    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 predicting performance of a restriction system for a patient. In general, the methods and devices can allow detection and prediction of a trajectory of a particular patient attribute, such as weight loss. Using previously gathered data values, data values defining a future outcome can be predicted and compared with a desired future outcome. If the future outcome deviates from the desired future outcome, one or more corrective actions can be suggested to a patient and/or a health care provider to help align the patient's treatment plan with the desired future outcome rather than the currently predicted future outcome.

    摘要: Various methods and devices are provided for aligning an internal antenna with an external device. In one embodiment, an implantable restriction system is provided and includes an implantable restriction device configured to form a restriction in a pathway, and an implantable housing associated with the implantable restriction device. The housing has at least one antenna that can be configured to communicate telemetrically with a transceiver regardless of a rotational orientation of the housing about an axis. The at least one antenna can extend along an axis aligned with the longitudinal axis of a catheter extending from the housing. In one embodiment, the implantable housing can contain a sensor that can be configured, for example, to measure at least one of a system parameter and a physiological parameter, and the antenna can be effective to communicate the measured parameter to the transceiver.

    摘要: Methods and devices are provided for diagnosing performance of a gastric restriction system. In general, the methods and devices can enable patients, health care providers, and others to use pressure data as a feedback mechanism to monitor efficacy of an implantable restriction device and to identify, train, and/or prescribe treatment plan options. Pressure data monitoring can be used locally and/or remotely to monitor a restriction in a patient and compare gathered pressure data with a typical pressure of the restriction. Based on the results of the comparison, possible problems related to the patient and the restriction can be identified and diagnosed with possible cause(s) and solution(s). Notice of any detected possible problems, causes, and/or solutions can be provided to a user.
