20220168126 · 2022-06-02 ·

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.

20220160622 · 2022-05-26 ·

The present invention provides combination therapies for treating a metabolic disorder, such as type 2 diabetes, obesity, and related comorbidities (e.g., NASH or NAFLD)) in an individual undergoing treatment with a gastrointestinal implant. The combination therapies described herein include methods for treating an individual with a gastrointestinal implant with a metabolic agent, a bariatric procedure, and/or a microbiota modulator.

SURGICAL DEVICE FOR CONTROLLED ANCHORING IN THE INTESTINE
20230270440 · 2023-08-31 ·

A surgical anchor device for being anchored on the mucous membrane of the inner wall of the intestine, the device having a temporary anchor element presenting anchoring that can be modified in a controlled manner and having a first substantially cylindrical multiply-perforated wall presenting properties of radial elasticity whereby the first wall presents an outer diameter that can be varied in controlled manner, wherein a portion of the inner surface of the first wall is lined with an independent leakproof inner sheath having only its longitudinal ends fastened to the anchor element to define a suction chamber between the inner sheath and the first wall, the temporary anchor element being coupled to a flexible or semi-rigid tube extending outside the anchor element, an open end of the injection-suction tube opening out into the suction chamber enabling air to be injected into or sucked out from the suction chamber.

Conforming anchor for duodenal barrier

An apparatus comprises a sleeve, a seal, and an anchor assembly. The sleeve is flexible and non-permeable and is configured to fit in a duodenum. The seal is positioned at the proximal end of the sleeve and is configured to seal the proximal end of the sleeve against the stomach mucosa, the pylorus, or the duodenum mucosa. The anchor assembly comprises a pair of atraumatic anchor ends and a resilient member positioned between the anchor ends. At least a portion of the resilient member extends along at least a portion of the length of the sleeve. The resilient member is configured to bias the anchor ends generally toward each other, to thereby substantially anchor the sleeve in the duodenum. The sleeve is configured to prevent chyme from contacting the mucosa of the duodenum; and to prevent enzymes excreted in the duodenum from mixing with chyme in the duodenum.

Endoluminal anastomosis and tissue closure devices

Multiple endoscopic devices and methods for closing perforations and/or creating anastomoses in tissue are described. For example, this document provides devices and methods for performing esophagogastric anastomoses and for closing esophageal perforations in a minimally invasive fashion. The devices and methods provided herein can also be used for, without limitation, colorectal anastomoses, any bowel anastomosis, gastric bypass anastomoses, and broader vessel anastomoses.

Systems and methods for anchoring and restraining gastrointestinal prostheses

Systems and methods for anchoring and restraining gastrointestinal prostheses are disclosed. In various examples, the systems and methods include securing a gastrointestinal device within a patient's anatomy by extending an anti-migration anchor through a plurality of portions of the gastrointestinal device to couple together the plurality of portions of the gastrointestinal device. In some examples, the anti-migration anchor extends through tissue situated between the plurality of portions of the gastrointestinal device.

SURGICAL DEVICES AND METHODS FOR BARIATRIC AND GASTROESOPHAGEAL SURGERY
20220151724 · 2022-05-19 · ·

Disclosed are various embodiments for improved surgical devices and methods of using the same in connection with bariatric and gastroesophageal surgery. The present disclosure includes a lighted bougie device that can include an elongate member and a light source. The light source can be configured to emit near-infrared light. The light source can also be positioned about the bougie such that light emitted from the light source illuminates along a portion of the bougie.

Systems and methods for measuring volume of potential sleeve in a sleeve gastrectomy

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.

Gastrointestinal implant delivery systems and methods

The present invention provides delivery systems for positioning a gastrointestinal implant in a patient, for example, for treatment of a metabolic disease. Also provided are methods for assembling the delivery systems, methods of positioning a gastrointestinal implant, and methods of treatment of metabolic diseases, such as type 2 diabetes, non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD), obesity, and related comorbidities thereof.

DEVICES, SYSTEMS, AND METHODS RESISTING MIGRATION AND METHOD OF IMPLANTATION THEREOF

An implantable device configured to be deployed at a deployment site such as across a body passage. The implantable device has features enhancing the resistance of at least a portion of the implantable device to migration from the deployment site. The implantable device may have surfaces contacting tissue at the deployment site which are configured to promote tissue ingrowth with respect to the implantable device. Surfaces of the implantable device not contacting tissue may be enlarged and coated with a coating material increasing the strength of the coated portions of the implantable device to resist migration of the implantable device with respect to the deployment site.
