A kind of clinical freezing freezing foley's tube with treatment atrial fibrillationTechnical field
The present invention relates to technical field of medical equipment, specially a kind of clinical freezing with treatment atrial fibrillation freezes sacculus and leadsPipe.
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 withThe 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 countryTen 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, 2050Year, 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 heartRoom thrombus, embolus can cause the complication such as cerebral apoplexy after falling off, while can lead to and/or aggravate heart failure, final increase angiocarpyThe death rate of disease, maintaining sinus rhythm is still the optimum target of atrial fibrillation therapy.Drug therapy can not eradicate atrial fibrillation, can notPrevent 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 roomThe 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 complicationBottleneck.Conventional radio frequency ablation achievees the purpose that tissue damage by destroying the integrality of institutional framework, is easy to happen pulmonary veinNarrow, thrombosis and embolism, cardiac tamponade, the complication such as atrium esophageal fistula.It is safer compared with RF energy to freeze energy, freezingMore 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 formedExplosion and collagenous degeneration contracture, it is light more to retain institutional framework integrality, endothelial injuries, research shows that in cryoablation processIn, though it may occur in which that the activation of collagen does not observe lasting platelet activation, and ablation site cell surface relative smooth lightIt is whole, illustrate that cryoablation reduces the affixing probability of thrombus.Therefore a kind of clinical freezing freezing sacculus with treatment atrial fibrillation is designedConduit.
