Abstract
A variety of devices for use in accessing the subarachnoid space are described. In several embodiments an introducer sheath is disclosed having three main sections, a distal portion, an intermediate portion, and a proximal portion. The distal portion and intermediate portion form a first bend, and the intermediate portion and the proximal portion form a second bend, giving the overall device a general L-shape, S-shape, C-shape, or a three dimensional Z-shape. Apparatuses for attaching an introducer sheath to the skin of a patient are also discussed, as are methods for using, shaping and sizing an introducer sheath.
