Title: BALLOON LEFT AURICLE OCCLUSION DEVICE
Abstract:
A balloon left auricle occlusion device, comprising a delivery means and an occluder. The delivery means first delivers the occluder to the interior of the left auricle, and then injects a solution into the occluder by means of a tube. The occluder comprises: a stent (2), a check valve (5), a multi-section positioning membrane (1), an infusion tube (4), and a barb (3); the multi-section positioning membrane (1) is connected to the stent (2) and comprises a head end positioning membrane (11), a middle positioning membrane (12), and a tail end positioning membrane (13); the stent (2) comprises a stent front end (22) and a stent rear end (23); the check valve (5) is provided within the stent rear end (23); the infusion tube (4) is connected to the stent rear end (23). The solution enters the multi-section positioning membrane and fills the multi-section positioning membrane in sequence, so as to form multiple balloon means. The balloon means on the occluder are closely attached to the inner wall of the left auricle and can be applied to different left auricle anatomic forms, thereby effectively preventing the occluder from falling off during an operation or after the operation, preventing blood clots from being omitted, and reducing complexity of occluder models and production costs.
