Who may be able to join

Subject is female and is at least 18 years old
A candidate for:
Primary breast reconstruction in women at least 18 years old with surgically absent breast tissue (two-stage reconstruction [tissue expanders utilized with or without the use of human acellular dermal matrices (ADM), limited to AlloDerm® and FlexHD® PLIABLE, utilized in a prior surgery to expand tissue for study device placement] to replace breast tissue post-mastectomy)
Revision surgery in women at least 18 years old with surgically absent breast tissue (previous reconstruction with silicone-filled or saline-filled implants or revision reconstruction requiring expansion surgery prior to surgery for study device implantation, with or without the use of human acellular dermal matrices (ADM), limited to AlloDerm® and FlexHD® PLIABLE, utilized in a prior surgery to expand tissue for study device placement)
Subject understands and signs the Informed Consent
Subject agrees to return device to Mentor if device is explanted
Subject agrees to comply with follow-up procedures, including returning for all follow-up visits
Physician determines implant volume appropriate for the patient taking into account the subject's BMI and chest width

Who cannot join

Subject is pregnant at time of enrollment
Subject is a current smoker, or has smoked within 3 months prior to enrollment, or plans to resume smoking within 3 months post-enrollment
Currently has uncontrolled diabetes (at time of screening or enrollment)

Currently has a condition that could compromise or complicate wound healing. Note, obesity alone is not an exclusion. All surgical risk factors (obesity, diabetes, smoking history, and prior radiation) should be considered in totality for proper subject selection

About this study

Official title: Post-Approval Study of the Safety and Effectiveness of the Mentor Smooth Larger Size MemoryGel Ultra High Profile (UHP-L) Breast Implants in Subjects Who Are Undergoing Primary Breast Reconstruction or Revision Reconstruction

The study will evaluate the long-term safety and effectiveness with the Mentor MemoryGel® Larger Size Ultra High Profile (UHP-L) Breast Implants.

Read the detailed description

Subjects, whose body shape is suited to a larger size implant than are currently available, will have their breasts reconstructed using the UHP-L Breast Implants either for the first time after a full mastectomy or as a revision of a previous breast reconstruction.

Conditions: Breast Reconstruction, Revision Breast Reconstruction
Being tested: Mentor Larger Size MemoryGel Ultra High Profile Breast Implant

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Mentor Larger Size MemoryGel Ultra High Profile Breast ImplantDevice
Also called UHP-L Breast Implant
The Mentor smooth larger size MemoryGel® Ultra High Profile (UHP-L) breast implants are large round silicone gel-filled breast implants. The devices are made with cross linked layers of silicone to provide the prosthesis with elasticity and integrity.
