The descending thoracic aorta is a part of the aorta located in the thorax. It is a continuation of the descending aorta and contained in the posterior mediastinal cavity. The descending thoracic aorta begins at the lower border of the fourth thoracic vertebra where it is continuous with the aortic arch, and ends in front of the lower border of the twelfth thoracic vertebra, at the aortic hiatus in the diaphragm where it becomes the abdominal aorta.
Thoracic aorta in-situ fenestration and whole-course brain protection integrated device and method
PendingCN121796018Ashorten the timeImprove positioning accuracyStentsBalloon catheterForeign matterThoracic aorta
The invention belongs to the technical field of medicine, and discloses a thoracic aorta in-situ fenestration and whole-course brain protection integrated device and method. According to the method, a bundling balloon is formed by a plurality of small balloons, the different small balloons are controlled to be inflated or shrunk under pressure relief, and the angle of a puncture needle is adjusted through the bundling balloon catheter. And the far-end protection umbrella covers the cluster balloon catheter and is used for preventing thrombus from escaping to the far end. According to the invention, the bundling balloon composed of a plurality of small balloons is designed, and the angle of the puncture needle is adjusted by controlling the different small balloons to expand by filling or shrink by releasing pressure, so that the time for an instrument to enter a membrane rupture window is greatly shortened, and the positioning accuracy of a membrane rupture point of the covered stent is improved; meanwhile, a far-end protective umbrella is arranged to prevent thrombus and other foreign matters from escaping to the far end.

Use of carbazole derivatives y16 for the preparation of medicaments for the treatment of cardiovascular diseases
ActiveCN117462556BGood dose-dependent vasodilationeffective treatmentCardiovascular disorderHeterocyclic compound active ingredientsPharmaceutical SubstancesLower blood pressure
The application provides application of a carbazole derivative Y16 in preparation of a drug for treating cardiovascular diseases, and belongs to the technical field of medicines.The vasodilatation activity of Y16 is determined by using a rat isolated thoracic aorta tension measurement, and the change of the vasodilatation effect of Y16 under the intervention of various channel inhibitors is observed, and the influence of Y16 on blood pressure is determined by using a rat femoral artery cannulation experiment.The results show that the carbazole derivative Y16 has a good dose-dependent vasodilatation effect, and Y16 also shows a blood pressure lowering effect, so that the carbazole derivative Y16 can effectively treat cardiovascular diseases is disclosed for the first time, the application provides a theoretical basis for obtaining a candidate compound of a drug for treating cardiovascular diseases, and also provides a new selection for a drug for treating cardiovascular diseases in clinic.
