ABSTRACT:
Prostheses with improved chemical and mechanical properties manufactured that includes a radiation resistant and hydrolytically stable biocompatible fabric having outer and first and second ends with a textile fabric that includes a naphthalene dicarboxylate derivative polymer having the general formula:wherein R1and R3are the same or different groups and are independently selected from the naphthalene dicarboxylate derivative repeating unit (I), a hydrogen radical and a methyl radical. R2is an alkylene radical having 1 to 6 carbon atoms; n is from 10 to 200. Also contemplated are implantable prostheses that are flat constructions useful as patches and filters or tubular constructions useful as vascular grafts. A further aspect of this invention provides a method for making a radiation and thermal resistant and hydrolytically stable, steam sterilizable biocompatible prosthesis.
