ABSTRACT:
A medical system is disclosed that includes a cannula, an introducer stylet removably disposed within the cannula and a target confirmation device selectively insertable within the cannula. In an embodiment of the invention, the introducer stylet is configured for insertion into a patient's body. The outer cannula is sized to fit over the introducer stylet and is positionable at least partially within the patient's body after insertion and removal of the introducer stylet. The target confirmation device is insertable into the outer cannula after removal of the introducer stylet and is configured to confirm the position of the outer cannula relative to the target site. A medical procedure using the medical system of the present invention is also disclosed.
