Embodiment 1

[0074] According to the method for forming vascular embolism in non-human animals of the present invention, a miniature pig myocardial infarction model is prepared, specifically as follows:

[0075] (1) After weighing the miniature pigs, give ketamine 10-15 mg / kg, midazolam 0.2-0.4 mg / Kg, and atropine 0.03 mg / Kg intramuscularly. After about 5-10 minutes, the miniature pig could not stand still and fainted. After cleaning, the embolized area was depilated, and the ear vein channel was established. Ketamine 8 mg / kg.h was continuously injected intravenously by a micropump.

[0076] (2) Send the minipig into the catheterization room, fix it on the V-shaped groove in the supine position, place it on the catheter bed, perform ECG monitoring, oxygen inhalation, and pulse oxygen monitoring to monitor the oxygen saturation, and take insulation measures at the same time. The bilateral femoral artery puncture area was routinely disinfected and draped, the femoral artery was percutaneou...

Abstract

The present invention proposes devices, systems and uses for forming vascular embolizations. Wherein, the device is a "sandwich" structure threaded on a guide wire, comprising: a guide wire, the guide wire is defined with a head end and a tail end; a first hemisphere balloon, the first half The center of the balloon body has a first hemispherical cavity, and the first hemispherical body is sheathed on the guide wire through the first hemispherical cavity; The center of the second hemispherical balloon has a second hemispherical cavity, and the second hemispherical balloon is sleeved on the guide wire through the second hemispherical cavity; the sponge, the sponge A body is arranged between the first hemisphere balloon body and the second hemisphere balloon body, and the guide wire passes through the cavernous body; and a push rod, the push rod and the second hemisphere The balloon bodies are connected as a whole. The device can effectively embolize blood vessels, and can precisely control the embolization level.

Description

technical field [0001] The invention relates to the field of medical instruments. In particular, the present invention relates to devices, systems and uses thereof for forming vascular embolisms. More specifically, the present invention relates to devices, systems and uses thereof for forming vascular embolisms in non-human animals, methods for forming vascular embolisms in non-human animals, and embolized coronary artery preparations for screening pro-angiogenic Novel Drug Approaches to Large Animal Models of Myocardial Infarction. Background technique [0002] Cardiovascular disease is a major disease that threatens human life and health today, and ischemic heart disease is the focus of cardiovascular disease. According to statistics released by WHO in 2011, about 7 million people die from ischemic heart disease every year, accounting for 12.8% of all causes of death. According to the forecast of the World Health Organization experts, from now to 2030, myocardial infarc...
