Sientra, Inc. announced that the Food and Drug Administration (FDA) has granted a 510k-clearance for the Company's novel, patented1 AlloX2 Pro Tissue Expander. Building upon the proprietary dual port technology of the Company's ground-breaking AlloX2® tissue expander, the AlloX2 Pro expands this platform by removing 95% of the metal traditionally associated with tissue expander ports. This innovation allows the AlloX2 Pro to be labeled as MRI-conditional, making it the only tissue expander cleared in the United States for exposure to magnetic resonance imaging, an important screening tool for breast reconstruction patients.

Other innovative features of the AlloX2 Pro include minimal interference with radiation therapy for post-mastectomy patients,2 faster port filling and drainage, and a softer drain for enhanced patient comfort.
