2 Fig. 1 Preclotting efficiency vs. porosity. Measurements were taken of water porosity initially and after each of four preclotting steps.

3 Fig. 2 Flow surface of gross specimens after 56-day implantation shows typical study results for microporous, woven, double (internal and external) velour, and external velour prostheses. A, Gore-Tex (PTFE). B, DeBakey Woven (“Soft-Crimp”). C, Microvel. D, Bionit II.

4 Fig. 3 Scanning electron microscopy from midsections of (A) microporous Gore-Tex with no cell coverage; (B) DeBakey Woven, with endothelial cell coverage; (C) warpknit Bionit II, with endothelial cell coverage (see Fig. 6.). (All magnifications, × 1000.)

5 Fig. 4 Transmission electron microscopy from midsections of (A) Gore-Tex, with no cell coverage; (B) DeBakey Woven, with endothelial cell coverage; (C) Bionit II, with endothelial cell coverage (enlargement shows complex interdigitating cell junction). (All magnifications, × 6000.)

6 Fig. 5 Factor VIII/von Willebrand factor immunofluorescent staining from midsections of (A) Gore-Tex, with no granular immunofluorescent staining visible; (B) DeBakey Woven, clearly showing granular immunofluorescent staining, which is positive for endothelial cells; (C) Bionit II, clearly showing granular immunofluorescent staining which is positive for endothelial cells. (Light microscopy, × 200.)
