Abstract: A remotely adjustable remotely power gastric band system may include a control device, an implant electronic device, and an implantable gastric band. The control device may telemetrically power and communicate with the implant electronic device, which may be used for adjusting the diameter of the implantable gastric band. The implant electronic device may store the gastric band adjustment history records of a patient and regulate the power received from the control device. To improve transmission efficiency, the implant electronic device may adopt a double modulation scheme for communicating with the control device. Furthermore, the implant electronic device may detect and resolve motor blockage issues related to the implantable gastric band.

Abstract: An implantable banding system for treating obesity is disclosed. The implantable banding system includes a telemetric control unit, a gastric band having at least one inner fluid compartment and an outer mechanical adjustment mechanism, the at least one inner fluid compartment being filled with a fixed volume of fluid, and the outer mechanical adjustment mechanism comprising a device configured to adjust the gastric band through a variety of diameters, an implant circuit coupled to the device and configured to receive an adjustment signal to control the operations of the device, and a sensor positioned within the at least one inner fluid compartment, configured to monitor a parameter of the fixed volume of fluid, generate an adjustment signal based on the parameter and one or more parameter control limits, and automatically activate the device based on the adjustment signal or transmit the adjustment signal to the telemetric control unit.
