Figure 1. Ligation valve. Style 1400 Heyer-Schulte Tabari saline-filled implant (placed 1972) with a ligation valve seen here pulled out of the pocket in which it can be buried (photographed upside down). A narrow strip of Dacron mesh-reinforced elastomer is present around the entire circumference of the implant inside the implant shell. Two crescent-shaped strips (arrows) of Dacron felt fixation material are present on the posterior superior part of the implant, with some ingrown tissue still attached (143,144).
