3.1 Graft Oozing
The dimensions of the prostheses used for testing are summarised in
Table 1. Following full pressurisation of the prosthesis, blood oozing
was immediately noted. A blood stream (Figure 1) was noted 30 seconds
after peak pressure was reached. By 60 sec, a heavy stream of blood
oozing from the graft was noted (Figure 2). Oozing was also noted along
the graft branches. For each device, in total 250.0 mL of blood oozed
through the prosthesis wall within 60 seconds.
