Embodiment Construction

[0084] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to specific drawings.

[0085] refer to Figure 1 to Figure 4 , an extruded left atrial appendage occluder, including an occlusion balloon 100 and an end cap 200 .

[0086] refer to Figure 1 to Figure 16 , the blocking balloon 100 is used to block the opening of the left atrial appendage and the detachable connecting end cap 200 . The occlusion balloon 100 includes a balloon body 110 and a connector 120 .

[0087] The balloon body 110 is a hollow structure, and at least part of the diameter of the outer circumference of the balloon body 110 is larger than the diameter at the opening of the left atrial appendage, so as to block the opening of the left atrial appendage. like Image 6 As shown in , the proximal end of the balloon body 110 has an outer circumference whose...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an extrusion type left auricle plugging device and a using method thereof. The extrusion type left atrial appendage occluder comprises an occluding balloon and a left atrial appendage occluder body, the end cover is detachably connected with the blocking balloon; the plugging balloon comprises a balloon body which is of a hollow structure, and at least part of the diameter of the outer circumference of the balloon body is larger than the diameter of a left auricle opening so as to plug the left auricle opening; the connecting piece is connected with the balloon body, a conveyor connecting part is arranged at the near end of the connecting piece, an end cover connecting part is arranged at the far end of the connecting piece, and an end cover is detachably arranged on the side edge of the far end of the balloon body through the end cover connecting part; the end cover is telescopic and has an expansion state and a contraction state, and when the end cover is in the expansion state, the outer edge of the end cover inclines towards the balloon body side. The attaching area of the outer edge of the end cover obliquely arranged and the blocking balloon is larger, and attaching is more stable.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a left atrial appendage occluder. Background technique [0002] Atrial fibrillation (also known as atrial fibrillation) is the most common persistent cardiac arrhythmia with high mortality and disability rates. The main hazard of atrial fibrillation is that it is prone to thrombotic events. Thrombotic events are mainly caused by the thrombus falling off the heart wall and entering various parts of the body through the blood circulation, resulting in problems such as stroke and cerebral apoplexy. The left atrial appendage is the main site of thrombosis. . [0003] At present, in order to avoid thrombus in the left atrial appendage, left atrial appendage occlusion is generally performed, that is, the left atrial appendage is blocked by an occluder to isolate the left atrium and the left atrial appendage, so as to prevent the thrombus generated in the left atrial appendage ...
