Embodiment Construction

[0016] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0017] Such as Figures 1 to 4 As shown, a drug-eluting balloon includes a balloon body 2, the middle part of which is cylindrical, and the two ends are conical. One end of the balloon body 2 is connected to the connecting tube 1 through a catheter 3, There are several depressions 4 on the outer wall of the cylindrical middle part of the balloon body 2, the modulus of elasticity of the depressions 4 is smaller than that of the...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of drug eluting tools, in particular to a drug eluting balloon. Background technique [0002] In the past 10 years, with the emergence of drug-eluting stents, the clinical problems of most patients have been solved. However, the formation of late thrombosis and in-stent restenosis, prolonged endothelial healing time due to slow-release drug-coated stents, limited treatment of small vessel lesions and bifurcation lesions, and the need to take dual antiplatelet drugs for 1 year after surgery And other problems also seriously restrict the clinical benefits of drug-eluting stents. The emergence of drug balloons has successfully overcome these defects of drug stents. Moreover, after the application of the drug balloon, the patient only needs to routinely take dual antiplatelet drugs for a short period of time, which greatly reduces the financial burden on the patient. Contents of the invention [0003] The t...
