Abstract: A system for electrospinning a fiber matrix on a tubular member includes at least one nozzle, a tubular member in a spaced relationship to the at least one nozzle, and a fluid source for pressurizing a lumen of the tubular member. An electrical potential is applied between the at least one nozzle and either the tubular member or fluid from the fluid source. The electrical potential draws at least one fiber from the at least one nozzle to the tubular member.

Abstract: A cartridge device is provided for applying a fiber matrix to a tubular member such as a saphenous vein graft. The cartridge includes a housing, a tubular member holder, a rotational drive, and a polymer delivery assembly. The housing defines a chamber which surrounds the tubular member holder. The rotational drive rotates the tubular member during the fiber application process.
