Description
Technical field
The present invention relates to the field of medical instrument technology, specifically, being a kind of fixation device of Therapy of Left Ventricular Aneurysm and its being
System.
Background technique
After myocardial infarction, downright bad cardiac muscle is gradually substituted by fibrous scar tissue, and locular wall is thinning, outside bulging, is formed
Aneurysm increases bulk of left ventricle, aggravates the preload of left ventricle, lead to cardiac insufficiency.Aneurysm is most commonly in left ventricle.It is interior
Section's drug therapy and surgery left ventricular volume reduction are clinically used treatment methods.Surgery left ventricular volume reduction is curative for effect, but
Operating difficulty is big, risk is high, and perform the operation case fatality rate and complication rate are high, and to the more demanding of patient, clinical application by
Limit；And medical curative effect is not good enough.
Surgery ventricular aneurysmectomy or surgery aneurysm fundoplication at present need mid-sternal incision, cut breastbone, and
The complex operations such as extracorporal circulatory system are needed, patient restores slow, and risk is big, and intervention aneurysm fundoplication can generate bulk of left ventricle
It reduces, cardiac output is caused to reduce, damage heart function.
Interventional therapy method:
1, Parachute art (parachute technology) may cause cardiac rupture, and aneurysm blocks not exclusively, and malignant cardiac rhythm loses
Normal and sudden cardiac death etc., stopped at clinical use by U.S. FDA in 2017.
2, left ventricle Reconstruction --- Revivent TC (left room fundoplication) is at present in clinical test rank for minimally invasive joint intervention
Section, but bulk of left ventricle can be reduced and make it below normal value, cardiac ejection amount is reduced, and heart function cannot effectively improve.

Technical problem:
The present invention and above-mentioned 2 kinds of therapeutic modalities are entirely different, by the minimally invasive method intervened of combining by the aneurysm of bulging
It is fixed, in ventricular systole not bulging, reduces bulk of left ventricle but be not less than normal value, increase left room output quantity, improve heart and penetrate
Blood function.
Summary of the invention
It is an object of the present invention to provide the fixation devices and its system of a kind of Therapy of Left Ventricular Aneurysm.
To achieve the above object, the technical solution adopted by the present invention is that:
