The MarginProbe System

The MarginProbe System consists of two highly-engineered components — the Probe and the Console — designed to provide both reliable performance and ease of use for surgeons within the operating room environment. The system utilizes RF Spectroscopy in a unique and sophisticated way to analyze tissue to identify both normal and malignant cells.


The Probe is a lightweight, sterile, disposable device which the surgeon uses to control contact with the excised tissue. It connects to the Console for both electrical power and to enable the unit to establish a vacuum connection with the tissue specimen.  This provides consistency in the amount of pressure applied to the tissue for optimal measurements.

The Fringe Field Sensor is an integrated element of the probe, located at the tip of the instrument. It functions as the heart of the MarginProbe System. On contact with tissue, the sensor delivers an electrical field, then captures the electromagnetic response (reflection) of the examined tissue to distinguish tissue type (normal or malignant).  The low-power levels of both the instrument and the RF signals directed to the tissue assure that later examinations by the pathologist will be unaffected.

The Console incorporates a distinct module which enables the Margin Probe System to generate and collect RF signals used for margin analysis.  Other modules within the unit provide electric and vacuum control, data processing and information display.   A proprietary algorithm housed within the Console analyzes the bioelectric signatures from the tumor, and then compares those signatures to thousands of others in the MarginProbe database.
