Abstract
Description
Technical Field
The embodiments of the application belong to the field of instruments for clinical operations, and more particularly, relate to a heart foramen ovale plugging device.
Background
The foramen ovale is a small hole in the septum of the left and right atria, located in the middle and lower part of the atrial septum, and is a "flap-valve-like" structure formed by the inferior border of the secondary septum and the primary septum, through which oxygenated placental blood can pass during pregnancy to the fetal arterial circulation, an important physiological pathway. After birth, with the rise of left atrial pressure, functional closure of the foramen ovale occurs, anatomical closure is achieved within one year, the foramen ovale is not closed beyond three years old and is called as Patent Foramen Ovale (PFO), and the incidence rate of PFO in adults is 25% -33% through investigation.
PFO directly causes right-to-left shunting of the heart, but PFO has long been considered to have no clinical consequence due to its too small shunt volume. In recent years, more and more researches show that the risk of patients with PFO suffering from cerebral apoplexy, migraine, peripheral arterial embolism, decompression sickness and the like is increased by several times compared with normal people, and the pathogenic effect of PFO causes the attention of extensive experts and scholars.
At present, the clinical application mainly uses a catheter instrument to convey the occluder to the position of the foramen ovale to mechanically occlude the foramen ovale.
The existing occluders basically comprise two elastic disk parts, and when the occluders are used, the two disk parts are respectively attached to the next walls of the left atrium and the right atrium so as to realize occlusion of the foramen ovale. For example, chinese patent ZL202011619405.5 discloses a degradable patent occluder for cardiac patent foramen ovale and a method for manufacturing the same, the occluder is composed of a flow-blocking member, a tubular portion, a connecting member and two disk portions, and the tubular portion and the two disk portions are woven by using an elastic net. When the occluder is used clinically, the occluder is usually conveyed to a foramen ovale area by a conveying pipe, then released, and attached to the atrial septal wall of the left atrium and the right atrium through the elastic tension of the elastic net, so that the aim of sealing the foramen ovale is fulfilled.
The current plugging device lacks tightening part and supporting component, because the difference of each person of the form of oval hole is very big, only relies on the elastic tension of elasticity net self to warp after the plugging device implantation and resets, can't guarantee to laminate heart room interval completely at every turn, leads to can not the complete shutoff oval hole, and this has just caused postoperative oval hole still has remaining reposition of redundant personnel. In addition, the occluder belongs to foreign matters in the heart, and in the long-term implantation process, the tissue cells can gradually cover the foreign matters, which is called endothelialization process. However, this greatly prolongs the endothelialization process since the occluding device does not fully conform to the atrial septum after implantation. The occluder made of degradable materials can be degraded in a certain time after being implanted, and if the endothelialization process is not completed after degradation, the process is equivalent to that the foramen ovale is not occluded, so that the operation fails.
