Upper stomach gastric implants

A variety of passive intragastric implant devices for obesity treatment are disclosed. Such passive devices may not autonomously change shape, but instead react within the stomach to induce satiety. The devices may provide slowed entry into the stomach, thus reducing the intake capacity. Additionally, the devices may contact areas within the stomach, such as the cardia surrounding the esophageal sphincter, to stimulate satiety-inducing nerves. Some devices combine two or more of these satiety-inducing features. Methods of implant are disclosed including compressing the devices within a delivery tube and transorally advancing the devices through the esophagus to be deployed within the stomach. Removal of the devices occurs in the reverse. The implants are formed of materials that permit the implant to be compressed into a substantially linear transoral delivery configuration and that will resist degradation over a period of at least six months within the stomach.

Cam-shaped clamping surfaces prevent slippage of the stomach tissue from within the clips. Methods of implant are disclosed including delivering the device through a transoral delivery tube and advancing the device through the esophagus to be deployed within the stomach. Removal of the device occurs in the reverse.

Intragastric implants with collapsible frames

Transoral obesity treatment devices and related methods for operation thereof are described which occupy space within a stomach and/or stimulate the stomach wall.

The life span of these devices may be material-dependent upon long-term survivability within an acidic stomach, but is intended to last one year or longer. The devices have the capacity to vary in size and are desirably self-actuating in that they change shape and/or volume using internal motors or actuators. The changing character of the devices helps prevent the person's stomach from compensating for the implant, such as sometimes happens with static intragastric devices.

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.

Fatigue-resistant gastric banding device

A fatigue-resistant inflatable gastric banding device suitable for laparoscopic placement around the stomach of a patient for the treatment of obesity and a method for such treatment are disclosed. The device includes a gastric band having a chambered inflatable member, substantially coextensive with an inner stomach facing surface of the band, that does not crease, wrinkle or fold when adjusted, so as to present a substantially smooth contour along the inner circumference, and to avoid fatigue or failure of the member itself. A gastric band having multiple inflatable compartments or chambers, which may be inflated together or individually is also disclosed.

Self-adjusting gastric band

A self-adjusting gastric band comprises an inflatable portion that includes a fluid such as saline. A reservoir is spaced from the inflatable portion according to a distance related to a wavelength of a peristaltic wave that propagates through the esophageal-gastric junction. A pressure-relief valve is coupled between the inflatable portion and the reservoir and allows an amount of the fluid to pass from the inflatable portion to the reservoir when a first force generates an increased pressure in the inflatable portion. The amount of fluid is released to allow the large bolus to pass through the esophageal-gastric junction. A contracted portion of the peristaltic wave is proximate the reservoir when an expanded portion of the wave is proximate the inflatable portion of the self-adjusting gastric band, to facilitate allowing the amount of the fluid to enter the reservoir.
