Abstract
A system for administering regional anesthesia to a patient contains a regional anesthesia catheter and a partially splittable needle. The catheter has a first length and a second length, the first length having a first inner diameter, a first outer diameter, and a wall thickness, the second length having a first inner diameter, a first outer diameter, and a wall thickness, the diameters and the wall thickness of the second length being less than those of the first length. The needle is an atraumatic needle splittable along its length but remains hinged together by the needle tip itself. The system is particularly adapted for epidural and spinal catheterization with a medicament.
