A research team at KIST has developed a novel stent surface treatment technology using laser patterning to promote endothelial cell growth and inhibit smooth muscle cell dedifferentiation in blood vessels. Traditional metal stents may cause restenosis, leading researchers to explore surface coatings with bioactive molecules. The team applied nanosecond laser texturing to create wrinkle patterns on stent surfaces, effectively reducing smooth muscle cell growth while enhancing endothelialization. This technology has potential applications for both metal and biodegradable stents, improving treatment outcomes and reducing complications. The team plans to conduct further animal tests and clinical trials to verify the safety and efficacy of this innovative surface patterning technology.
