摘要

The present invention relates to a drug delivery device, which comprises a microneedle, and which is to be attached to the exterior wall of a vascular vessel, and to a drug delivery method, and more specifically, to a drug delivery device, which is to be attached to the exterior wall of a vascular vessel and to a drug delivery method using same. The drug delivery device comprises: a) a biocompatible device body for surrounding a vascular vessel; b) one or plurality of biocompatible microneedle, which are connected to the interior of the biocompatible device body and capable of penetrating up to the tunica media so as to deliver drug to the smooth muscle cells. The drug delivery device and method according to the present invention enable spatial and temporal control of the drug ejected onto the blood cells and enable insertions of two or more different drugs at different delivery speeds and durations, thereby significantly improving the treatment success rate.
