If the foramen ovale is still not closed in children over 3 years old, it is called a patent foramen ovale. In adults, 20% to 25% of the foramen ovale is not completely closed. Patent foramen ovale is the most common congenital heart abnormality in adults. Many studies in recent years have shown that there is a close relationship between patent foramen ovale and patients with unexplained stroke. According to the etiological treatment, closing the open foramen ovale in high-risk groups is expected to reduce the incidence of patients. In addition, patent foramen ovale has also been found to be associated with the onset of decompression sickness, migraine, etc. Closure of foramen ovale may benefit the above patients.

本申请人发现现有技术至少存在以下技术问题:现有治疗上述疾病的方式是利用封堵手术,在体内放置一个较大的金属房间隔缺损封堵器。上述封堵器通常体积较大,且由于心脏内结构复杂,且将封堵器放置在心脏内,很多患者不易接受,近期及远期都可能会增加并发症的发生风险,难以做到反复释放回收。The applicant finds that the prior art has at least the following technical problems: the existing way of treating the above-mentioned diseases is to use closure surgery to place a large metal atrial septal defect occluder in the body. The above-mentioned occluders are usually large in size, and due to the complex structure of the heart, and the placement of the occluder in the heart, many patients are not easy to accept, and the risk of complications may increase in the short and long term, making it difficult to release repeatedly Recycle.
