1. An adjustable gastric implant for constraining at least a portion of a stomach, comprising:

  • an elongate member having first and second ends, the elongate member configured to engage the stomach;

    at least one actuator coupled to the first and second ends of the elongate member, wherein the at least one actuator comprises a shape memory material;

    wherein activation of at least a portion of the shape memory material results in a conformational change in the at least one actuator; and

    wherein the conformational change in the at least one actuator moves the elongate member from a first conformation to a second conformation, such that the first and second ends move with respect to each other, resulting in a change in a lumenal dimension of the stomach.
