Mentor Introduces New Tissue Expander With Smooth Surface for Patients Undergoing Breast Reconstruction


The Company Receives 510(k) Clearance for CPX4 Smooth Breast Tissue Expander


CHICAGO, IL SEPTEMBER 26 -- Johnson & Johnson Medical Devices Companies* today announced that MENTOR Worldwide LLC, a global leader in breast aesthetics, has introduced a tissue expander with a smooth surface to its line of CPX4 Breast Tissue Expanders in the United States. The product will be on show at the 2018 American Society of Plastic Surgeons (ASPS) annual meeting taking place in Chicago from Friday, September 28, 2018 onwards.

Tissue expanders are used for breast reconstruction after mastectomy to expand the breast pocket to accommodate a breast implant. The new CPX4 device has a smooth surface designed to help ease insertion and removal1, and now includes additional suture tabs2 to enhance fixation while reducing the risk of rotation for subcutaneous and submuscular breast reconstruction.

“I am looking forward to using the CPX4 Smooth expander in prepectoral and submuscular breast reconstruction,” said Mark Migliori, MD,** a board certified plastic surgeon in Edina, Minnesota. “I believe it will offer ease of use during placement and removal with the added protection of the proprietary BufferZone, along with providing a natural breast shape and a soft comfortable expander for the patient.”

About 1 in 8 women in the United States will develop invasive breast cancer over the course of their lifetime. In 2018, this means an estimated 266,120 new cases of invasive breast cancer are expected to be diagnosed.3

ATHENA Clinical Trial Update

MENTOR also has plans to expand its portfolio of breast implants to broaden access for women who currently have few sizing options. In 2015, the company received U.S. Food and Drug Administration (FDA) Investigational Device Exemption (IDE) approval for its ATHENA4 clinical trial, which is evaluating the safety and effectiveness of larger sizes of MENTOR MemoryGel® Breast Implants for breast reconstruction patients with larger chest widths, larger breast sizes, higher BMI or greater amounts of removed mastectomy tissue.

The ATHENA study is the largest pre-approval, manufacturer-sponsored breast implant clinical trial registered with the FDA to date, in terms of number of reconstruction patients enrolled. As of September 2018, more than 330 women across 32 investigational sites have been enrolled. MENTOR anticipates completing enrollment of the full 400 patients by the end of 2018.
