An intraluminal device and method of deploying an intraluminal device in a portion of a lumen includes the device having a body with a wall defining a surface. The surface is configured to a portion of a lumen. An anchor system made up of a plurality of anchors fixes the body to an inner wall of the lumen. At least intermittent pressure with the surface to the inner wall of the lumen. A tissue fold of the inner wall of the lumen is formed. Thee tissue fold is adjacent the body wall and transmits a force between the inner wall of the lumen and the device body.

Single member intraluminal device and method of fixation

An intraluminal device and method of resisting migration of a device in a lumen, the lumen having muscle defining an intraluminal sphincter includes a device having a body with a size and shape of a portion of the lumen. The device further includes at least one tine extending distally from the body. The at least one tine is rigid or semi rigid. The device is deployed in the lumen with the body proximal the sphincter with respect to peristaltic movement of the lumen and with the at least one tine penetrating the muscle of the sphincter to resist distal migration.

Intraluminal device and method with anti-migration

A bariatric device and method of causing at least partial satiety in a recipient includes positioning a body in a recipient, the body having a wall defining a lumen, the wall configured to generally conform to the shape and size of the proximal cardiac portion of the stomach. Force is exerted with the wall on the proximal cardiac portion of the stomach in the absence of food thereby activating receptors located in the proximal cardiac portion of the stomach, thereby influencing a neurohormonal feedback mechanism of the recipient to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food.

Bariatric device and method

A bariatric device includes an esophageal member having an esophageal surface that is configured to generally conform to the shape and size of a portion of the esophagus and an anchoring technique anchoring the esophageal member to the portion of the esophagus. The bariatric device includes a cardiac member having a cardiac surface that is configured to generally conform to the shape and size of a portion of the cardiac portion of the stomach and a connector connected with the esophageal member and the cardiac member to cause strain to be applied by the cardiac member to the cardiac portion of the stomach. The strain applied by the cardiac member to the cardiac portion of the stomach causes satiety in the absence of food. The connector is adapted to pass through the gastroesophageal junction while leaving a continuous portion of the gastroesophageal junction substantially unrestrained.

An intraluminal device and method of fixation of an intraluminal device at a recipient having an esophagus, a stomach with a cardiac portion and a GE junction between the esophagus and the cardiac portion of the stomach includes deploying the intraluminal device to the recipient. The intraluminal device has a wall defining a cardiac member that is configured to the size and shape of the cardiac portion of the stomach and deployed to the cardiac portion of the stomach and an esophageal member that is configured to the size and shape of a portion of the esophagus and deployed to the esophagus. The intraluminal device having a connector connected with the esophageal portion and cardiac portion and deployed to the GE junction. The wall is fixed to the recipient to resist distal migration of the wall. The fixing includes the wall having a wall characteristic that is configured to facilitate tissue ingrowth. The wall is temporarily fixed to the recipient to resist distal migration of the wall while tissue ingrowth occurs at the wall characteristic.

Intraluminal device and method of fixation

An intraluminal device adapted to be positioned in a lumen that experiences peristalsis and method of fixation of an intraluminal device in the lumen, includes a wall configured to the size and shape of a portion of the lumen and at least one core. The at least one core is removably connected with a portion of the device wall. The at least one core is configured to be positioned against the lumen when the wall is positioned in the lumen. In this manner tissue envelopes the core during implantation of the intraluminal device. The at least one core is configured to be axially removable in situ from the tissue enveloping the core after the device has been deployed by disconnecting the core from the portion of the wall in order to explant the intraluminal device from lumen.

Fixation of intraluminal device

An intraluminal device and method of fixation of an intraluminal device in a mammalian lumen or hollow organ that experiences peristalsis includes a fixation system that is adapted to resist distal migration of the intraluminal device in the lumen or hollow organ. The intraluminal device has a wall surface configured to the size and shape of a mammalian lumen or hollow organ. A fixation system is adapted to resist distal migration of the body in the lumen or hollow organ. The fixation system includes a bio-absorbable material around at least one of the elongated members.

A medical device adapted to be fixed in a hollow organ or cavity lined with mucosa includes a wall having an outer surface with a size and shape that is configured to a portion of a cavity or hollow organ lined with mucosa and a fixation mechanism. The fixation mechanism is adapted to fix the wall with the portion of the cavity or hollow organ. The fixation mechanism has at least two adjacent openings in the wall between proximal and distal ends of the wall. The openings being large enough to receive a section of the mucosa extending in the openings when said wall is positioned in the hollow organ or cavity. The openings are separated by a bridge and are close enough together that the mucosa that extends into the openings comes together over the bridge to fix the medical device in the hollow organ or cavity.

Mucosal capture fixation of medical device

An intraluminal device and method of fixation of an intraluminal device to resist distal migration in a mammalian lumen or hollow organ that is subject to peristalsis, according to an aspect of the invention, includes spaced apart wall portions connected with a connector. The wall portions are configured to the size and shape of a portion of the lumen or hollow organ and the connector is configured to be positioned against a wall of the lumen or hollow organ. The intraluminal device is positioned in a mammalian lumen or hollow organ that is subject to peristalsis. The device is fixed in the lumen or hollow organ against distal migration, wherein tissue lining the lumen or hollow organ bridges over the connector. The device is explanted after tissue bridges over the connector including separating the connector from one or both of the wall portions and withdrawing the connector axially from the tissue bridging over the connector.
