An apparatus for treating obesity in a human or animal mammal patient. The apparatus comprising a first volume filling device segment and a second volume filling device segment. The first and second volume filling device segments are adapted to be assembled into an implantable volume filling device of a controlled size. Each one of the first and second volume filling device segment comprises at least one interconnecting structure. The interconnecting structure of the second volume filling device segment is adapted to be formed fitted, such that the first and second volume filling device segment can be assembled into the volume filling device. The assembled volume filling device is adapted to be at least substantially invaginated by a stomach wall portion of a patient, with the outer surface of the device resting against the stomach wall, such that the volume of the food cavity is reduced in size.

A surgical stapling system for stapling the tissue of a patient is disclosed. The stapling system comprises a housing, a shaft extending from the housing, and an end effector extending from the shaft. The end effector comprises a plurality of staples removably stored therein and, also, an anvil configured to deform the staples. The stapling system further comprises a firing mechanism configured to deploy the staples along a staple firing path longer than 60 mm, a camera configured to capture an image of the patient tissue, a display, and a controller configured to generate an image of the staple firing path, wherein the images are displayed on the display.

The present disclosure relates generally to stents and methods for managing passage of material through a body lumen. In some embodiments, a medical stent may include a stent body defined by a hollow tubular elongate structure extending along a central axis, the stent body including a first portion and a second portion. The medical stent may further include a control region between the first and second portions, wherein in a first configuration the hollow tubular elongate structure of the control region is in a closed, twisted configuration, and wherein in a second configuration the hollow tubular elongate structure of the control region is in an open, expanded configuration.

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 contractile element further includes a closure for forming the contractile element into a closed loop around said hollow body organ, the closure having a plurality of lips arranged to engage the contractile element.

An apparatus for the treatment of acid reflux disease comprising two or more movement restriction device segments adapted to be assembled movement restriction device of a controlled size. The assembled movement restriction device can at least partly be invaginated by a patient's stomach fundus wall. A substantial part of the outer surface of the movement restriction device is adapted to rest against the stomach wall without injuring the latter in a position between the patient's diaphragm and at least a portion of the lower part of the invaginated stomach fundus wall, such that movement of the cardiac notch of the patient's stomach towards the patient's diaphragm is restricted, to thereby prevent the cardia from sliding through the patient's diaphragm opening into the patient's thorax, so as to maintain the supporting pressure against the patient's cardia sphincter muscle exerted from the patient's abdomen.

An esophageal device is used to recognize, diagnose, characterize, or relieve an impact of an abnormal or defective UES anatomy, physiology, or functionality. In one implementation, the esophageal device measures a UES response to esophageal fluid infusion to detect or characterize an abnormality or defective UES anatomy, physiology, or functionality. An Upper Esophageal Sphincter compression device is used to increase intra-luminal pressure within the Upper Esophageal Sphincter of a patient in order relieve an impact of an abnormal or defective UES anatomy, physiology, or functionality.

A gastroesophageal reflux preventer and related methods are provided. A gastroesophageal reflux preventer is configured to be positioned around the exterior of a body organ and may include an elongate portion including a plurality of nodes positioned along at least a portion of the length of the elongate portion.

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.

A medical device may include an implantable device for treating a body tissue structure. The implantable device may include a plurality of bodies spaced from adjacent bodies and arranged so as to be configured to extend around an exterior surface of a body tissue structure. The bodies may be configured to apply a static force to the body tissue in a relaxed state and may adjust or move in response to a radially outward force above a threshold level that is acting on one or more of the bodies. The bodies may be pliable and/or made with a pliable material. The bodies may be interconnected via interconnecting regions. One or more of the bodies may be configured to articulate so as to conform to movement of a body tissue structure. A skeletal component may or may not extend through one or more of the plurality of bodies.

A tissue displacing and fastening device is provided for manipulating and fastening tissue together. The device includes a tissue displacing elements, which displaces tissue. A fold is formed from the displaced tissue and the tissue is fastened together to secure the fold.
