Abstract

A needle device for penetrating body tissues while substantially reducing the risk of damage to blood vessels and body organs by using visual control of the operative tip during insertion and the procedure, is disclosed herein. The needle device of the present invention has a large and diverse applicability to a number of medical procedures by enabling internal visual inspection of body tissues and cavities during treatment without open surgery or supplemental penetrating or visualization devices.
