Embodiment Construction

[0027] Such as figure 1 It is a cross-sectional view of the occluder for ventricular septal perforation after myocardial infarction. An embodiment of the present application provides a post-myocardial infarction ventricular septal perforation occluder, the post-myocardial infarction ventricular septal perforation occluder 10 includes: a first disc 100, used to fit the left ventricle and the interventricular septum, the second The first disc 100 is arc-shaped; the second disc 200 is used to fit the right ventricle and interventricular septum; the waist 300 is connected to the first disc 100 and the second disc 200 .

[0028] When the above-mentioned ventricular septal perforation occluder 10 after myocardial infarction is in use, a hole is punched through the surface of the heart and implanted in the human body. The first disc is attached between the left ventricle and the interventricular septum, and the second disc is attached between the right ventricle and the Between the ...

Abstract

The invention relates to an interventricular septum perforating stopper used after miocardial infarction. The interventricular septum perforating stopper used after miocardial infarction comprises a first disk for being jointed with a left ventricle and an interventricular septum, a second disk for being jointed with a right ventricle and the interventricular septum, and a waist part for connecting the first disk with the second disk, wherein the first disk is arc. According to the interventricular septum perforating stopper used after miocardial infarction disclosed by the invention, the first disk is arc, and the first disk is in arc-shaped jointing with the left ventricle and the interventricular septum, so that the shearing force between the first disk and the left ventricle and the shearing force between the first disk and the interventricular septum are reduced, abrasion is reduced, the jointing property between two sides of the interventricular septum perforating stopper used after miocardial infarction and the left ventricle and the interventricular septum is better, tissue regeneration endothelialization is facilitated, the situation that residual branching, haemolysis and mural thrombus complications are generated on a patient is avoided, the surgery cure rate is increased, and the pain of the patient is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to an occluder for a ventricle septum perforation after myocardial infarction. Background technique [0002] Ventricular septal perforation is one of the serious complications after acute myocardial infarction, and about 10% of cardiac ruptures caused by acute myocardial infarction are located in the ventricular septum. In the pathological and anatomical data of death cases due to acute myocardial infarction, the incidence of ventricular septal perforation is 1.3%-2%. Perforation of the ventricular septum causes rapid hemodynamic changes, which seriously threatens the life of the patient and often leads to death within a short period of time after the onset of the disease. 25% of patients died within 24 hours after the onset, 50% died within one week, 70% died within two weeks, and only 20% survived for more than one month after the onset. [0003] In order to treat ventricular septal perforati...
