Description
Technical field
The present invention relates to technical field of medical equipment, specially a kind of clinical freezing with treatment atrial fibrillation freezes sacculus and leads
Pipe.
Background technique
Atrial fibrillation is clinically one of most common arrhythmia cordis, it is estimated that there are about 1% with atrial fibrillation in total population, and with
The growth disease incidence at age and increase.According to reckoning, there are about 3,000,000 populations at present in the U.S., has about 450 in EU member country
Ten thousand people suffer from atrial fibrillation, at the same time, annual to have about 600,000~800,000 new cases that this ranks is added again.By this supposition, 2050
Year, suffering from atrial fibrillation, person has a surplus twice of the existing number of increasing.Our national at least 8,000,000 patients with atrial fibrillation.Atrial fibrillation easily causes the heart
Room thrombus, embolus can cause the complication such as cerebral apoplexy after falling off, while can lead to and/or aggravate heart failure, final increase angiocarpy
The death rate of disease, maintaining sinus rhythm is still the optimum target of atrial fibrillation therapy.Drug therapy can not eradicate atrial fibrillation, can not
Prevent its generation, long-term effect is bad.The operation of atrial fibrillation catheter ablation is the preferred means of atrial fibrillation therapy, but it treats room
The surgical procedure to quiver is cumbersome, and learning curve is very long and a height of this Technique Popularizing of incidence of recurrence after operation rate and complication
Bottleneck.Conventional radio frequency ablation achievees the purpose that tissue damage by destroying the integrality of institutional framework, is easy to happen pulmonary vein
Narrow, thrombosis and embolism, cardiac tamponade, the complication such as atrium esophageal fistula.It is safer compared with RF energy to freeze energy, freezing
More evenly, boundary is apparent, and does not cause the relevant eschar of high-temperature effect, gasification for the tissue damage internal fibrillation that energy is formed
Explosion and collagenous degeneration contracture, it is light more to retain institutional framework integrality, endothelial injuries, research shows that in cryoablation process
In, though it may occur in which that the activation of collagen does not observe lasting platelet activation, and ablation site cell surface relative smooth light
It is whole, illustrate that cryoablation reduces the affixing probability of thrombus.Therefore a kind of clinical freezing freezing sacculus with treatment atrial fibrillation is designed
Conduit.
