In this study, we are processing bioabsorbable polymer tubes required for bioabsorbable vascular scaffold (BVS) processing. As a bioabsorbable stent that can maintain blood vessel for a certain period of time and be absorbed in the body is being developed. Bioabsorbable polymer(PLLA) tubes have diameters and tolerances (±0.05 mm) of 2.50 ~ 3.50 mm, and wall thickness of 200 ㎛ with tolerance of ±10 ㎛. Stents have a mechanical strength of 300 MPa because they need the strength to support the blood vessels. This work was supported by the Korea Medical Device Development Fund grant funded by the Korea government (the Ministry of Science and ICT, the Ministry of Food and Drug safety) (Project Number: KMDF_PR_20200901_0005,9991006678), This research was financially supported by Jeollanam-do, Korea, under Regional Specialized Industry Development Program of Next-generation stent innovative processing advance technology support project (R&D, B0080621000341). |
