Abstract: The anchoring and fixing implant is constituted by a continuous wire with rectilinear portions and curved portions. It comprises: a) a central curved portion forming a winding of substantially 1.5n turns, n being, for example, equal to 1, b) on either side and in extension of said central portion, a set of two rectilinear portions, specifically an intermediate portion and an end portion, connected to one another by a bent portion at an angle of the order of 30° to 90° . Also, the rectilinear end portions are oriented divergently so as to make an angle of the order of 60° to 180° between them. The surgical assembly comprises an implant as above, a fixing thread intended to be threaded in the central curved portion of the implant and an ancillary device.

Abstract: The gastric ring comprises an elongate element that can be deformed into a loop between a distal end portion and a proximal end portion, together with closure means suitable for folding the elongate element into a loop and for fastening the distal and proximal end portions together once they have been moved close to each other while looping the ring. At least the elongate element is made of a material that is resorbable, preferably over a period of about or less than 2 years, e.g. of a poly-?-hydroxy acid. The elongate element is constituted by a proximal link, a distal link, and intermediate links hinged about pivot axes.
