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.
