Title: Understanding the mechanism and effects of stent fracture – a combined experimental, finite element analysis and computational fluid dynamics study
Highly motivated students interested in pursuing a PhD in the Medical and Biological Engineering Research Group (MBE) within the School of Engineering at the University of Hull are invited to apply.
The Hull and East Yorkshire NHS Hospitals Trust undertakes between 2000 and 3000 angioplasty and coronary stent procedures per annum. Increasingly, stent fracture (SF) is an important cause of stent failure, associated with an increased risk of morbidity and potentially mortality following these percutaneous coronary interventions (PCI). All stent designs undergo fatigue testing by the manufacturer, but this is done with the stent positioned/deployed in a straight line, therefore not considering the increased stress related to angulation of stent deployment within bifurcations. Further work is therefore needed to evaluate the stents used in contemporary practice for their propensity to fracture in angulated vessels. The aims of the present study are to inform clinical practice by developing a computer model to evaluate the influence of vessel angulation on stent stress; evaluating the effect of fatigue loading on angled stents; modelling type 1 fractured stents to predict time to further fracture; and to evaluate the effect of SF on flow characteristics. This will be conducted using a combination of mechanical testing, finite element (FE) analysis and computational fluid dynamics (CFD).
Applicants should have at least a 2.1 honours degree (or predicted) in an appropriate Engineering discipline with specific experience in finite element analysis. Previous experience in experimental techniques, use of ANSYS finite element analysis software and CFD would be an advantage.
This full-time UK/EU PhD Scholarship will include fees at the ‘home/EU' student rate and maintenance (£14,013 in 2013/14, subject to final confirmation) for three years, depending on satisfactory progress.
PhD students at the University of Hull follow modules for research and transferable skills development and gain a Masters level Certificate, or Diploma, in Research Training, in addition to their research degree.
Applications should be made via the University’s online application system:
Closing date 21st June 2013. Interviews held on 2nd July 2013. Studentships will start in September 2013, successful applicants will be informed of the award by 5th July 2013.
