Cuff device for isolating main artery inner wall aneurysm cavity and using method thereof

Abstract

The invention, which belongs to the field of medical equipment, especially relates to a cuff device for isolating a main artery inner wall aneurysm cavity and a using method thereof. The cuff device comprises a foldable tubular cuff, a cuff release controller and a monitoring device. A connecting pipe is communicated to the tail end of the foldable tubular cuff. The cuff release controller includes a cuff accommodating cavity and a cuff releaser. The foldable tubular cuff is arranged into the cuff accommodating cavity after being folded and deformed along the long axis of the tubular structure; and the cuff releaser releases the foldable tubular cuff out of the cuff accommodating cavity. The monitoring device includes a cuff pressure monitoring device, a main artery blood pressure monitoring device and a cuff pressure manager. After the cuff device is implanted, fluid is injected through the cuff release controller to enable the cuff device to be expanded into a tubular structure, so that a tumor cavity is isolated; the fluid is extracted through the cuff releaser to enable the cuff device to shrink, so that the cuff device is taken out. Therefore, problems that the existing metalcovered stent cannot be taken out after being implanted and the price of the metal covered stent is high are solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cuff device for isolating an aneurysm cavity on the inner wall of a large artery and a method for using it. Background technique [0002] Aortic aneurysm refers to localized or diffuse dilation of the aortic wall. The main hazards are as follows: 1. Aneurysm rupture, the aneurysm wall gradually expands and becomes thinner due to the continuous impact of blood flow, and finally the tumor ruptures, causing fatal hemorrhage; 2. Adhesive thrombus forms, and the aneurysm expands If the inner surface of the tumor wall is rough, it is easy to form a thrombus, which can cause embolism if the thrombus falls off; 3. The tumor body oppresses the surrounding normal tissues and organs, causing discomfort or other diseases, such as oppressing the esophagus, causing dysphagia, and oppressing the trachea. Difficulty breathing, oppression of the recurrent laryngeal nerve causing hoarseness, etc....
