Method for screening patients to predict which patients at risk of a medical disorder, such as morbid obesity, gastrointestinal problems, or gastroesophageal problems, will be responders, and conversely, which patients will not, to achieve a favorable outcome from therapy for that disorder. This method supports an intervention strategy for patients having weight or gastrointestinal problems that will cut health costs. It enables patients and care-givers alike to more efficiently use their time, efforts and resources by enabling an early selection of an appropriate treatment modality for a given patient. Its application also extends to other implantable medical devices and therapies using them.

An intragastric device inserted by endoscopic path into a patient's stomach. The device includes a balloon or envelope having a specific nominal volume. The balloon is sealingly connected to connecting elements consisting of a disc forming a support base for the balloon against an inner wall of the stomach.

Method and apparatus for treatment of morbid obesity by placement of a series of flow reduction elements in the small intestine to induce satiety are disclosed. The flow reduction elements restrict the movement of partially digested food and reduce the flow rate through the small intestine which causes the emptying of the stomach and the duodenum to occur slower. The flow reduction elements are attached to an elongated tube and are constructed from various shapes and configurations. The flow reduction elements may be inflated with fluid or may be constructed from self-expandable materials. The device is anchored in the antrum of the stomach with an anchoring member. The transoral gastric device can be inserted with a delivery catheter through the working lumen of an endoscope or alongside an endoscope and may be removed with the aid of an endoscope if desired.

Apparatus and methods for regulating the appetite of an individual suffering from morbid obesity, the apparatus including a plurality of stimulation electrodes arranged longitudinally on at least one electrode support shaft for insertion within the hypothalamus for outputting electrical discharges to specific sites within the hypothalamus.

The invention relates to the production of a vertical gastric reservoir for the surgical treatment of morbid obesity. The reservoir consists of a clamp having two plates articulated at the lower end thereof and an automatic closing system in the upper part thereof, reinforced with a sealing system. Both plates are provided with two extensions (one at each end of the instrument) on the right-hand edge thereof. Both extensions are provided with two openings that are used to fix the instrument to the stomach wall. Application of the instrument and the technical solution provided are as follows: the substitution of metal staples which are subsequently eliminated in between 15% and 20% of patients and which result in failure of the vertical band gastroplasty operation. The instrument could also be used for producing small gastric reservoirs used for gastric bypass with minor curvature instead of metal staples.
