Abstract:
A method of performing bariatric surgery includes inserting a gastrectomy device into a stomach of a patient, positioning the gastrectomy device in a selected location in the stomach, transecting a portion of the stomach thereby reducing a size of the stomach, and applying a reinforcement scaffold to an outer surface of the stomach. The reinforcement scaffold is configured to maintain the reduced size of the stomach.
Abstract:
One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. The one or more medical devices may include a laparoscopic sleeve gastrectomy stapling guide in conjunction with a calibration tube in accordance with one or more examples. According to an example, the calibration tube may be a flared, multi- diameter calibration tube. The flared, multi-diameter calibration tube may have a first diameter along a portion of the tube and a second diameter that may larger than the first diameter along at least another portion of the tube. The calibration tube may be used in conjunction with the stapling guide to align stomach such that it may be stapled along the stapling guide (e.g., to perform the vertical sleeve gastrectomy).
Abstract:
A method of promoting tissue adhesion to reinforce tissue apposition that may include collecting a first tissue portion, placing a first tissue apposition means through the first tissue portion, collecting a second tissue portion, placing a second tissue apposition means through the second tissue portion, tightening the first and second tissue apposition means to approximate the first and second tissue portions, and placing a fixation agent between the first and second tissue portions. In this illustrative embodiment, the method promotes tissue adhesion between one or more portions of tissue, wherein the tissue adhesion may reinforce a tissue apposition.
Abstract:
An adjustable band or clamp or non-adjustable clamp is placed about the greater curvature of the stomach in a vertical orientation. The band or clamp completely compartmentalizes the stomach between a small vertical pouch and the fundus and body of the stomach. The fundus and body of the stomach are excluded from nutrients and are separated from a long narrow channel where the food travels. A small passage at the level of the antrum allows gastric juices to empty from the fundus and body of the stomach. The clamp may be applied during open surgery in laproscopic surgery or using a single port technique, or through any natural orifice in NOTES (Natural Orifice Transluminal Endoscopic surgery) or using a hybrid surgical technique.
Abstract:
A method for endoscopically preventing insufflation of the small bowel during gastric procedures includes applying an obstruction member at the pyloric sphincter to block the passage of gas from the gastric cavity into the small bowel and insufflating the gastric cavity.
Abstract:
A suture anchoring device includes a fastener body composed of a tube and a spool is mounted within the tube for rotation relative to the tube. Suture material is wrapped about the spool such that pulling of the suture material causes rotation of the spool within the tube. A one-way locking mechanism allows the spool to rotate freely in a first direction and prevents rotation in an opposite direction. A method for creating a tissue fold includes deploying a first suture anchoring device within the tissue with suture material extending proximally from the first suture anchoring device, deploying a second suture anchoring device within the tissue with a distal portion of the suture material extending between the first suture anchoring device and a proximal portion of the suture material extending proximally from the second suture anchoring device, and applying tension to the suture material to draw portions of the tissue together to form a tissue fold.
Abstract:
An apparatus for the treatment of acid reflux disease has an implantable movement restriction device adapted to be at least partly 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. The movement restriction device has a size of at least 125 mm 3 and a circumference of at least 15 mm.
Abstract:
Tissue manipulation and securement systems are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member and has a lower jaw member and an upper jaw member pivotably coupled to the lower jaw member. A reconfigurable launch tube is also pivotably coupled to the upper jaw member and is used to urge the jaw members from a low-profile configuration to an open configuration for receiving tissue. The tissue manipulation assembly may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. A second tool can be used in combination with the tissue manipulation assembly to engage tissue and manipulate the tissue in conjunction with the tissue manipulation assembly.
Abstract:
Disclosed is a system for endoscopically implanting a medical implant within a body cavity such as a human stomach. The system includes one or more anchors positionable within one or more openings formed in tissue within the body cavity, such as cutouts formed in plicated body tissue. Tools are disclosed for positioning the anchors within the openings, and for coupling the implant to the anchors.
Abstract:
A device, system and method for providing tissue and organ restriction. Embodiments of an implantable magnetic device arc described with respect to restricting gastric capacity while avoiding nutritional deficiencies and other complications. Further, a delivery device is described for facilitating the delivery of the magnetic device to a targeted site. Additionally, methods are described for delivering the magnetic devices to a stomach.
