Estimating the term…
The invention relates to a prosthetic device intended for being implanted in a patient's gastrointestinal tract, said device comprising: an inflatable gastric balloon, the volume of which is modulatable; a duodenal prosthesis comprising a pre-pyloric flange and a flexible tubular body. According to the invention, such a device is characterized in that it comprises a system for coupling said balloon to said duodenal prosthesis; said duodenal prosthesis is compressible and expandable in a radial direction; said prosthesis has a wall that is fixedly attached, on at least one part of its length, to a helical frame and said helix has an irregular pitch.
Prosthetic device to be implanted in a patient's gastrointestinal tract, said device comprising:
Device according to one of the preceding claims, wherein the duodenal prosthesis (3) is without hooks.
Device according to one of the preceding claims, wherein the system (2) for coupling comprises means (22) of irreversible fixed attachment means.
Device according to one of the preceding claims, wherein said helical frame (33) extends on a portion of the total length of the duodenal prosthesis ranging from 50% to 85%, preferably 75%.
Device according to one of the preceding claims, wherein said modulatable gastric balloon (1) and/or the duodenal prosthesis (3) are constituted entirely or partly by a biocompatible material, such as silicone, polyurethane, nylon, polyvinyl chloride, urethane, polyamide, polyester, or the combination of at least two of these materials.
Device according to one of the preceding claims, wherein said helical frame (33) is made of a biocompatible metallic material, preferably an alloy of nickel and titanium.
Device according to one of the preceding claims, the gastric balloon (1) comprises an inflating catheter (4).
