Corrugated Biopolymeric Grafts: A Multifunctional Approach to Vascular Reconstruction and Hemodynamic Optimization

Vascular grafts have a significant role in the artery replacement, aneurysm repair, and hemodialysis treatments. Synthetic grafts that have been mostly used in the clinic include ePTFE and Dacron; however, their use has been associated with a range of complications that include clot formation, intimal hyperplasia, and infections. Corrugated Biopolymeric grafts are one of the promising options that were introduced in the market due to their relatively higher biocompatibility and mechanical advantages. There is still a need to find the right choice regarding mechanical strength, fluid flow, and effective antimicrobial activity. The given research explores the mechanical response of the physiological pressure in corrugated biopolymeric grafts in order to improve antimicrobial activity. These grafts were manufactured and stimulated with the help of COMSOL Multiphysics ® 6.2 with an aim to determine the pattern of stress distribution, resistance to pulsatile pressure, and fatigue behavior during dynamic flow. The result was that the corrugated structure showed superior mechanical strength and had better compliance with natural blood vessels, which consequently might improve antimicrobial activity.
