Prosthetic News and Research

RSS

Prosthetic (Prosthesis) devices, such as an artificial leg, that replace a part of the body. Prostheses are typically used to replace parts lost by injury (traumatic) or missing from birth (congenital) or to supplement defective body parts. Inside the body, artificial heart valves are in common use with artificial hearts and lungs seeing less common use but under active technology development. Other medical devices and aids that can be considered prosthetics include artificial eyes, palatal obturator, gastric bands, and dentures.

Nanomatrix stent coating designed to mimic natural endothelium

A nanomatrix for stent coating designed at the University of Alabama at Birmingham (UAB) mimics natural endothelium, the substance that lines blood vessels, and promises the potential to prevent post-operative tissue scaring along the blood vessel wall, greatly reducing the possibility of future thrombosis, or blockage at the stent site.
