NeoDynamics AB presents a new technology for achieving large histologic samples when performing biopsies that, regardless of needle size and properties of the lesion, makes it possible to precisely place an Ultrasound guided needle in the area from which the diagnostic tissue is to be taken. Our unique driver substitutes the commonly used spring-loaded mechanisms. It enables the physician to precisely and seamlessly maneuver even large diameter needles into the tumor. This is achieved by the physician applying short mechanical energy pulses.
