasteners, such as barbs, to further secure it to the surrounding anatomy. In some embodiments, the anchor includes a connector coupling a fixed portion to a removable portion. Further, the anchor can be used to secure a medical device within the body, such as a flexible sleeve within the intestine.

Abstract: A device and process for crystallizing a compound using hydrodynamic cavitation comprises the steps of mixing at least one stream of a feed stock solution containing the compound to be crystallized. The feed stock solution is caused to flow through the cavitation zone of a rotor-stator type hydrodynamic cavitation device. Cavitation events and resulting shock waves generated in the cavitation zone cause nucleation and the production of seed crystals within the solution. Possible recirculation of the solution through the cavitation device promotes crystallization at the sites of the seed crystals resulting in increasing larger crystals. The resulting crystalized compound can be extracted from the solution and used in product manufacturing and industrial processes. The rotor-stator design allows for high flow rates, high applied energy and robust service with minimized wear.
