An overview of the requirements of a TEBV

I) the mechanical properties of the vessel must be sufficient to withstand the pressure caused by flow for extended periods of time without resulting in an aneurysm or bursting;

II) the vessel should be sufficiently compliant to avoid a compliance mismatch, a known factor for graft failure [19];

III) the surgical suitability must be considered; the graft must have sufficient suture retention strength, and be easy to handle by the surgeon;

IV ) the vessel must be compatible with the host, i.e. not elicit an inflammatory reaction, be non-toxic, and non-carcinogenic;

V) the vessel should be capable of remodeling to meet the demands of the vasculature;

VI) the surface of the graft should not be prone to thrombus formation.

VII) be produced in a large scale, cost effective manner, and available in various dimensions;

VIII) show acceptable variation between batches.
