The invention relates to a drug eluting balloon. The drug eluting balloon comprises a balloon body, wherein the middle of the balloon body is cylindrical, the two ends of the balloon body are conical, one end of the balloon body is connected with a connecting pipe through a guide pipe, a plurality of pits are formed in the outer wall of the cylindrical middle portion of the balloon body, the elasticity modulus of each pit is smaller than the elasticity modulus of the balloon body, the elasticity modulus difference meets the conditions that the pits sink towards the interior of the balloon body when the balloon body is filled with no filing medium and the pits protrude towards the outside of the balloon body when the balloon body is filled with filling media, and by the adoption of the design, the superficial area of the balloon is increased, drug adhesion is improved, drugs are ejected in the form of a drug pill when the balloon expands, and it is guaranteed that drugs are released fully in a short time. According to the drug eluting balloon, a special structure is adopted, the drug loading capacity is improved based on a traditional drug balloon, and drugs are released fully through ejection; after the drug balloon is used, the defects of a drug support can be effectively overcome, a patient just needs to take duplex antiplatelet drugs conventionally in a short time, and the metal burden and the economical burden of the patient are greatly reduced.
