PURPOSE: A catheter for extracting foreign materials is provided to enhance extraction of foreign materials by enabling a body portion of the catheter to transfer along a vessel. CONSTITUTION: A catheter for extracting foreign materials comprises a body portion(100) which is made of flexible material and inserted into a blood vessel, a separation unit(200) which is placed in the body portion to enter through a first opening, and a suction unit which inhales foreign materials absorbed from a mesh and the separate unit using suction force offered through a second opening. The body portion comprises the first opening which is formed in one end, and a second opening which leaks air coming from the first opening using suction force offered from outside. The separation unit comprises a streamlined mesh which cross-sectional area gets smaller towards the front and can accept foreign materials of the blood vessel in circumference area.
