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 belongs to the fluid measurement technology field and relates to a multiphase flow measurement method based on a double-section impedance type long waist cone sensor. The adopted sensor comprises a cone throttling element, a systolic blood pressure drop differential pressure transmitter, a permanent pressure loss differential pressure transmitter and an electrical sensitive sensor. The method comprises the following steps: collecting two pairs of differential pressure signals generated by the cone throttling element; utilizing the electrical sensitive sensor to collect an electrical signal; calculating the total mass flow rate, the each-phase mass flow rate and the each-phase mass content according to a double-differential pressure model of a single throttling element; utilizing a support vector machine to realize classify, identify and pre-judge a flow pattern according to the measurement data of the differential pressure signals and the electrical signal; adopting a capacitance model to measure a mixed fluid dielectric constant; adopting a conductivity model to measure the mixed fluid conductivity; and calculating the procedure parameter of oil-gas-water three-phase flow. The multiphase flow measurement method is not influenced by the fact that whether a multiphase flow continuous phase is conducted or not, has the characteristics of high measurement precision,high reliability and the like and can obtain more measurement information.

The invention discloses a postoperative patient supervision system for neurointerventional therapy, relates to the technical field of postoperative patient supervision, and is used to solve the problem that the existing postoperative patient supervision of neurointerventional therapy cannot supervise the patient's physical characteristic data Analyze and adjust the patient's infusion speed, which is prone to infusion reaction problems; including a supervision module and an adjustment module, the supervision module sends the physical characteristic data to the server, and analyzes it at the same time to obtain an adjustment signal; After the order, the adjustment signaling is analyzed to obtain the adjustment distance, and the adjustment module is triggered to adjust the rate of patient infusion through the adjustment distance; the present invention monitors and analyzes the data of postoperative patients undergoing nerve intervention therapy through the supervision module to obtain the adjustment distance; through the adjustment distance Reasonably adjust the infusion speed of patients after neurointerventional therapy; avoid problems such as blood pressure drop and body temperature rise caused by too fast infusion.
