HYDRAULIC GASTRIC BAND WITH COLLAPSIBLE RESERVOIR
First Claim
1. An adjustable gastric band system for implantation in a body of an overweight patient, the system comprising:
- a gastric band having an inflatable member for positioning around an upper portion of a stomach of the patient;
a tube in fluid communication with the inflatable member of the gastric band, the tube having an exterior surface forming a channel thereon;
an expandable reservoir in fluid communication with the inflatable member of the gastric band, the reservoir having a collapsed configuration to facilitate implantation of the reservoir and an expanded configuration for storing a fluid to adjust the inflatable member of the gastric band; and
a protective outer sheath coupled to the reservoir, the protective outer sheath having a locking member surrounding the channel of the tube when the reservoir is in the collapsed configuration, the locking member configured to engage with the channel when the reservoir is in the expanded configuration.

Abstract
A self-regulating gastric band apparatus for adjusting stoma size. The apparatus includes an adjustable gastric band with an expandable inner ring. A band adjustment assembly includes a sensor for sensing fluid pressure in the inner ring and a pump assembly connected to the inner ring and to a controller for adjusting the volume of the fluid in the band based on the sensed fluid pressure. A memory stores an operating range of a target fluid pressure, and the pump assembly maintains the sensed band pressure within the operating range. An elongated fluid reservoir extends along part of a fill tube. An expandable fluid reservoir stores a volume of the fluid for adjusting the volume of fluid in the lumen. A protective outer sheath is provided around the exterior of an expandable fluid reservoir in both a first, deflated state, and a second, inflated state of the reservoir.
