PROBLEM TO BE SOLVED: To provide medical devices.SOLUTION: A medical device comprises: a flexible hollow tube 20 extending from a proximal end to a distal end and defining a channel 26 therebetween, a series of openings 28 being defined in a distal portion 22 of the tube 20 allowing fixation of tissue using suction; and a flexible member 40 having an initial position disposed alongside the tube 20 and being deployable to a subsequent position in which the flexible member 40 engages the greater curvature of the stomach. The application of suction places the tube along the lesser curvature of the stomach, fixes anterior and posterior walls of the stomach, and prevents their movement. The tube is visible under stomach tissue. The flexible member 40 is configured to be deployable to automatically assume a shape of the greater curvature of the stomach. The flexible member includes a bulging region and a tapering region when deployed. The flexible member includes at least one illumination device. |
