POST ELECTRON BEAM CONDITIONING OF POLYMERIC MEDICAL DEVICES |
摘要 |
Methods are disclosed for conditioning a polymeric stent after sterilization, and/or after crimping and before packaging, such that the properties of the polymeric stent fall within a narrower range of values. The stent is exposed to a controlled temperature at or above ambient for a period of time after radiation sterilization and/or after crimping and before sterilization. As a result, the polymeric stent properties, particularly radial strength and number- average molecular weight of the polymer of the polymeric stent, fall within a narrower range. |
