(PIP=Poly Implant Prosthesis) Saline Breast Implants are simply silicone elastomer shell breast implants pre-filled with saline. The touted advantages of this breast implant is two-fold. The first is that the implant shell is thinner and, has a more natural feel, like that of silicone implants. The second is that no filling is required at the time of surgery minimizing the risk of contamination, and cutting down operative time. Bot points are moot since the PIP Saline Breast Implants are not available in the US, secondary to a lack of submitted safety data.
