1. A passive intragastric obesity treatment implant, comprising:

  • a series of non-inflatable members each having a through bore, each of the members having a male and a female mating connector which permits each member to connect with another member, each of the members being sized such that it can be easily implanted and removed through the esophagus, the members together capable of taking up volume within the stomach of at least 400 ml and being made of a material that will resist degradation over a period of at least six months within the stomach; and

    a tether sized to pass through the through bores of the non-inflatable members, a distal end of the tether attaching to a distal one of the non-inflatable members such that the members can be pulled together by pulling the tether taut to cause the male and female mating connectors to couple, thus forming a relatively solid structure, wherein the male and female mating connectors of the members are configured such that the relatively solid structure formed after pulling the tether taut is a non-straight shape, and wherein adjacent non-inflatable members in the series include features that cause the adjacent non-inflatable members to couple with each other in a predefined orientation relative to each other and without being able to move freely relative to one another.
