Devices and methods for treating obesity are provided. More particularly, intragastric devices and methods of tracking and locating the same are provided.

An intragastric weight-loss device is disclosed. The device includes a proximal occlusion member comprising a spiral structure, a bridging member, and a distal occlusion member. The spiral structure can be configured to spiral into a bulbous shape when the proximal occlusion member is delivered into the stomach. The bridging member can extend from the proximal occlusion member. The distal occlusion member can be coupled to a distal end of the bridging member. The proximal occlusion member can be configured to intermittently obstruct a pyloric valve of a patient such that passage of food through the pyloric valve is slowed.

A medical device for narrowing or closing an anatomical channel includes a band part (1) which can be placed around the body tissue (2) surrounding the anatomical channel and which can be closed to form a ring that encloses a through-opening (6) for the body tissue, wherein the band part (1) has a hollow chamber (3), and wherein the through-opening (6) can be made smaller by introducing a fluid into the hollow chamber (3). The medical device moreover includes a pump unit (10) which serves to convey the fluid and which has an electric drive (15) controllable by an electronic control system of the device, wherein a pressure value corresponding to the pressure of the fluid in the hollow chamber (3) or dependent on this pressure can be detected by the electronic control system. The device moreover has an air pressure sensor (23) for detecting the atmospheric pressure.

Tissue expanders and methods of their manufacture and use are disclosed herein. A tissue expander shell according to the present disclosure may include a shape and topography that facilitates uniform or substantially uniform expansion and contraction of the tissue expander. In at least one example, the shell may include a series of topographical features, such as ridges, grooves, channels, valleys, canals, protrusions, pleats, creases, or folds. In some embodiments, these features may have a curved or wavy cross sectional profile. For example, the shell may include a series of concentric curved ridges.

A bariatric clamp may include substrate members overmolded in polymer forming first and second elongated portions, a bight portion having a flexible hinge, one or more inflatable portions disposed at least partially along interior sections of the first and second elongated portions; and a port coupled to at least one of the inflatable portions and configured to adjust inflation of the inflatable portions. The inflatable portions are provided to assist in retaining the clamp in a closed position to partition the stomach and to adjust a pressure of the clamp when partitioning the stomach.

Devices and methods for treating obesity are provided. More particularly, intragastric devices and methods of fabricating, deploying, inflating, monitoring, and retrieving the same are provided.

A system includes an adjustable implant configured for implantation internally within a subject and includes a permanent magnet configured for rotation about an axis of rotation, the permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant. The system includes an external adjustment device configured for placement on or adjacent to the skin of the subject having at least one magnet configured for rotation, the external adjustment device further comprising a motor configured to rotate the at least one magnet and an encoder. Rotation of the at least one magnet of the external adjustment device effectuates rotational movement of the permanent magnet of the adjustable implant and alters the dimension of the adjustable implant. Drive control circuitry is configured to receive an input signal from the encoder.

One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. Occlusion devices can be integrated with a catheter or tube to occlude one or more proximal or distal landmarks of a stomach and a stapling guide may be used to occlude a lateral boundary of the stomach to define a cavity. A volume of the potential resultant sleeve may be determined by inserting fluid or gas into the catheter or tube, measuring pressure, and calculating the volume of the cavity.

An implantable device having an expandable element, such as a balloon, exerting a radially-outwardly directed anti-migration force to hold the implantable device in place. The implantable device occlusion device may be an occlusion device configured to be inserted through a body passage. The implantable device may include a first component and a second component expandable within a lumen of the first component to exert an antimigration force against the first component. The first component may be an expandable stent coated to resist tissue ingrowth, and the second component may be an expandable balloon configured to exert an anti-migration force against the expandable stent.
