BSD Medical (Salt Lake City), a maker of microwave systems used primarily in the treatment of cancer, reported FDA clearance for its MicroThermX-100 Microwave Ablation System (MTX-100).

The MTX-100 is a small, mobile system that includes a computer, a microwave generator, single-patient-use disposable applicators and a proprietary thermistor-based temperature monitoring system. The delivery of microwave energy is controlled by time and power parameters set by the operator using an interactive touch-screen monitor that allows the operator to control the treatment.

The MTX-100 provides minimally invasive access to the target tissue and can be used in open surgical as well as in percutaneous ablation procedures, enabling it to be used by both surgeons and interventional radiologists. It is indicated for use in ablation of soft tissues. BSD said that by using microwaves in treatments the MTX-100 competes head-on with radio frequency ablation technologies that require patient grounding pads.

BSD says it designed the MTX-100 to use up to four treatment applicators simultaneously, working together through the company's phased array technology to provide larger and more uniform zones of ablation during a single procedure.
