Study of the Mentor Becker Expander/Breast Implant in Subjects Who Are Undergoing Primary Breast Reconstruction

Breast Reconstruction

Primary Breast Reconstruction

The purpose of this study is to determine the safety and effectiveness of the Becker Expander/Breast Implant in women who are undergoing primary breast reconstruction. Safety information on the rate of complications, such as infection will be collected, and used to help determine device safety. These implants are investigational devices. Approximately 300 patients at centers across the United States will be enrolled in this research study, by up to 30 sites. These patients will be implanted with Becker Expander/Breast Implant 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.

Silicone gel-filled breast implants were introduced in the early sixties and were in wide-scale distribution by the time the Medical Device Amendments to the Food Drug and Cosmetic Act was passed in 1976. In 1983, gel-filled breast implants were designated as Class III devices requiring premarket approval. In May 1990, the Food and Drug Administration (FDA) published a proposed request (515(b)) for Pre-market Approval Applications (PMA) and in April 1991 published the final request. This final publication put manufacturers of gel-filled breast implants on notice that for continued marketing of gel-filled breast implants, a PMA was due to FDA in 90 days from the final publication date. A pre-market approval (PMA) for the Mentor gel-filled breast implants was filed with the FDA in July 1991. At the FDA General and Plastic Surgery Advisory Committee meeting in November 1991, the committee recommended the submission of additional information to establish the safety and effectiveness of gel-filled breast implants. In January 1992, the FDA Commissioner announced a voluntary moratorium of the sale of gel-filled breast implants to allow the advisory panel time to assess additional information. In April 1992, the moratorium was lifted but only for reconstruction and revision subjects. Every subject implanted had to be part of an adjunct study, in addition to being offered participation in a registry of gel-filled breast implant subjects. In order to be implanted with gel-filled implants for augmentation, women had to be enrolled in an IDE clinical trial. A PMA for Mentor's MemoryGel™ Silicone Gel-Filled breast implants (which did not include the Becker Expander/Breast Implants) was subsequently filed with FDA in December 2003, and approved in November 2006 (P030053). As a condition of approval of P030053, new enrollment in Mentor's Adjunct Study has ceased, and women no longer have access to the Becker Expander/Breast Implants. This study is designed to evaluate the safety and effectiveness of Mentor's Becker Expander/Breast Implants for primary breast reconstruction
