Implantable weight control device to promote early and prolonged satiety in a bariatric patient

A weight control device that is endoscopically implantable in a patient to promote early and prolonged satiety in the patient, the weight control device comprising:

• an elongated internal module having a gastric portion, a duodenal portion with a distal end, and an intermediate portion positioned between the gastric and duodenal portions, the internal module also having a central lumen extending through the gastric, duodenal and intermediate portions;
• a valve body assembly connected to a gastric end of the internal module, the valve body assembly having (i) a central aperture, (ii) a first set of an inflation valve and a deflation valve and (iii) a second set of an inflation valve and a deflation valve, wherein said first and second sets of valves are arranged radially about the central aperture;
• an inflatable member that receives the internal module and that is joined to only (i) the valve body assembly, (ii) the intermediate portion of the internal module and (iii) the distal end of the internal module;
• wherein when the inflatable member is supplied with a working fluid (i) a gastric bulb is formed in the inflatable member, said gastric bulb residing between the valve body assembly and the intermediate portion of the internal module, and (ii) a duodenal bulb is formed in the inflatable member, said duodenal bulb residing between the intermediate portion of the internal module and the distal end of the internal module;
• wherein the valve body assembly and the internal module include both a first inflation passageway and a first deflation passageway for the transport of the working fluid to the gastric bulb to allow for selective inflation of the gastric bulb, wherein the gastric bulb forms a partial gastric outlet obstruction when the weight control device is implanted in the patient;
• wherein the valve body assembly and the internal module include both a second inflation passageway and a second deflation passageway for the transport of the working fluid to the duodenal bulb to allow for selective inflation of the duodenal bulb, wherein the second inflation and deflation passageways extend through the gastric and intermediate portions of the internal module to reach the duodenal portion of the internal module;
• and,
• wherein the central lumen of the internal module and the central aperture of the valve body assembly are cooperatively aligned to provide an internal passageway extending through the weight control device that receives and allows for the passage of chyme from the patient's stomach through the device to the duodenum.
