[Biostability of plastic endotheses].
These is shown in this paper the literature review and author's studies on the in vitro and in vivo ageing changes in plastic endotheses under certain conditions. The changes occurring in endotheses exposed to no major mechanical loads were considered in particular. Polyamides, polyethylene derivatives, polyesters, polyurethanes and silicone rubbers were found to belong to the polymers unstable under biological conditions.olyesters, polyurethanes and silicone rubbers were found to belong to the polymers unstable under biological conditions.
