    摘要: 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.

    摘要: Methods and devices are provided for gathering impedance data related to implantable restriction devices. In general, the methods and devices can enable patients, health care providers, and others to use gathered data as a feedback mechanism to non-invasively monitor efficacy of an implantable restriction device in a patient and to identify, modify, and/or prescribe a treatment plan for the patient considering the gathered data. Impedance data can be gathered and analyzed for tissue proximate to the restriction device, e.g., a fat pad between a gastric band and the patient's stomach. Electrodes in contact with the tissue can measure an impedance of the tissue, with the impedance between the electrodes changing as the tissue reduces in size (e.g., as fat cells shrink) and/or changes configuration.

    摘要: Methods and devices are provided for handling data in an implantable restriction system. In general, the methods and devices allow collection, analysis, storage, and transmission of pressure measurements. Pressure measurement data can be compressed before storing it. Additionally, not all pressure data need be recorded or retained, such as data substantially equaling a resting or nominal pressure of an implantable restriction device indicative of little to no pressure variation and data indicative of isolated, non-recurring events. Any pressure measurement data that is recorded can be transmitted to an external device using power telemetrically provided by the external device.
