In a method for diagnosing and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a lesion distal to an aortailiac bifurcation is to be treated first, catheters and an operation time can be reduced. The lesion to be treated first can be on a priority basis based on diagnostic data, deciding that a lesion proximal to the bifurcation is to be treated next, and then treating the lesions substantially continuously.

Diagnostic method, method for validation of diagnostic method, and treatment method

A method for diagnosing, validation of diagnosis and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a larger vessel diameter lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a smaller vessel diameter lesion is to be treated next, then treating the lesions substantially continuously.

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.

Treatment method, separation method, and filter assembly

In a method for diagnosing and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a larger lesion curvature to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a smaller lesion curvature is to be treated next, then treating the lesions substantially continuously.
