Poly(ester urea) fiber devices and related methods

Disclosed are bio-absorbable polymers that may be formed into fibers and sterilized in a manner that does not substantially affect the morphology of the fibers during the sterilization process. Such sterilized polymer fibers may have use as a bioabsorbable scaffold for implantation in a patient. In one embodiment, electron beam irradiation is used in the sterilization process.
