Description
Technical field
The present invention relates to a kind of substitute of tissue and its implanted device, and in particular to one kind has biasing release knot
The insertion type artificial cardiac valve conveying device of structure.
Background technology
Heart is the most important organ of human body, and heart is divided into left and right two parts, and each section includes atrium and ventricle again.It is left
Atrium dextrum and left and right ventricles are separated by atrial septum and interventricular septum respectively.Four cardiac valves, i.e. tricuspid valve, lung in heart be present
Arterial valve, bicuspid valve and aorta petal.In blood circulation of human body system, four cardiac valves play vital effect.
The anoxic blood of systemic circulatory system enters atrium dextrum through vena cave, then enters right ventricle by tricuspid valve, right ventricle shrinks will
Blood is pressed into systemic pulmonary circulation by pulmonary valve, and the blood after lung oxygen saturation returns to atrium sinistrum through pulmonary vein, then through two
Cusp reaches left ventricle, and blood is discharged into sustainer to return to systemic circulatory system by left ventricular contraction by aorta petal.Sustainer
There is left and right coronary ostium under valve.Valve-open when four valvular structures ensure that blood clockwise direction, reverse direction
When close, it is therefore prevented that heart burden caused by blood reflux.But due to a variety of causes, cardiac valves can be caused
Posteriority damage or lesion, such as rheumatism, atherosclerosis etc..In addition, congenital heart disease such as fallot's disease, postoperative
Long term can also produce cusps of pulmonary valve lesion.Valvular function is shown as after valve lesion gradually to lose, as valvular inadequacy is led
Blood reflux is caused, valvular stenosis causes blood circulation not smooth, or incompetence and the two narrow merger, is born so that aggravating heart
Load, causes cardiac failure.It is out chest, heart for the damage of valvular posteriority or lesion, traditional treatment method
After stoping jumping, under Hypothermic Cardiopulmonary Bypass support, open the surgical repair of heart progress diseased valve or manually cardiac valves is put
Change.Existing heart valve prosthesis is divided to two major classes：Metal machinery valve and biovalve.Biovalve is quiet by bovine pericardium, ox neck
It is made after the processing of the animal materials such as arteries and veins valve, porcine aortic valve.
Generally, it is the open openheart surgery carried out under general anesthesia that cardiac valves, which changes operation, in the process the heart
It is dirty stopping and blood flow controlled by cardiopulmonary bypass machine.Traditional open surgery causes significant patient trauma and uncomfortable, and
Expose patients to a variety of potential dangerous, such as infection, apoplexy, kidney failure and for example associated with the use of cardiopulmonary bypass machine
Detrimental effect.
The shortcomings that due to open surgery step, increasingly interested is valvular minimally-invasive and percutaneously puts
Change.By means of being percutaneously compacted to be delivered in conduit, then for example being moved by stock through conduit (or puncture) technology, valve prosthesis
Opening in arteries and veins simultaneously proceeds to heart by descending aorta, and then prosthese is in valve annulus (for example, aortic valvular ring) to be restored
Interior deployment.Although being opened relative to traditional support is conveyed to recover vascular, extensive receiving has been obtained through microcatheter technology,
In the case of entering percutaneous conveying for more complicated prosthetic heart valve, this only has mixing resultant.Prosthetic heart valve
All kinds and construction can be used for percutaneous valve replacement process, and sustained improvement.
