| 摘要 |
This invention deals with monocentric, triaxial, nitrogenous epsilon-caprolactone copolyester for coating/sizing absorbable, fibrous vascular devices wherein the said copolyesters have a molecular weight of more than 20 kDa. The invention also relates to medical devices such a absorbable micro-threads as in small diameter suture braids or twisted multifilament yarn coated with absorbable, nitrogenous epsilon-caprolactone copolyester wherein the copolyester chain bears one or more carboxyl groups to which a basic polyamino acid, such as polylysine or polyarginine, is linked ionically and/or covalently.
