Vascular graft sealants.
Although the use of vascular graft sealants is primarily intended to decrease the porosity of grafts upon implantation, sealants also may serve to passivate polymeric surfaces or act as a temporary scaffold for cell attachment and subsequent graft healing.  The safety and efficacy of vascular grafts sealed with albumin, collagen, and gelatin have been established through many preclinical and clinical studies.  Such products have been used in clinical practice since the mid-1980s.  Any differences in the long-term human healing response to these sealants and the clinical relevance of such differences can be assessed only as the time of implantation increases and the data are evaluated.
