A medical device may include an implantable device for treating a body tissue structure. The implantable device may include a wire structure which may include a wave pattern. The wire structure may be elastic so as to provide a pressure around the body tissue structure such that the pressure may change with movement of the body tissue structure.

Disclosed are embodiments of an apparatus and system for performing a sleeve gastrectomy. The apparatus can include a bougie for insertion into an interior of a stomach, the bougie having a proximal bougie end and a distal bougie end, an inflation lumen having a proximal lumen end and a distal lumen end, the inflation lumen extending from the proximal bougie end through the distal bougie end, a fluid delivery system coupled with the proximal lumen end, the fluid delivery system being operably configured to deliver positive pressure in a predetermined positive pressure range into the stomach, and a monitor coupled with the proximal lumen end operably configured for the monitoring of pressure or volume within the stomach. The bougie can be operably configured to define a resection line for the sleeve gastrectomy when the predetermined positive pressure range is achieved within the stomach

An obesity treatment apparatus comprises at least one operable stretching device (10) implantable in an obese patient and adapted to stretch a portion (12a) of the patient's stomach wall (12), and an operation device (16, 18) for operating the stretching device when implanted to stretch the stomach wall portion such that satiety is created.

A medical device has an artificial contractile structure including at least one contractile element adapted to contract a hollow body organ in such a way that said contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with the contractile element constricting the hollow body organ and the resting position being defined with the contractile element not constricting the hollow body organ. The medical device further includes a tensioning device adapted to apply a force so as to tighten the contractile element around the hollow body organ, the tensioning device having a flexible transmission with a tensioning element arranged in a sheath. The sheath has an inner coiled wire coiled in a first direction, and an outer coiled wire surrounding the inner coiled wire and coiled in a second direction opposite to said first direction.

A device for wrapping around a bodily organ and preventing overexpansion thereof. The device comprises inner and outer surfaces with a pliant material located therebetween. The inner surface defines a passage and accommodates and reinforces a bodily organ. The bodily organ, following surgical implantation, extends through the passage and is surrounded by the device. The inner surface, in an uncompressed/slightly compressed state, defines a normal state which supports the bodily organ and permits flow of bodily material therethrough. As the bodily organ expands, due to the bodily material flowing therethrough, the inner surface and the pliant material are compressed and, in turn, correspondingly exert a collapsing force, against the outer wall of the bodily organ, which limits and opposes the expansion of the bodily organ and forces the outer wall of the bodily organ back toward its normal state which still permits flow of bodily material through the bodily organ.

A method for modifying the eating behavior of a patient equipped with a gastric restriction apparatus includes the steps of: a. providing an adjustable gastric band (AGB); b. providing a pressure sensor to measure pressure within the AGB; c. providing a processing unit containing instructions to collect a set of pressure measurement and to analyze the set pressure measurement; d. providing a data base comprising data concerning pressure exerted within the AGB by a bolus of liquid food, a bolus of semiliquid food, and a bolus of solid food; e. recording the sets of pressure measurements; f. recording the results; g. communicating the results; h. placing the AGB in position; i. measuring the pressure within the AGB; j. using the distinction of the current eating pattern to modify the eating behavior of the patient.

A gastroscopic method and instrument for treating obesity of a patient, using a device adapted to stretch a part of the stomach wall of said patient. The method comprises the steps of: inserting the device into the stomach through the esophagus, placing the device in contact with the stomach wall, and fixating the device to the stomach wall such that the device can stretch a part of the stomach wall.

Intestinal devices and methods for facilitating weight loss. In at least one embodiment of a method of patient treatment of the present disclosure, the method comprises the step of positioning a device, that is configured to reduce or limit localized intestinal distension, around a portion of an intestine of a patient.

A method of coordinating positioning signaling includes: sending, from a user equipment (UE), a request wirelessly for positioning service; receiving, at the UE, an indication of UE positioning signal times for sending UE positioning signals; and sending, from the UE, the UE positioning signals at the UE positioning signal times.
