Abstract
A device for accessing the spinal canal of a patient includes an introducer and a protective sleeve that is attached at one end thereof to a proximal end of the introducer. The protective sleeve has an outer stationary portion and an inner moveable portion. The outer and inner portions of the protective sleeve are separated by a crown region. A catheter is disposed inside the protective sleeve. During operation, the protective sleeve is advanced within the spinal canal to form a protective barrier between the catheter and the spinal cord. The catheter is advanced and retracted within the protective sleeve.
