Abstract
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.
