- Fig 1.
Virtual cerebrovascular models show ICA siphons with mild (A), medium (B), and severe (C) curvature.
- Fig 2.
The virtual core-shell structure (A) is designed for the preparation of the physical ABS model (B), which contains the CoW (C) as the core. After the silicone is cured, the ABS model (B) is dissolved in xylene, resulting in a transparent CoW silicone replica (D). E, With the same manufacturing process, a representative right ICA siphon is built from patient 18.

The S-S curves of Sylgard 184, LIM 6030, and a human MCA from postmortem examination are compared. At low stretch, the elastic property of LIM 6030 is close to that of the MCA from postmortem examination. Short solid line indicates the MCA from a postmortem examination; dark dashed line, LIM 0.49 mm in thickness; light dashed line, LIM 0.52 mm in thickness; dotted line, LIM 0.53 mm in thickness; diamond, Sylgard 0.49 mm in thickness; square, Sylgard 0.53 mm in thickness; triangle, 0.61 mm in thickness.
