<p>A method of interventional surgery is described. The method may include inserting an actuator (12) within a body of a vascularized organism and positioning the actuator (12) adjacent a target region within a vessel of the body. The actuator (12) is operated to cause a needle (14) thereof to move in a substantially perpendicular direction relative to a wall of the vessel to produce an opening therein. A therapeutic or diagnostic agent may be delivered by the needle (14) to the target region via the opening in the vessel.</p> |
