Bioabsorbable Polymeric Compositions and Medical Devices |
| abstract |
The present invention comprises a stent comprising a blend formed from a polymer. The polymer comprises poly-L-lactide, poly-D-lactide or mixtures thereof and a copolymer moiety comprising poly-L-lactide or poly-D-lactide linked with ε-caprolactone or trimethylcarbonate. The poly-L-lactide or poly-D-lactide sequence in the copolymer moiety is random with respect to the distribution of ε-caprolactone or trimethylcarbonate and the copolymer moiety molecular weight ranges from about 1.2 IV to about 4.8 IV. The meandering elements may be stretched to a modulus ranging from about 250000 PSI to about 550,000 PSI. One, two, three, n or all segments of the meandering element may have a decreased cross-sectional area and may have a wide-angle X-ray scattering (WAXS) 2θ values of ranging from about 1 to about 35 after stretching. The crystal properties of the bioabsorbable polymers may change during crimping and/or expansion allowing for improved mechanical properties such as tensile strength and slower degradation kinetics. |
