MENTOR® CPX™4 Breast Tissue Expander

Used in breast reconstruction surgery, MENTOR® CPX™4 Breast Tissue Expander is designed to expand primarily in the lower portion of the breast, so the resulting pocket will accommodate the implant and slope like a natural looking breast.1 It also has an integral “injection dome” that allows surgeons to add saline solution to the expander and gradually stretch the breast tissue over several months.2
