A medical device for clamping the stomach in morbid obesity surgery
consists of a silicone frame that is essentially U-shaped, having
opposing legs self-hinged to a bight portion interconnecting the legs.
The opposing legs have sufficient stiffness to permit limited bending and
have inner surfaces that sealingly carry an inflatable balloon which can
be selectively inflated or aspirated after the device has been clamped to
the stomach to adjust the gastric restriction stoma. A flexible latch
member carried by one of the legs has at least one serration which is
inserted into a latch cavity of the opposing leg to lock the opposing
legs in fixed spaced relationship. Lumens within the legs communicate
with a fluid supply source and respective inflatable balloon for
selective inflation or aspiration of the inflatable balloons.
