Patent number: 9192501Abstract: 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: GrantFiled: November 8, 2013Date of Patent: November 24, 2015Assignee: Apollo Endosurgery, Inc.Inventors: Pierre Fridez, Alain Jordan, Jean-Charles Montavon, Tiago Bertolote, Laurent Mosimann, Xavier Raemy, Razack Osseni, Joel Bonny

Publication number: 20140039250Abstract: Apparatus and methods are provided comprising an implantable non-hydraulic ring that encircles and provides a controllable degree of constriction to an organ or duct and an external control that powers and controls operation of the ring. The ring includes a rigid dorsal periphery that maintains a constant exterior diameter, and a compliant constriction system that reduces intolerance phenomena. A high precision, energy efficient mechanical actuator is employed that is telemetrically powered and controlled, and maintains the ring at a selected diameter when the device is unpowered, even for extended periods. The actuator provides a reversible degree of constriction of the organ or duct, which is readily ascertainable without the need for radiographic imaging. Methods of use and implantation also are provided.Type: ApplicationFiled: October 8, 2013Publication date: February 6, 2014Applicant: Allergan, Inc.Inventors: Michel Bachmann, Alain Jordan, Pierre Fridez, Jean-Charles Montavon, Christian Imbert, Nikos Stergiopulos

Publication number: 20130281772Abstract: The present invention is directed to a laparoscopic device insertion cannula (“LDIC”). The LDIC can be configured to store a surgical implant and can be formed from a hollow cylindrically shaped tube including a tapered closed tip at a distal end and a cap at a proximal end. The hollow tube can also include an opening adjacent the distal end. The opening can be covered, for example, by a flexible window. The flexible window can include a slit from which the surgical implant can be extracted from the LDIC. The surgical implant can be, for example, a gastric band.Type: ApplicationFiled: June 20, 2013Publication date: October 24, 2013Inventors: Pierre Fridez, Julien Rion, Fabien Kagi, Vernon L. Vincent

Publication number: 20130281771Abstract: The present invention provides for a gastric banding system including an adjustment system that automatically increases the size of a constricted portion of a gastric lumen in response to an obstruction passing through the gastric lumen. The size of the constricted portion of the gastric lumen increases rapidly when the obstruction approaches a gastric band constricting the lumen. The adjustment system is also configured to slowly return the constricted gastric lumen to an equilibrium size the lumen had prior to the obstruction passing through the lumen. Various embodiments of gastric banding systems and adjustment systems are disclosed.Type: ApplicationFiled: June 19, 2013Publication date: October 24, 2013Inventors: Pierre Fridez, Tiago Bertolote, Xavier Raemy, Fabian Kaegi, Julien Rion
