Claim:
1. A system for electrospinning a fiber matrix onto a tubular member to form a vascular graft device, the system comprising: at least one nozzle; a tubular member that is living tissue in a spaced relationship to the at least one nozzle, the tubular member defining an internal lumen; a rotatable first plug inserted at a first end of the tubular member; a rotatable second plug inserted at a second end of the tubular member; at least one force imposing mechanism connected to at least one of the first or second plugs; and a fluid source that pressurizes the lumen of the tubular member with a fluid; wherein an electrical potential is applied between the at least one nozzle and the tubular member and/or the fluid within the lumen of the tubular member, the electrical potential drawing at least one fiber from the at least one nozzle to the tubular member; and wherein the system does not comprise a mechanical type of mandrel inserted through the lumen of the tubular member.
