Inflatable and adjustable gastric band for treating obesity
First Claim
1. An inflatable and adjustable gastric band to be positioned around a segment of the digestive tract in order to narrow said segment, said gastric band comprising:
- a hollow flexible band, which is resilient and comprises an inner wall and an outer wall defining an inflatable leaktight chamber with an inflation opening;
a flexible inflation tube whose distal end is connected to the inflation opening of the band, and whose proximal end is intended to be connected to inflation means;
the tube and the band being provided, in respective distal end areas thereof, with complementary closure means and that are able to mutually engage so as to lock a ring in a closed position, said ring being formed by bringing a distal end and a proximal end of the band together;
the closure means of the tube being at least one notch and the closure means of the band being at least one loop, such that the proximal end of the tube is configured to be engaged through the at least one loop of the band as far as a locked closure position once said at least one notch is brought beyond said at least one loop;
whereinthe hollow flexible band, when not in use and when the tube and the band are not engaged in each other to form the ring, has a preformed curved part which extends starting from a proximal end area thereof and which is continued via a substantially rectilinear part to the distal end of the band, said substantially rectilinear part has a length between 10 and 40% of the total length of the hollow flexible band for facilitating the engagement of the proximal end of the tube through said at least one loop of the band, andsaid at least one loop being arranged on an outer wall of the substantially rectilinear part of the hollow flexible band.

Abstract
An inflatable, adjustable gastric band includes a flexible, hollow, resilient band; and a flexible inflation tube connected to the band and complementary closing means that are capable of mutually engaging so as to lock a ring in a closed position. The ring formed by bringing the distal end and the proximal end of the band together into a slipknot. The hollow band has, in an inoperative position, a preformed curved portion which is extended, by a substantially rectilinear portion, from the proximal end area thereof to the free distal end of the band. The substantially rectilinear portion being suitable for facilitating the insertion of the proximal end of the tube through the loop(s) of the band, and in that the hollow band has, on the outer wall thereof, two loops, said loops being arranged on the substantially rectilinear portion of the hollow band.
