摘要：

A method to reduce or minimize the reduction in molecular weight of a stent during processing is disclosed. The stent has a scaffolding including a polymer formulation comprising PLLA and polymandelide. The polymandelide reduces the molecular weight drop during processing, particularly during sterilization. The stent scaffolding can further include one or more additional stabilizing agents that additionally reduce the molecular weight drop during processing.
