Remotely adjustable gastric banding system
First Claim
1. A fluid reservoir for connecting to a remotely adjustable gastric banding system that is implantable in a patient for the treatment of obesity, the fluid reservoir comprising:
- a housing defining separately enclosed first and second coil channels;
a flexible reservoir pouch positioned within the housing and coupled to an inflatable portion of a gastric band via tubing, the flexible reservoir pouch for storing a fluid for filling and draining the inflatable portion of the gastric band;
a first receiving coil coupled to the housing and extending within the first coil channel, wherein the first receiving coil forms a first loop around the housing, and wherein the first receiving coil receives radio frequency signals from a remote transmitter to drive a pump in the remotely adjustable gastric banding system; and
a second receiving coil coupled to the housing and extending within the second coil channel, wherein the second receiving coil forms a second loop around the housing.

Abstract
A fluid reservoir for use in a remotely adjustable gastric banding system comprises a housing and a flexible reservoir pouch positioned within the housing. The flexible reservoir pouch is coupled to an inflatable portion of a gastric band via flexible tubing. A pump coupled to the flexible reservoir pouch facilitates filling and draining the inflatable portion of the gastric band. The pump may be located within or outside of the housing. A receiving coil may be coupled to the housing, and the receiving coil forms a loop around the housing. The receiving coil receives radio frequency signals to drive the pump. A circuit board may be disposed in the housing for driving the pump to move the fluid between the flexible reservoir pouch and the inflatable portion of the gastric band. A portion of the circuit board may be a flexible circuit board to allow the housing to flex.
