Oval foramen unclosed plugging device, oval foramen unclosed plugging system and oval foramen unclosed plugging method

Abstract

The invention discloses an oval foramen unclosed plugging device, an oval foramen unclosed plugging system and an oval foramen unclosed plugging method. According to the invention, through connectionof a first connecting part with a second connecting part, a first plugging disc and a second plugging disc are mounted on a conveying piece, so the first plugging disc and the second plugging disc canbe smoothly placed in the right atrium and the left atrium; and through extrusion of the first plugging disc and the second plugging disc, a first connecting piece is connected with a second connecting piece, so the first plugging disc and the second plugging disc are smoothly, stably and safely installed in the right atrium and the left atrium in a rivet-free fixing mode correspondingly, and stable plugging of an oval foramen is facilitated. Meanwhile, the first connecting piece and the second connecting piece are respectively located in a first containing cavity and a second containing cavity, and damage of the surface of the first plugging disc and the surface of the second plugging disc to peripheral tissue is effectively avoided, so the oval foramen can be stably and safely plugged through the oval foramen unclosed plugging device.

Description

technical field [0001] The invention relates to the technical field of patent foramen ovale, in particular to a patent foramen ovale occluder, a patent foramen ovale sealing system and a method thereof. Background technique [0002] Patent foramen ovale (patentovalforamen referred to as PFO) mainly occurs during the development of young children. When the embryo develops to the 6th to 7th week, the atrial septum has two septa successively, and the septum that appears first is called the primary septum or the first septum. , The septum that appears later is the secondary septum or the second septum. The primary septum grows from the dorsal wall of the atrium midline in a half-moon shape, grows toward the atrioventricular canal and fuses with the endocardial cushion, leaving a small hole with the caudal end of the atrioventricular septum, called the primary foramen. Before the primary foramen is not closed, a hole is formed near the head of the primary septum, called the seco...

AI Technical Summary

Problems solved by technology

[0003] In order to close the foramen ovale, the traditional treatment method usually uses a PFO occluder to occlude the foramen ovale. However, because the traditional PFO occluder is fixed with a rivet structure, and the rivet structure protrudes out of the occlusion disc, so , during the occlusion process, it is easy to touch the surrounding tissue and cause damage to the surrounding tissue, thus causing complications
