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, at present I
State there are about 8,000,000 patients with atrial fibrillation, and quantity increases year by year, and patients with atrial fibrillation has 0.4%-1% every year
People there is apoplexy, say, that in 8,000,000 patient groups, have 3.2-8's ten thousand every year
People is 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, the most every 6 example patients with cerebral apoplexy have
1 is patients with atrial fibrillation.Non-valvular heart disease patient's incidence of stroke is the 5.6 of normal person
Times, valvular heart disease atrial fibrillation incidence of stroke is 17.6 times of normal person；And what atrial fibrillation caused
Apoplexy consequence is even more serious, and mortality rate and disability rate reach 70%.Disease to valvular atrial fibrillation
People, the atrium thrombosis of 57% derives from left auricle, for the patient of non-valve atrial fibrillation, 90%
Left Atrial derives from left auricle.Even if recovering Dou Lvhou, left auricle shrinks to time and presses down, and still has
Thrombosis may be formed again.
The method of prevention atrial fibrillation cerebral infarction mainly has three kinds the most clinically.The first side
Method is to take anticoagulant, and such as warfarin, but application warfarin has certain bleeding risk,
And need frequently monitor, contraindication is the most, and clinical practice is the most difficult；Additionally warfarin is also
There is the possibility causing osteoporosis and soft tissue necrosis.Second method is that cardiac operation is same
Auricle is directly excised or ligatured to phase, and the main deficiency of this method is the of completely closed rate of left auricle
Relatively low, previously the success rate a maximum of about of 80% of left auricle is excised in research display completely；And have
Tear, hemorrhage risk.The third method is to close left auricle by apparatus, and percutaneous gets involved a left side
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 the left atrium entrance of left auricle, blocks left auricle and left atrium blood flow,
The thrombosis preventing left auricle from producing enters into atrium, reduces the risk that apoplexy occurs.Through one section
After time, stopper surface endothelialization, can thoroughly solve Left atrial appendage and enter left atrium
Problem.
Left auricle transcatheter is the focus of research both at home and abroad at present, and market also has external envelope
Stifled apparatus, and domestic related equipment is also among research and development.Due to coming in every shape of left auricle,
And irregular, the coupling of stopper and auricle has certain 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, and only stopper is complete
After full release, just it is capable of determining whether to be discharged into position, if position is improper, after can only regaining completely,
Again discharging, the release process before repetition, the accuracy of location is poor.
(2) atrial appendage occlusion device is most with barb structure, possible repeatedly release, meeting at present
Make auricle easily occur piercing through, the adverse events such as tear, patient is damaged.
