摘要:
Methods and devices for effecting a gastric restriction system are disclosed. In one exemplary embodiment, a restriction system for forming a restriction in a patient is provided and can include an implantable restriction device and at least one implantable sensor that is in communication with the restriction device. In general, the implantable restriction device can be adjustable and can be configured to form a restriction in a patient. The implantable sensor(s) can be defaulted to a dormant power usage mode and can have a triggering mechanism that is configured to place the sensor(s) in a use configuration upon the occurrence of a triggering event.
摘要:
A method for regulating hormone production comprises placing at least one electrode in a gastrointestinal tract of a patient and recording an electrical signal during a preselected event produced by the gastrointestinal tract. The method further involves the steps of storing the electrical signal, and playing back the electrical signal by activating the electrode during the absence of the preselected event.
摘要:
Various powering devices are provided for transferring and/or generating energy from numerous sources to a communicating member implanted in a patient. The energy transferred to or generated by the communicating member can be used to provide power to an implantable restriction system configured to form a restriction in a pathway.

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:
An implantable restriction device can be configured to provide a restriction in a patient, for example as a function of the pressure of fluid. The implantable restriction device can include one or more sensors configured to sense a variety of parameters, such as pressure of the fluid within the implantable restriction device, pulse width, pulse amplitude, pulse count, pulse duration, or frequency, electrical characteristics, or other parameters. Data obtained by the one or more sensors (for example, the data representing pressure, pulse characteristics, and so on) may be communicated to a device located external to the patient, such as a data logger, using telemetry coils or other communicators. The data logger may store the data, and may communicate the data to a remote location via a network such as the Internet. A docking station may be provided to couple the data logger to a network and/or to recharge a cell in the data logger. The logged data may be analyzed and/or displayed using a variety of techniques to assess and/or track the condition of the restriction device or of the patient, to monitor patient physiology, or for other purposes.

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.
