Publication number: 20110270025Abstract: 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.Type: ApplicationFiled: March 30, 2011Publication date: November 3, 2011Applicant: ALLERGAN, INC.Inventors: Pierre Fridez, Alain Jordan, Jean-Charles Montavon, Tiago Bertolote, Laurent Mosimann, Xavier Raemy, Razack Osseni, Xuan Mai Tu, Joël Bonny
