摘要：
An apparatus for performing a nerve block procedure, the apparatus being composed of an echogenic needle or an echogenic soft tissue tunneling device and an echogenic catheter configured for controlled delivery of a medication. The apparatus may further include a sheath such that at least one of the needle or tunneling device and sheath is echogenic. The present invention also encompasses a system for performing a nerve block procedure, the system includes introducing an echogenic needle in the general area of a nerve bundle, positioning the echogenic needle adjacent the nerve bundle utilizing sonic imaging techniques, introducing an echogenic catheter configured for controlled delivery of a fluid through the echogenic needle, withdrawing the echogenic needle, positioning the echogenic catheter adjacent the nerve bundle utilizing sonic imaging techniques, and delivering fluid to the nerve bundle through the echogenic catheter.
