PROBLEM TO BE SOLVED: To provide an apparatus and a method for forming a restriction in a patient. SOLUTION: In one exemplary embodiment, a restriction system is provided. The restriction system includes an implantable restriction device, an implantable part in fluid communication with the implantable restriction device, and an implantable pump in fluid communication with the restriction device. In general, the implantable restriction device is adjustable and configured to form a restriction in a patient, and the implantable part is configured to receive a fluid from a fluid source external to the patient. The implantable pump includes a plurality of actuators configured to change shape upon application of energy thereto such that sequential activation of the plurality of actuators is effective to create pumping action to move the fluid through the pump.
