Prosthetic tubular article made with four chemically distinct fibers
摘要:
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.
