Embodiment 1

[0048] This embodiment provides a device suitable for patients with patent foramen ovale.

[0049] refer to Image 6 , the device includes an atrial septum fixing clip and a braided mesh for covering, wherein the atrial septum fixing clip forms a clamp, and the braided mesh forms an extension.

[0050] Wherein, the interatrial septum fixing clip consists of two V-shaped titanium clips, an inner connecting rod and an outer connecting rod. The V-shaped titanium clamp is made of pure titanium wire or titanium alloy wire, including a clamping section with a V-shaped bending part and two clamping sections integrally formed with the clamping section, and a V-shaped clamping section is opened on the clamping section. Shaped groove. At the same time, the clamping section of the V-shaped titanium clip makes the two clamping sections relatively close to each other in a natural state, so as to clamp the object or human tissue between the two clamping sections. The two ends of the inne...

Embodiment 2

[0064] The device provided in this embodiment can adapt to the disease of patent foramen ovale, and can also adapt to the disease of defect of foramen primum.

[0065] From the perspective of embryology and pathogenesis, the primary hole defect refers to the fact that the developing primary atrial septum stops growing and does not fully fuse with the endocardial cushion, thus forming a gap between the primary atrial septum and the endocardial cushion. Clearance.

[0066] For this, Figure 10 It is shown that the device in this embodiment has a primary ablation hole on the braided mesh of the first embodiment, and the primary ablation hole is equipped with a primary blocking umbrella capable of sealing the primary gap of the primary opening defect.

[0067] In this embodiment, when the primary hairline gap is just opposite to the primary hairline gap, the primary hairline plugging umbrella can block the gap of the primary hairline defect on the one hand, and pass through the p...

Embodiment 3

[0070] The device provided in this embodiment can adapt to the disease of patent foramen ovale, and can also adapt to the disease of defect of foramen primum and foramen secondary.

[0071] refer to Figure 11 , the device in this embodiment includes a secondary occlusion umbrella, a primary occlusion umbrella and a braided mesh for covering.

[0072] Among them, the woven mesh covers the foramen ovale, and the upper end is attached to the secondary atrial septum, and the lower end is attached to the primary atrial septum. The woven mesh is provided with a primary hair give way hole at the gap position where the primary hair hole is defective. The primary occlusion hole is closed with the primary occlusion umbrella, and the primary occlusion umbrella compresses the braided mesh on the primary atrial septum. The braided mesh has a secondary abdication hole at the gap between the left atrium and the right atrium that may exist on the secondary atrial septum. The secondary rel...

Abstract

A device suitable for a patent foramen ovale patient comprises a connecting part and an extending part. The upper part of the connecting part is connected with a secondary atrial septum; the upper section of the extension part is connected with the lower portion of the connecting part, the middle section of the extension part extends in the original growth direction of the secondary atrial septum to at least cover the foramen ovale, and the lower section of the extension part is attached to the side, facing the right atrium, of the primary atrial septum. According to the device suitable for the patent foramen ovale patient, the secondary atrial septum is lengthened, so that the foramen ovale is difficult to open, and meanwhile, the possibility that most of the secondary atrial septum continues to grow and is fused with the primary atrial septum is reserved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device adapted to patients with patent foramen ovale. Background technique [0002] Patent foramen ovale is a common congenital heart disease at present. In 20% to 25% of healthy people, the foramen ovale valve and atrial septum do not fully fuse, that is, patent foramen ovale. [0003] Please refer to figure 1 When the healthy embryo grows to the end of the 4th week, the primitive heart chamber will be divided into four atrioventricular chambers. The specific separation process is that the middle parts of the ventral and dorsal sides of the primitive heart chamber of the embryo grow oppositely to form a prominent thickening part. These two thickened parts are the ventral and dorsal endocardial cushions, respectively. [0004] After that, the two endocardial cushions on the ventral and dorsal sides will gradually approach and fuse with each other near the midline, and the tissu...
