摘要： A plurality of structures that resiliently attract one another are provided for implanting in a patient around a body tissue structure of the patient. For example, the body tissue structure may be the esophagus, and the plurality of structures may be implanted in an annulus around the outside of the esophagus, the annulus being substantially coaxial with the esophagus. The attraction may be between annularly adjacent ones of the structures in the annulus, and it may be provided, for example, by magnets or springs. The array of structures is preferably self-limiting with respect to the smallest area that it can encompass, and this smallest area is preferably large enough to prevent the apparatus from applying excessive pressure to tissue passing through that area.

摘要： A digital manufacturing system for producing first and second objects comprises a platen, a gantry, a pantograph extrusion head system and first and second sets of extruders. The platen defines a workspace upon which the objects are produced. The gantry defines a headspace displaced from the workspace. The extrusion head system is mounted to the gantry for movement in the headspace. The sets of extruders are connected to the extrusion head system and are configured to deposit extrusion material on the workspace to build the objects. Each set of extruders comprises a first extruder mounted to the extrusion head system; a second extruder mounted to the extrusion head system so as to be actuatable from a first to a second position; and a flexible linkage connecting the extruders. The flexible linkages position the second extruders in approximately equal known spatial relationships to the first extruders in the second positions.
