Abstract  

The sirolimus--releasing PLA--PTMC coating was successfully prepared on the biodegradable AZ31B magnesium alloy coronary stents. The surface morphology, degradability, biocompatibility and drug release characteristic of the coating were also evaluated. The results indicated that PLA--PTMC used as the drug elution coating showed good flexibility with smooth and uniform surface, the degradation period was over one month, and the biocompatibility was excellent. The drug--loaded coating had releasing function of sirolimus and the releasing time was more than one month, which could effectively inhibit the restenosis during the period of intima hypertrophy. The sirolimus--releasing PLA--PTMC coating showed potential to be used as a new type of coronary stent coating. 

Key words:  organic polymer materials      drug--eluting coronary stent      drug--loaded coating      polylactic acid--polytrimethylene carbonate copolymers
