  • Patent number: 11819227
    Abstract: Provided are a treatment method, a separation method, and a filter assembly capable of preventing so-called “Blue Toe syndrome” which is so-called cholesterol crystal embolism of which a fat-soluble compound such as cholesterol crystals generated during dilation of a stenosed site causes clogging in glomeruli of peripheral capillaries or kidney, acute renal failure, and the like. Cholesterol crystals generated from plaque during use of a balloon catheter are taken out of the body and removed using a centrifugal separation device or a filter, and usable living cells are returned to the body to reduce blood transfusion and reduce cholesterol crystal embolism.
