The objective of our research was to use 3-D FLUENT simulation
modelling to optimise the design of our new clot retrieval device
(called the ‘GP’ MTD) and to then use this design in experiments to
demonstrate the efficacy of our MTD based on a combination of the
results of theoretical modelling and experimental laboratory
investigation. A range of prototype ‘GP’ MTD’s of various internal
diameters mounted on the end of an arterial catheter tube and embedded
within the arterial catheter tube, were use to remove jelly-like
artificial clots in a plastic tube (representing an artery). Overall,
the most effective device was found to be the prototype device that was
embedded within the arterial catheter tube, which had an internal
diameter of 2mm with a spiral helix. The results also show the value of
theoretical modelling in optimising the design of this device.
