Thrombosis and infection represent the two largest limiting factors determi
ning the long term success of implanted biomaterials. Infections associated
with biomaterials are difficult to treat, and appear to evade the host def
ense systems. Mechanisms relating infection to thrombosis are described. In
vestigations into the role of receptors in mediating adhesion to thrombi ar
e also discussed, in addition to strategies to reduce bacterial adhesion to
biomaterial surfaces.
