The present invention refers to a surgical device, characterized in that it comprises a copolymer of the formula: where Ar is 1,3- or 1,4 phenylene, n-has an average value of 4 to 10, a and b are numbers such that the repeating units, represented by b, are from 1 to 50 weight percent of the copolymer, yy is a number whose average value reflects the degree of polymerization resulting in a solid polymer having an inherent viscosity of at least 0.3 dl / g , measured at 25 degrees C, at a concentration of 0.1 g / dl in hexafluoroisopropyl alcohol. |
