Abstract
A medical device is provided for use in a nerve block procedure to dispense a numbing agent into a fascial plane of a patient's body that obviates the need for injecting a test dose to. The medical device can include a needle having a wire control mechanism and an echogenic feeler wire that can be viewed using an ultrasound probe. When the needle tip is positioned inside of the patient's body and the user controls the wire control mechanism to cause the feeler wire to move from the non-deployed state to the deployed state, a distal portion of the feeler wire extends out of the needle tip into the patient's body and moves within a region of the patient's body. Viewing the feeler wire on an ultrasound enables one to ascertain whether the needle tip is properly located in the fascial plane without having to inject a test dose.
