  • Analysis of factors affecting polymer performance, including surface and bulk properties.
  • Examination of degradation rates for bioabsorbable polymers.

Main Results:

  • Performance of synthetic polymers in vascular applications is influenced by secondary characteristics.
  • Surface properties (roughness, porosity, contaminants) are critical.
  • Bulk properties, fragmentation, and degradation rate (for bioabsorbable polymers) are significant factors.

Conclusions:

  • Understanding secondary characteristics of synthetic polymers is crucial for vascular applications.
  • Knowledge of stent healing characteristics is essential for successful long-term outcomes.
  • Further research into polymer-tissue interactions is needed.
