vascular grafts are designed for peripheral vascular
disease and hemodialysis access. These vascular
grafts are an innovation in surface dynamics,

vascular grafts, when compared to a similar
graft without carbon, are associated with a
decrease in platelet adhesion and fibrin depositionbut
are not associated with any change in patency
or reduced embolism in animal studies.
- In preclinical animal studies:
carbon lining significantly decreases platelet

with standard PTFE grafts vs. carbon-lined
PTFE grafts show statistically greater thrombus-free
