Remotely adjustable gastric banding system
First Claim
1. An implantable system for use in a gastric band system comprising:
- a housing having a fluid inlet/outlet;
a flexible reservoir positioned within the housing and coupled to an inflatable portion of a gastric band via the fluid inlet/outlet, the flexible reservoir containing a fluid and having an expanded configuration and a contracted configuration;
a compression sheath positioned around a circumference of the flexible reservoir forming a cylinder, the compression sheath being movable to change a diameter of the cylinder;
a driving mechanism positioned around the compression sheath, the driving mechanism configured to change the diameter of the cylinder to compress the flexible reservoir from the expanded configuration to the contracted configuration, thereby causing a portion of the fluid in the flexible reservoir to move to the inflatable portion of the gastric band; and
a motor, coupled to the driving mechanism, the motor capable of actuating the driving mechanism.

Abstract
An implantable system comprises a housing that includes a flexible reservoir. The flexible reservoir is coupled to an inflatable portion of a gastric band via a fluid inlet/outlet. The flexible reservoir contains a fluid and has an expanded configuration and a contracted configuration. An access port may be coupled to the flexible reservoir and/or the gastric band to facilitate filling and draining the reservoir and/or the gastric band. A movable wall is slidably positioned around the flexible reservoir to move the flexible reservoir between the expanded configuration and the contracted configuration to move the fluid into and out of the inflatable portion of the gastric band. A driving mechanism is positioned around the movable wall and is capable of changing the size of the movable wall to compress or expand the flexible reservoir. A motor, coupled to the driving mechanism, may actuate the driving mechanism.
