Misonix Receives FDA Approval of Second Sonatherm(R) Soft Tissue Ablation System

FARMINGDALE, N.Y.--(HSMN NewsFeed)--Misonix, Inc. (NASDAQ: MSON ), a developer of minimally invasive ultrasonic medical device technology, which in Europe is used for the ablation of cancer and worldwide for other acute health conditions, has received 510(k) clearance from the U.S. Food and Drug Administration (“FDA”) to market its Sonatherm 600i High Intensity Focused Ultrasound (“HIFU”) Soft Tissue Ablation System in the United States, which will be used to ablate certain soft tissue lesions, excluding the prostate gland, in general surgery.

The Sonatherm 600i System is an evolution of the Company’s Sonatherm 600 System that received FDA clearance in January, 2006. The Sonatherm 600i System adds imagery and motion capability. To date, the two Sonatherm Systems are the only HIFU-based soft tissue ablation systems that have received FDA clearance for general surgery.

The Sonatherm 600i utilizes HIFU to ablate tissue intra-operatively or laparoscopically from a focal point back to the surface of the tissue of the lesion, eliminating the need to puncture or otherwise invade the tissue mass. This capability differentiates the Sonatherm from other conventional surgical devices; i.e. cryo or radio frequency, which generally requires the tissue mass, or organ, to be punctured with multiple needles or probes.

A series of clinical cases are being conducted under the guidance of noted HIFU expert, Dr. Michael A. Marberger, Chairman and Professor of the Department of Urology, Vienna, Austria. Dr. Marberger has published numerous clinical papers in support of this modality. According to Dr. Marberger, procedures to date were successfully competed with positive ablation effect noted in tumors within human kidneys. The Company expects to arrange for a number of leading physicians from the U.S. to observe the Sonatherm 600i in clinical practice at the University of Vienna hospital prior to performing surgical procedures in the U.S. Clinical data collection will take place at several sites in the U.S. prior to commercial sale of the product.

“The FDA approval represents another important milestone for our HIFU program in which we are working on treatment in several organs. We believe this technology addresses a large surgical marketplace and provides healthcare professionals, who are constantly looking for innovative therapies, important surgical and therapeutic benefits,” said Michael A. McManus, Jr., President and Chief Executive Officer of Misonix.
