Abstract:
The present invention relates to a drug-releasing biodegradable stent. The drug-releasing biodegradable stent includes: a first stent structure configured to have a plurality of cells by means of the wire crossing pattern of a woven structure and be provided in a hollow cylindrical shape by weaving a metal wire made of a shape-memory alloy in a specific pattern on a jig; and a second stent structure formed as a 3D print that is provided to have a plurality of cells by means of the wire crossing pattern of a printed structure and also have a hollow cylindrical shape by performing 3D printing using a printing material including a biodegradable polymer and a drug, and disposed such that it covers the outer circumferential surface of the first stent structure or the outer circumferential surface thereof is covered with the first stent structure.
