A METHOD OF INTERVENTIONAL SURGERY

摘要

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.
