Core Gel Study of the Safety and Effectiveness of Mentor Round Low Bleed Silicone Gel-filled Mammary Prostheses

The Core Gel Study is designed to demonstrate safety and effectiveness of Mentor's Round Low-Bleed Silicone Gel-filled Mammary Prostheses in women who are undergoing primary augmentation, primary reconstruction, or revision. Safety information on the rate of capsular contracture, rupture, and infection will be collected, and used to help determine device safety. Approximately 1000 patients at centers across the United States will be enrolled in this research study. These patients will be implanted with silicone breast prostheses and monitored for 10 years to collect information on risks associated with the implant surgery as well as changes in the way these patients feel about themselves.
