The Saf-T-Coil 33 with a long beaded-plastic tail was first commercially sold Saf-T-Coil IUD. It was manufactured in March, 1965 by Cebesco, a subsidiary of Deseret Pharmaceutical. The 33-S model was also marketed in 1965. The long beaded tail was removed, and the "S" stands for the suture tail, replacing the beaded-plastic tail of the original 33 model. Barium sulfate was added to the ethylene vinyl acetate copolymer for radiopacity. The stem tapers at the cervical end with a rounded eyelet through which the two blue nylon cervical threads are attached. One arm of the device ends in a bulbed tip.
