Abstract

The invention relates to a non-inflatable gastric band (1) including two end areas (2, 3) and an intermediate portion (4). The inner surface (I) of the band (1) is intended to contact the stomach. The end areas (2, 3) are provided with complementary closing means (5, 6) selected from notches (5) and locking loops (6) that are mutually engageable so as to ensure that the band (1) is locked in a closed position. The end area (2) has at least one notch (5) and is intended to be inserted through at least one locking loop (6) placed on the outer surface of the end area (3) up to a locked closed position, wherein at least one notch (5) is moved beyond a locking loop (6). The end area (3) also includes a guide loop (7).

Claims19

Dependent claims

Non-inflatable gastric band made in one piece of molded elastomer, the gastric band comprising an end area with notch(es), an end area with loop(s), and an intermediate portion with a solid cross section situated between the two end areas, the gastric band having an inner surface-linked to an outer surface of the gastric band by two edges and wherein the inner surface is intended to come into contact with a part of a stomach encircled by the gastric band,

the two end areas being equipped respectively with complementary closing means capable of cooperating with each other in order to ensure a locking in a closed position of the gastric band, the closing means of the gastric band including at least one notch on the end area with notch(es) and at least one locking loop on an outer surface of the end area with loop(s), the at least one locking loop being integral with the end area with loop(s), wherein the end area with notch(es) is intended to be inserted through the at least one locking loop arranged on the end area with loop(s) up to the locked closed position in which the at least one notch is moved beyond the at least one locking loop, the end area with notch(es) including a terminal tongue arranged substantially in a plane of the gastric band between parallel longitudinal edges, and at least two adjacent enlarged portions projecting with respect to the longitudinal edges of the terminal tongue, each of the adjacent enlarged portions having a width measured in a plane of the gastric band, the at least one notch being formed between the at least two adjacent enlarged portions,
wherein the end area with the loop(s) also comprises at least one guide loop arranged on the outer surface of the end area with loops(s) and integral with the end area with loop(s), the at least one guide loop defining a passage for the at least one notch, the at least one guide loop forming of an arch having dimensions that are too large to allow an anti-reverse locking of the at least one notch, and greater than dimensions of a passage defined by the at least one locking loop, the at least one guide loop having a width equal to the width of the at least two adjacent enlarged portions, the at least one guide loop being closer to a free end of the end area with loop(s) than the at least one locking loop, so that during closing and locking of the gastric band, the at least one notch passes through the at least one guide loop before passing through the at least one locking loop.
