    摘要: A luminal stent, implanted and implanted and left in the blood vessel, is disclosed. By permitting a stent (1), formed of a biodegradable polymer material (2), to be swollen, and by impregnating the swollen stent (1) with a drug, a sufficient quantity of the drug is impregnated in the stent. This drug is continuously released into the blood vessel over a prolonged time. A biodegradable polymer layer is formed on the surface of the stent (1) impregnated with the drug, and the release rate of the drug impregnated in the stent is controlled.

    摘要: The present invention is relative to a melt spinning apparatus for melt spinning a biodegradable polymer material. The biodegradable polymer material is melted by a melt mechanism (4) including a screw (16) which is mounted in a vertically mounted cylinder (8) coaxially with the cylinder (8) and which is rotationally driven by a rotational driving mechanism (7). The screw includes at least one turn of a helical groove (17) on its peripheral surface. The biodegradable polymer material being melted in this way is discharged in the vertical direction from a discharge opening of a nozzle (10) mounted coaxially on the cylinder (8).
