vasculature and ureter silicone model. Arch of aorta was represented
in the region 1 of the model; this region was used for speed control
experiments and preliminary experiments with the feedback system.
Sub-clavian arteries and a segment of common carotids near aorta
arch were represented by region 2 of the model; this region was
used for a two-dimensional path reconstruction experiment and
the speed control experiment. A ureter silicone membranous model
was used for a one-dimensional path reconstruction experiment. A
segment of a common carotid was represented by region 3 of the
model and was used for path reconstruction experiments. The ACIS
was evaluated inside two types of silicone arterial models, block
and membranous. Those silicone models were built using CT data
of human arteries and ureter, allowing a simulation of endovascular
or urological catheter insertion inside silicone models. The shape
