Recent Findings from University of Oxford Has Provided New Information about Biomedicine and Biomedical Engineering

May 7, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Fresh data on Biotechnology are presented in a new report. According to news reporting out of Oxford, United Kingdom, by NewsRx editors, research stated, "Brain arterial aneurysms are localised dilatation in the wall of cerebral arteries that are common among adult population and associated with high incidence of morbidity and mortality. Using flow diverter stent alone to treat cerebral aneurysm is recognized as a safe and effective method."

Our news journalists obtained a quote from the research from the University of Oxford, "However, flow diverter stents currently available have limitations due to their braided structures. In this paper a novel flow diverter stent is proposed. It is made out of nitinol tubes that provide adequate radial stiffness and tailored surface coverage to overcome problems of currently available braided stents while retaining low porosity and excellent longitudinal flexibility. Finite element analysis using Abaqus has been conducted to investigate radial stiffness, longitudinal flexibility, and maximum strain during packaging of a series of novel stent designs with varied geometric parameters. Results show that porosity below 70% can be achieved and provides radial stiffness and longitudinal flexibility comparable to those of the Neuroform stent that is commonly used for stent assisted coiling."

According to the news editors, the research concluded: "The novel flow diverter has showed great potential for direct treatment of cerebral aneurysms."
