Models of human blood vessels have many potential applications as aids in continuing research on new medical devices. The work detailed herein describes the development of a hydrogel material to mimic the mechanical and biological response of a range of human arteries. The developed hydrogels were characterized via swelling studies, differential calorimetry and spectroscopic techniques, while viscoelastic property measurement was investigated primarily using rheological testing methods. A range HEMA/NVP hydrogel materials were successfully developed with properties comparable to a range of arteries, namely, the thoracic and abdominal aorta with storage moduli (G′) varying from 43kPa to 64kPa depending on the formulation. This paper also describes the construction of a mathematical model for the viscoelastic properties of these materials, representing the time-dependent behaviour of the simulated areterial material when subjected to loading and unloading phenomena.
