Description

DEVICE FOR REMOVING INTRAVASCULAR LIPIDS TECHNICAL FIELD

[0001] The invention relates to a device for removing intravascular lipids.

BACKGROUND

[0002] At present, hyperlipidemia is a common clinical disorder of lipid metabolism, which usually refers to the increase of cholesterol (or) triglycerides in plasma, which easily results in diseases such as coronary heart disease and atherosclerosis. The level of blood lipids is closely related to daily dietary intake and lipid metabolism in the body. Due to the changes in modern lifestyles, such as excessive or unbalanced nutritional intake, office workers sitting in the office for a long time so that the amount of exercise is insufficient, with changes in the pace of life and diet structure, the incidence of hyperlipidemia is rising sharply, which seriously threatens human health.

[0003] At present, western medicines commonly used to treat hyperlipidemia on the market comprise statins, fibrates, etc., as well as proprietary Chinese medicines such as Xuezhikang, Jiangzhiling and Zhibituo. Although the lipid-lowering drugs have achieved great effects, most lipid-lowering drugs are prone to cause various side effects: for example, taking statins will cause adverse reactions such as increased serum transaminases and muscle aches; it more likely for those taking clofibrate to develop gall-stones or tumors; taking other proprietary Chinese medicines, etc, will also cause a burden on the liver in the long run and require a higher cost for long-term use.

[0004] No matter which method is used to lower blood lipids, it is to inhibit the formation of lipids to achieve the purpose of lowering lipids, which will bring greater side effects. At present, no effective method or device for rapidly lowering lipids after formation of cholesterol (or) triglycerides has been developed. The deposition of lipids is controlled at the terminal, thereby reducing the chance of modern people suffering from cerebral cardiovascular diseases.
