In one embodiment, a pressure sensing system is described which transmits da ta to a patient management system external to a patient. The pressure sensing system can rigidly couple to an implantable port or flexibly couple to an implantable port. In some embodiments, the pressure sensing system communicates with a hydraulic actuating system. In some embodiments, the pressure sensing system is implantable and comprises a circuit capable of wireless transmission through the skin of a patient to an external receiver which is part of a patient management system. A patient management system is described which receives up to date as well as historical data from the pressure sensing system and manages the these data in the context of a patie nt database. In some embodiments, an extragastric balloon is described in which the balloon is contoured to -..it ..i poi.jL.upsilon..pi. o~ the stomach nur not circumscribe the stomach. In some embodiments, electroactive polymers or nitinol structures are utilized to create restriction on the stomach in response to food boluses entering the stomach. In some embodiments, a nasogastric connector is described with two expandable structures translateable toward and away from one another so as to create pressure between two organ lumens when brought toward each other and fixed with respe ct to one another.
