Aims and objectives: Thiel-embalmed [1,2] human cadavers retain ‘life-like’ properties including colour, tissue quality and flexibility and vessel patency. Thiel cadaver models have been used successfully with B-mode ultrasound for clinical training [3] and device development [4]. Colour Doppler ultrasound is superior t[...]

Methods and materials: Stent development & testing 1.   A Thiel-embalmed human cadaver was prepared with perfusion to demonstrate the presence of Spiral Flow post stent deployment using Colour Doppler ultrasound. Access to the right common femoral artery was created by incision. Vascular access in the right[...]

Results: Stent development & testing 1.       Contrast enhanced Colour Doppler ultrasound was used to evaluate the efficacy of the device to induce spiral flow within the vessel. At a constant flow rate of 0.4L/min, the vessel was imaged at 1cm intervals distal to the stent posit[...]

Conclusion: Colour Doppler ultrasound was successful in visualising the presence of flow in the Thiel-embalmed cadaver model. It has been utilised in the development of stent grafts and fluoroscopic stent placement simulations with the ability to indicate the presence of normal or abnormal flow in the stent gra[...]
