Important Safety Information
MENTOR™ CONTOUR PROFILE™ Tissue Expanders are used for breast reconstruction following mastectomy, correction of an underdeveloped breast, scar revision and tissue defect procedures. The expander is intended for temporary subcutaneous or submuscular implantation and is not intended for use beyond six months. CONTOUR PROFILE™ Tissue Expanders include magnetic injection domes, which contain a rare earth permanent magnet, and are NOT MRI compatible. The device could be moved by the MRI causing pain or displacement, potentially resulting in a revision surgery. Do not use the CONTOUR PROFILE™ Tissue Expander in patients where an MRI may be needed. DO NOT use the CONTOUR PROFILE™ Tissue Expander in patients that have a previously implanted device such as pacemakers, drug infusion devices, artificial sensing devices, etc. that could be affected by a magnetic field. Mentor has not tested the in vivo effects of radiation therapy with CONTOUR PROFILE™ Expander devices and cannot warrant the safety of such use. The incidence of extrusion of the expander has been shown to increase when the expander has been placed in injured areas: scarred, heavily irradiated or burned tissue, crushed bone areas, where severe surgical reduction of the area has previously been performed and where steroids are used in the surgical pocket.
Your patient needs to be informed and understand the risks and benefits of MENTOR™ Tissue Expanders, and provided with an opportunity to consult with you prior to deciding on surgery.
For detailed indications, contraindications, warning and precautions associated with the use of all MENTOR™ Implantable Devices, please refer to the Instructions for Use (IFU) provided with each product, or review the Important Safety Information provided at mentorwwllc.com
