Table 2.

Diameter, angle and offset location for the Original configuration and all surgical variations for the Y-graft baffles generated. The letters in italics correspond to those in Figure 2 (A.1 and A.2) and refer to specific parametric variations; n: original angle location; e: original offset location; 0.5D: offset distance of half a diameter from original value.
