- Biodegradable polymeric stents have been issued to replace the existing non-degradable metal
stents due to relatively improved biocompatibility and low side effects. Fundamentally, all the stents must
possess the desired mechanism strength, especially, compression force or radial force to maintain the
diameters of expanded vessels. Therefore, this study suggests the helical structure and focused on the
relation between the lateral compression and structural factors. Unlike a cylindrical model, the radial force
of the helical model is proportional to the thickness and the length in 1 order of magnitude, whereas the
diameter in 1.6 order. The function obtained from these results might provide the fundamental information
to design and prepare the stent for clinical applications.
