<p>A stent to be implanted in a blood vessel. The stent (1) is made of a biodegradable polymeric material (2). The stent (1) is swollen and a sufficient amount of a drug is fixed to the swollen stent (1). Thus, the drug is continuously released into a blood vessel over long. A biodegradable polymer layer may be formed on the surface of the stent (1) having a drug fixed thereto to thereby control the rate of release of the drug fixed to the stent.</p> |
