Abstract: A capsule configured for collecting samples in the intestine, comprising a body delimiting at least one compartment for receiving samples and comprising at least one opening for samples intake, and a mobile mechanism for opening and/or closing the opening controlled by the dissolution of a material which is dissolvable in the intestine.

Abstract: The device, that can be implanted in the intestinal cavity, comprises a reactor comprising a semi-permeable or porous membrane or coating linked to a element for attachment to an intestinal or gastric wall. The reactor can be in the form of a ribbon, a structure having more than two faces or an open structure delimiting a lumen, comprising, or formed from, a semi-permeable or porous membrane. The reactor can also delimit, at least partially with the semi-permeable or porous membrane of same, a closed inner space. The reactor can comprise or carry enzymes or micro-organisms, in particular bacteria or yeast. The reactor is used for generating a chemical reaction with one or more molecules present in the intestine, or for producing one or more biologically active molecules. It can, in particular, be used for consuming sugars, disaccharides and simple sugars or producing essential amino acids or other molecules having a positive effect on the health.

Abstract: The application relates to a device for collecting a sample of intestinal fluid comprising a polymeric inner material having an at least partially compressed open cell structure, having a volume Vi and being suitable for swelling to a volume greater than or equal to 1.1×Vi by absorbing intestinal fluid, said material being encased with an elastic polymeric casing impervious to digestive fluid, said casing comprising at least one opening allowing the intake of intestinal fluid into the inner material, a gastro-resistant material suitable for dissolving in intestinal fluid at 37° C. being disposed on top of each opening, and at least one mechanism for closing the opening(s).

Abstract: The system has a plurality of dishes (1) for receiving at least one sample, each dish having a perforated base (2) enabling liquid reagents or solutions to pass continuously therethrough, the dishes being superposed in a confining tube (5); a circuit (50) for the continuous outflow of the solutions originating from distinct reservoirs (17); a multipath electrovalve (15); an electric pump (13); and a member for controlling and commanding the pump (13) and the multipath electrovalve (15) in a sequential and coordinated manner.
