Methods and devices are provided for protecting the cerebrovascular circulation from embolic debris released during an index procedure. An embolic protection filter is delivered in a reduced profile configuration via an access catheter, and positioned in the aorta spanning the ostia to the three great vessels leading to the cerebral circulation. An index procedure catheter is thereafter advanced through the same access catheter to conduct the index procedure. The index procedure may be a transcatheter aortic valve replacement. A pore distribution in the filter blocks passage of debris greater than a predetermined threshold, minimizes total cumulative volume of debris passing through the filter and minimizes blood pressure drop across the filter.

The invention discloses a novel hypertension model and establishment and application thereof. According to the novel hypertension model, a rat is selected as an experimental animal, atlantoaxial joint disorder is mechanical equilibrium stability damage, and compared with a model obtained through other methods (drug Freund's complete adjuvant and manual resistance rotation), the success rate is high, and the blood pressure rising trend is most obvious. According to the invention, the atlantoaxial lateral joint internal metal built-in object (which is beneficial to radiography development and fixation) is adopted, and after the built-in object in the atlantoaxial joint is further taken out, the atlantoaxial lateral joint internal metal built-in object simulates manual reduction, so that the blood pressure drop can be observed. The invention can be used for further research on hypertension caused by atlantoaxial joint disorder in the later period.
