Abstract: Devices, systems, and methods can be used for the closure of surgical wounds. For example, surgical wounds can be closed using magnetic closure devices rather than the conventional methods of using sutures, clips, or staples. Additionally, in some implementations the magnetic closure devices provided herein are delivered laparoscopically or endoscopically via a vacuum catheter.

Abstract: Devices and methods can be used to deliver thermal therapy to treat tissue. For example, this document provides devices and methods for treating varices, varicosity, other bleeding vessels, polyps, and cancer using microwave-delivered thermal therapy in a minimally invasive fashion. In some embodiment's provided herein, a multidirectional thermal therapy that does not injure surface tissues but causes endothelial injury and coagulation is described. In some implementations, varices are suctioned into a cup that is configured to deliver thermal therapy to the varices, resulting in coagulation.

Abstract: Methods and apparatus for inducing weight loss using blood flow control are described herein. The apparatus and methods operate by controlling blood flow to the stomach and/or small bowel.

Abstract: Obesity treatment apparatus and methods are described herein involving gastric recycling of food are described herein. In one or more embodiments, the gastric recycling apparatus keeps returning chyme to the stomach increasing satiety signals and delaying hunger signals associated with an empty stomach. It may also may slow the emptying of the stomach as the caloric load in the stomach delays emptying and/or limit absorption of food within the small intestine by delivering at least a portion of food passing through the small intestine back into the stomach.

Abstract: This document provides methods and materials involved in disrupting electrical activity in the stomach. For example, methods and materials involved in delivering one or more electrical shocks to the stomach (e.g., the muscularis propria) in a manner that disrupts the normal electrical activity of the stomach (e.g., defibrillating the stomach) are provided.

Abstract: Methods and devices are disclosed for supporting and holding open a tubular structure in the body of an animal or human. In one form, the device is a manually adjustable variable outside diameter stent that can be repositioned or removed. The stent includes an elastic tubular body and an adjustment mechanism for the moving two ends of the body toward or away from each other. The elastic tubular body comprises a braiding of two groups of spaced apart helically wound elastic strands. The adjustment mechanism includes a bracket, a tension adjustor, and a tensioning wire attached to the bracket and the tension adjuster. The bracket and the tension adjuster are attached to one or more of the elastic strands of the two groups. Using the adjustment mechanism, the distance between the bracket and the tension adjustor can be decreased causing the outside diameter of the body to increase, or vice versa.
