Abstract
A handheld guidance device for use in conjunction with a C.T. scanner allows a user to accurately place a catheter within a patient's body. The guidance device includes a generally planar base including a bubble level to aid in maintaining the base horizontal. A needle support arm is pivotally secured to the base adjacent one end thereof, and a cooperating protractor indicates the relative angular relationship between the needle support arm and the base. Needle guides are provided on the support arm for slidingly supporting the catheter at a desired angle as the catheter is inserted into the patient's body. Graduations are marked on the needle support arm for indicating the depth of insertion. A reference line formed upon the base is adapted to be aligned with a transverse light beam projected by the C.T. scanner.
