AUTOMATICALLY ADJUSTING BAND SYSTEM
First Claim
1. A restriction system for forming a restriction in a patient, comprising:
- an implantable restriction device that is adjustable and configured to form a restriction in a patient; and
an implantable pump in fluid communication with the restriction device and having a plurality of actuators configured to change shape upon the application of energy thereto such that sequential activation of the plurality of actuators is effective to create pumping action to move fluid through the pump.

Abstract
Devices and methods for forming a restriction in a patient are disclosed. In one exemplary embodiment, a restriction system is provided including an implantable restriction device, an implantable port 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 port is configured to receive fluid from a fluid source external to the patient. The implantable pump has a plurality of actuators configured to change shape upon the application of energy thereto such that sequential activation of the plurality of actuators is effective to create pumping action to move fluid through the pump.

18. A method of adjusting pressure in an implantable restriction device, comprising:
-
sensing a clinically relevant parameter; adjusting a pressure within the restriction device in response to the sensed clinically relevant parameter by activating a pump in fluid communication with the restriction device, the pump being formed of a plurality of actuators configured to change shape upon the application of energy thereto such that sequential activation of the plurality of actuators is effective to create pumping action to move fluid through the pump. - View Dependent Claims (19, 20, 21, 22, 23)

24. A pumping device, comprising:
-
a fluid conduit member having a passageway formed therethrough; and a plurality of orientation-changing actuators disposed within the fluid conduit member, each actuator being independently configurable between a normal, relaxed state in which the actuator occludes a portion of the passageway of the fluid conduit member and an energized configuration in which fluid flow is permitted between an outer surface of the actuator and an inner surface of the fluid conduit member, the actuators being configured to change orientation upon the application of energy thereto such that sequential activation of the plurality of actuators is effective to create pumping action to move fluid through the first member. - View Dependent Claims (25, 26, 27, 28)
