Patent ID: 7828813

Claim:
A gastric band not provided with a dilatable part and made of an elastomeric material presenting a flexibility of deformability, comprising: a single-piece assembly made from said elastomeric material such that the gastric band resumes an original geometry after being deformed upon passage of food and including different successive separate zones formed on an entire length of the gastric band, said zones having two end zones shaped specifically to constitute flexible nesting and position-locking male-female parts and, between said end zones, an intermediate connecting zone of solid cross-section over a main part of a length of said intermediate connecting zone and designed to be in simple abutment on a part of a stomach to be encircled, wherein said end zones define, on a first end, a head zone provided with a curved profiled tab extending substantially perpendicularly from the length of said intermediate connecting zone and having lateral walls each with a stop face thereon, a secondary tip with a triangular flat face, and a transverse opening for passage of a draw loop and, on a second end, a rear end anchoring zone forming a main tip having a transverse opening corresponding to said transverse opening of said tab for passage of a draw loop between said openings of said main tip and said tab, said zones being adapted to integrate into each other by introduction of said main tip of said rear end anchoring zone in an opening defined between said lateral walls connecting said tab to said intermediate connecting zone.
