The elongated body is generally sinusoidal shaped with at least one tissue engaging surface oriented such that a needle will pass therethrough. The elongated body also includes at least one needle passing channel respectively formed adjacent the at least one tissue engaging surface. The at least one needle passing channel generally passes through the center of the sinusoidal waveforms defined by the at least one tissue engaging surface such that a needle will pass entirely through stomach tissue contacting the tissue engaging surface of the elongated body. The elongated body further includes a suture passing channel.

Methods and devices are provided for predicting performance of a restriction system for a patient. In general, the methods and devices can allow detection and prediction of a trajectory of a particular patient attribute, such as weight loss. Using previously gathered data values, data values defining a future outcome can be predicted and compared with a desired future outcome. If the future outcome deviates from the desired future outcome, one or more corrective actions can be suggested to a patient and/or a health care provider to help align the patient's treatment plan with the desired future outcome rather than the currently predicted future outcome.

Gastric restriction device implants and their use in controlling body weight are described. In some embodiments, activation of a shape memory material drives an actuator coupled to an implant, resulting in a conformational change in the implant. In some embodiments latch and ratchet mechanisms operate incrementally to increase or decrease a size of a stomal opening produced by the gastric restriction device. Methods are described by which adjusting the size of the stomal opening is used to restrict the rate at which food passes through the stomach.

Methods and devices are provided for adjusting the height of devices in a gastric restriction system. In general, the methods and devices allow one or more implantable housings coupled to an implantable restriction device to have an adjustable height. The housing can include, for example, a fill port housing, a sensor housing, and any other type of housing that can be used in an implantable restriction system and desired to have an adjustable height. The housing can lower in profile over time, e.g., as the patient loses weight, thereby maintaining the housing in a generally predictable location where it can be found and accessed.

A gastric reduction apparatus endoscopically draws stomach walls into apposition. The apparatus includes an applicator body having a proximal end and a distal end. The applicator body also includes a suction slot shaped and dimensioned for housing a corkscrew anchor. A firing mechanism is associated with the corkscrew anchor for rotation of the corkscrew anchor in a manner causing the corkscrew anchor to penetrate and engage tissue brought adjacent the suction slot. A method for gastric reduction is achieved by introducing a gastric reduction apparatus as disclosed above within the stomach of an individual, applying the corkscrew anchor to a stomach wall and drawing stomach walls together to create a cavity within the stomach.

A method for treating eating disorders comprising the steps of generating a neuro-electrical satiety signal that substantially corresponds to a neuro-electrical signal that is generated in a body and produces a satiety effect in the body, constricting the stoma of the stomach, and transmitting the neuro-electrical satiety signal to the subject.

Devices and methods of forming a compliant gastroplasty are presented. In general, fasteners that can reversibly couple are inserted into gastric tissue to form a gastric restriction. When an expanding pressure in the stomach exceeds a certain limit, the coupled fasteners can decouple to accommodate and relieve the excess pressure. Upon subsequent stomach shrinkage, fasteners are brought back into proximity and recouple to reform the gastroplasty. In particular, magnetic fasteners can be inserted into gastric tissue by injecting a solidifying composition into the tissue to form the fasteners. Various devices and methods for forming the gastroplasty are discussed.
