His vocation as an Ob/Gyn provided the motive; his experience as navigator in Israeli Air Force provided the means. Yoav Paltieli, MD, founded UltraGuide Inc. in 1996 to develop image guidance systems for use in minimally invasive interventional and surgical procedures. Based on cockpit guidance systems, UltraGuide's technology uses sensors and transmitters to display the position of an interventional instrument—tumor ablation probe, biopsy needle or drug delivery device—over preoperatively acquired computed tomography (CT) or real-time ultrasound images. The systems provide a graphic overlay of the interventional device's position and plot its future trajectory before it touches the patient's body. That overlay is provided both within the plane of the image or out of plane (across multiple slices in the case of CT, or from an angle perpendicular to the ultrasound beam). This capability enables physicians to plan the least invasive approach to the site of interest and maneuver around organs that might lie in the instrument's path.
"Ours is an enabling technology," says UltraGuide's president and CEO John Hesemann, "providing guidance for interventional and minimally invasive procedures...
