Abstract
A system for facilitating obesity control includes an inflatable gastric banding device, a fluid reservoir couplable to the inflatable portion, and an implantable fluid handling device coupled to the fluid reservoir and the inflatable portion. The fluid handling device includes remotely operable components housed in a biocompatible housing. The fluid handling device includes a micropump effective to pump fluid to the band and a flow sensor. The system also includes a controller/microprocessor including an algorithm programmed to automatically calibrate the pump using data from the flow sensor, prior to adjustments made to the inflation of the gastric band.

10. A method of adjusting a stoma size of a gastric banding patient having an implanted gastric band, the method comprising the steps of:
-
remotely commanding an adjustment of a volume of fluid in an inflatable portion of an implanted gastric band; calibrating a pump in fluid communication with the inflatable portion of the gastric band including initiating a sequence of operation of a pump and a pressure and/or flow sensor; and activating the calibrated pump to cause adjustment to the volume of fluid in the inflatable portion of the implanted gastric band. - View Dependent Claims (11, 12, 13, 14, 15, 16)
