Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of atrial appendage occlusion device.
Background technology
Atrial fibrillation is one of the most most commonly seen arrhythmia, and number of patients is numerous, and current China there are about 8,000,000 atrial fibrillations
Patient, and quantity increases year by year, patients with atrial fibrillation has the people of 0.4%-1% that apoplexy occurs every year, say, that ill 8,000,000
In crowd, there is the people of 3.2-8 ten thousand every year probably due to atrial fibrillation produces cerebral infarction.Apoplexy is the harm that atrial fibrillation is maximum,
Research find 15～20% cerebral infarction caused by atrial fibrillation, having 1 in the most every 6 example patients with cerebral apoplexy is patients with atrial fibrillation.
Non-valvular heart disease patient's incidence of stroke is 5.6 times of normal person, and valvular heart disease atrial fibrillation incidence of stroke is normal person
17.6 times；And apoplexy consequence that atrial fibrillation causes is even more serious, mortality rate and disability rate reach 70%.To valvular atrial fibrillation
Patient, the atrium thrombosis of 57% derives from left auricle, and for the patient of non-valve atrial fibrillation, the Left Atrial of 90% derives from
Left auricle.Even if recovering Dou Lvhou, left auricle shrinks to time and presses down, it is possible to form thrombosis again.
The method of prevention atrial fibrillation cerebral infarction mainly has three kinds the most clinically.First method is to take anticoagulation
Thing, such as warfarin, but application warfarin has certain bleeding risk, and need frequently monitor, and contraindication is the most, clinical should
By more difficulty；Additionally warfarin also causes the possibility of osteoporosis and soft tissue necrosis.Second method is department of cardiac surgery
Auricle is directly excised or ligatured to the same period in operation, and the main deficiency of this method is that the of completely closed rate of left auricle is relatively low, previously grinds
Study carefully display and excise the success rate a maximum of about of 80% of left auricle completely；And have tear, hemorrhage risk.The third method is logical
Crossing apparatus Guan Bi left auricle, percutaneous gets involved left atrial appendage occlusion product, such as PLAATO, WATCHMAN, ACP etc..Sealed by left auricle
Stifled device blocks left auricle, can reduce the incidence rate of atrial fibrillation patient's apoplexy.Its action principle is: occluder for left auricle closes a left side
The left atrium entrance of auricle, blocks left auricle and left atrium blood flow, and the thrombosis preventing left auricle from producing enters into atrium, reduces
The risk that apoplexy occurs.Through after a period of time, stopper surface endothelialization, can thoroughly solve Left atrial appendage and enter the left heart
The problem in room.
Left auricle transcatheter is the focus of research both at home and abroad at present, and market also has external closure apparatus, and domestic
Related equipment also research and development among.Due to coming in every shape of left auricle, and irregularly, the coupling of stopper and auricle has one
Fixed difficulty；And current atrial appendage occlusion device has a disadvantage in that
(1) existing atrial appendage occlusion device is all a step release, can not be presetting, after only stopper discharges completely, just can determine that
Whether release puts in place, if position is improper, after can only regaining completely, again discharges, the release process before repetition, the standard of location
Exactness is poor.
(2) atrial appendage occlusion device is most with barb structure, possible repeatedly release at present, and auricle can be made thorn easily occur
Wear, the adverse events such as tear, patient is damaged.
