약물 전달 장치 및 이의 제조방법

Abstract

A drug delivery device and a method for manufacturing the same, and more specifically, a drug delivery device that can deliver a drug to a biological tissue while minimizing damage thereto and can come into close contact with the biological tissue to be able to measure an electrical signal of or apply electrical stimulation to the biological tissue and a method for manufacturing the drug delivery device are proposed. The drug delivery device includes a substrate unit that is inserted into a human body and has a porous insertion portion having one or more discharge voids. The insertion portion is provided to be deformable to match a shape of a biological tissue while expanding and contracting as a drug is injected into and discharged from an inside of the injection portion.
