Embodiment Construction

[0031] In order to make the present invention more obvious and understandable, the preferred embodiments are described in detail as follows in conjunction with the accompanying drawings:

[0032] like Figure 1-5 As shown, the present invention provides a completely degradable left atrial appendage occluder; including a fixed plate 1 and a cover plate 3; one end of the occluder near the bottom of the left atrial appendage is provided with a fixed plate 1, and the other end is provided with a cover plate 3; A connecting rivet 6 is provided on the side of the cover plate 3 close to the opening of the left atrial appendage; the occluder is made of completely biodegradable materials. A waist 7 is provided between the fixed disk 1 and the cover disk 3, the fixed disk 1 is made as a cylinder shape, and the both sides of the fixed disk 1 are sunken inward to be set as a double-concave structure; For no waist 7 connection. The fixed disk 1 and the covering disk 3 are set to be woven...

Abstract

The invention relates to a completely degradable left atrial appendage occluder, and belongs to the technical field of medical instruments. The occluder comprises a fixed disc and a covering disc; a fixed disc is arranged at one end, close to the bottom of the left auricle, of the plugging device; a connecting rivet is arranged on one side, close to the left auricle opening, of the covering disc; and the plugging device is made of a completely biodegradable material. The left auricle plugging device provided by the invention becomes a bridge for endothelial cells to climb after being implanted into a body, and after the left auricle plugging device is implanted for a period of time, the surface of the left auricle plugging device is coated by new endothelial tissues, so that the self-plugging of the left auricle is realized. The plugging device is finally degraded by the body, so that the left auricle is completely filled with self tissues, and long-term complications and potential safety hazards caused by metal remaining in the body are avoided.

Description

technical field [0001] The invention relates to a completely degradable left atrial appendage occluder, which belongs to the technical field of medical instruments. Background technique [0002] The left atrial appendage is located on the inner corner of the left atrium, which is a dead end for blood, and the main relevant people with potential risks are patients with atrial fibrillation. After the atrial systolic pressure is lowered in patients with atrial fibrillation, the blood flow in the left atrial appendage will be slower, which will easily lead to blood coagulation into thrombus. If the thrombus falls off, it is likely to reach the intracranial blood vessels through the blood flow and block the tiny cerebral blood vessels, resulting in ischemic stroke. 17% of patients with atrial fibrillation develop blood clots, and about 91% of these blood clots originate from the left atrial appendage. Stroke caused by atrial fibrillation has three characteristics: high disabili...
