Continuous anesthesia nerve conduction apparatus, system and method thereof

Abstract

The invention generally relates to a continuous anesthesia nerve conduction apparatus and method thereof, and more particularly to a method and system for use in administering a continuous flow or intermittent bolus of anesthetic agent to facilitate a continuous or prolonged nerve block. In one embodiment, the apparatus includes a sheath having a proximal end, a distal end and at least one lumen extending from the proximal end to the distal end. The sheath also includes an embedded conductive element for transmitting an electrical signal from a proximal portion of the sheath to a distal portion of the sheath. A cannula is arranged in the at least one lumen of the sheath and has a distal end protruding from a distal portion of the sheath. The cannula is electrically coupled to at least a portion of the embedded conductive element and is configured to provide nerve stimulation.

1 . A medical apparatus, comprising:
 a sheath having a proximal end, a distal end, a lateral port, and at least one lumen extending from the proximal end to the distal end; and   a cannula arranged in the at least one lumen.
