Claim:
1. A medical apparatus for administering a continuous flow or intermittent bolus of an anesthetic agent to facilitate a continuous or a prolonged nerve block to one or more nerves, comprising: a catheter comprising a hub, a proximal end, a distal end, at least one lumen extending from the proximal end to the distal end, a first lateral port arranged at a location proximal to the distal end of the catheter and arranged at a first angular location relative to a longitudinal axis of the catheter, a second lateral port arranged at a location proximal to the first lateral port and arranged at a second angular location relative to a longitudinal axis of the catheter, and a third lateral port arranged at a location proximal to the second lateral port and arranged at a third angular location relative to a longitudinal axis of the catheter, wherein the first angular location is different than the second angular location, the second angular location is different than the third angular location; and a cannula comprising a hub, a proximal end, a distal end and a lumen extending from the proximal end of the cannula to the distal end of the cannula, the cannula configured to be arranged in the at least one lumen of the catheter such that a distal end portion of the cannula extends past the distal end of the catheter, wherein a region near a distal end of the cannula comprises one or more imaging markers configured for external imaging and the cannula is configured to receive an electrical signal to provide nerve stimulation to the one or more nerves, wherein the catheter comprises a material configured to substantially prevent kinking and a plurality of markings, wherein the catheter and the cannula are configured to be inserted into a patient substantially simultaneously, and wherein the catheter is configured to remain in the patient when the cannula is removed from the catheter and the catheter is configured to receive the continuous flow or intermittent bolus of an anesthetic agent.
