Coating Techniques and Release Kinetics of Drug-Eluting Stents

Drug Release Analysis and Optimization for Drug-Eluting Stents

The drug release analysis and optimization for drug-eluting stents in the arterial wall are studied, which involves mechanics, fluid dynamics, and mass transfer processes and design optimization. The Finite Element Method (FEM) is used to analyze the process of drug release in the vessels for drug-eluting stents (DES). Kriging surrogate model is used to build an approximate function relationshi...

Mathematical Modeling and Simulation of Intravascular Drug Delivery from Drug-Eluting Stents with Biodegradable PLGA Coating

Drug-eluting stents (DES) are commonly used in coronary angioplasty procedures. A DES elutes drug compounds from a thin polymeric coating into the surrounding coronary artery tissue to reduce in-stent restenosis (a significant lumen loss due to growth of vascular tissue). Biodurable (non-erodible) polymers are often used in the current DES coatings, which stay permanently in the patients. While...

Modeling and analysis of drug-eluting stents with biodegradable PLGA coating: consequences on intravascular drug delivery.

Increasing interests have been raised toward the potential applications of biodegradable poly(lactic-co-glycolic acid) (PLGA) coatings for drug-eluting stents in order to improve the drug delivery and reduce adverse outcomes in stented arteries in patients. This article presents a mathematical model to describe the integrated processes of drug release in a stent with PLGA coating and subsequent...

New Drug-Eluting Stents

The introduction of drug-eluting stents (DES) has rapidly and profoundly affected the field of interventional cardiology, and DESs are now used in a majority of intracoronary stenting procedures. As a result of the innumerable “trial-and-error” endeavors, DESs have emerged as a potential solution for solving the problem of restenosis. DESs are coated stents capable of releasing single or multip...
