Professor Alexander M. SeifalianThe Singularity Hub article Nanotechnology Creates Artificial Artery for Clinical Trials said
Researchers at London Royal Free Hospital are hoping to save limbs and lives with the creation of their new artificial artery. Unlike current artery replacements, this grafting substance was created using nanotechnology and can pulse with the natural movements of the body. That pulsing will allow the polymer tube to be used in very small grafts (<8mm), giving hope that damaged arteries which would normally lead to amputations or heart attacks can now be treated. According to a recent press release, the Wellcome Trust has given [L]$500,000 to begin clinical trials of the new artificial arteries by the end of 2010. We could see the new polymer arteries in grafts, stints, and other vascular surgeries in the next few years.
The new artificial artery material was developed by Professors George Hamilton (vascular surgery) and Alexander Seifalian (nanotechnology and tissue repair). The substance is a polymer which has been embedded with different types of special molecules. Some of these molecules aid circulation, others encourage stem cells to coat its walls. That coating is very important and may allow the artificial tissue to bond better with the body and promote long term health. Most importantly though, the design of the artificial vascular tissue is resistant to clotting and can pulse.
