a tubular prosthetic article having at least four chemically distinct fibers is disclosed . a first and second fiber are made of absorbable polymers and a third and fourth fiber are made from nonabsorbable polymers . the absorbable polymers are made from the monomeric units of esters such as glycolic acid , lactic acid , polydioxanone and blends of the same . the nonabsorbable polymers may be made from esters such as polyethylene terephthalate , polybutylene terephthalate , polybutester , or blends of the same . these four chemically distinct fibers may be woven or knitted into a tubular form .
