a biodegradable implant and a method for manufacturing one . the implant comprises a matrix component containing at least one biodegradable polymer or copolymer and a pyrrolidone plasticizer that is adapted to reduce the rigidity of the implant . the plasticizer substantially exits from the implant after coming into contact with tissue fluids of the organ system in such a manner that the bending resistance of the implant prior to the insertion of the implant into the organ system is lower than after its insertion into the organ system .
