Structural Design on Biodegradable Magnesium Alloy Vascular By Biodegradable Balloons

Yafei Guan

Thinner biodegradable magnesium alloy stents, also known as BMgSs, enable quicker endothelialisation to postpone deterioration and improved clinical efficacy. However, because to their low elastic modulus and eventual elongation, thin walled BMgSs constructions are more vulnerable to problems than conventional non-degradable stents, including inadequate support capacity and breakage, during rapid expansion. This work optimised a thin-walled BMgSs structure. Our BMgSs was built using a ZE21B alloy with a high breaking elongation and superior mechanical qualities. Response surface models and an optimised configuration were used to optimise the support ring structure of a typical stent Bio Matrix using finite element analysis. Obtained from a BMgSs with a thin wall. The initial thick-walled stent, which was 150 lm thick, had a radial strength equivalent to the optimised thin-walled stent, which was 100 lm thick.
