  • Patent number: 12290615
    Abstract: A drug coated balloon includes a balloon body and a drug loaded coating layer. The drug loaded coating layer includes a first drug loaded coating component having at least two controllable sustained release drugs with different drug release kinetics, and a second drug loaded coating component including an active drug. The second drug loaded coating component is dispersed among the controllable sustained release drugs and couples the controllable sustained release drugs on the balloon body. The first and second drug loaded coating components are both non-hydrophilic compositions. The drug coated balloon provides sufficient initial drug loading dosage to the lesion site, and has adjustable drug release rate, thereby allowing the drug coated balloon to provide bioactive drugs to the treatment site at different stages of the cascade reaction of vascular restenosis, providing the controllable long-acting therapeutic drugs, and improving the overall vascular drug release efficacy.
