Abstract: The invention consists of the use of hydrophilic polymers or copolymers of the polyacrylic acid or sodium polyacrylate family, which are crosslinked, in proportions of between 50 and 10 000 parts per million, for the production of a rodenticidal product. The rodenticidal product is composed of polymers or copolymers as mentioned above and of an appetizing coating according to respective proportions of from 1% to 50% by weight for the polymer and from 99% to 50% by weight for the appetizing composition. The process comprises the steps consisting in mixing the abovementioned polymers or copolymers with an appetizing product so as to form a paste, then in using an extruder to form the product.

Abstract: The invention relates to a device for the treatment of obesity or excess weight of a domestic or pet mammal, the device consisting of a balloon which is adapted to be placed in the animal's stomach and comprises a flexible envelope (E) sealed against air and alimentary and/or physiological liquids, as well as an inflating valve (V) hermetically sealed to the flexible envelope (E). The invention also relates to the use of a flexible envelope (E) sealed against air and alimentary and/or physiological liquids and equipped with an inflating valve (V) to form a device for the treatment of obesity or excess weight of a domestic or pet mammal, this device being designed to be placed in this animal's stomach and filled in-situ with fluid.

Abstract: This invention relates to an assembly comprising an intragastric balloon (101) and inflation needle (125), said balloon comprising a flexible pouch (102) that is airtight and impermeable to food liquids or physiological fluids, as well as an inflating valve (111) made of elastomer, one end of which (112) is accessible from the outside of the balloon while the opposite end the opposite end (113) is located inside the balloon, and comprises: a channel (117), open at the exterior end, for receiving an inflation needle, an inflation channel (118) open at the interior end and coaxial with the reception channel, and a septum (119) separating the reception channel from the inflation channel. The reception channel and the inflation needle are adapted, by relative configuration, in order that, when the inflation needle is inserted into the reception channel without being inserted in the septum (19; 119), the inflation needle is held in place in the reception channel.
