1. A sequential dilation system for accessing a spinal target site, comprising:

  • an initial dilator including a cannulated body having a longitudinal axis, a tapered distal end, a proximal end, a length such that said proximal end extends beyond a skin surface when said distal end is positioned adjacent to said spinal target site, the initial dilator also including an integrated needle having a distal end configured for penetration into the spinal target site, the integrated needle being spring biased to a first position in which the distal end is contained within the cannulated body and deployable to a second position in which the distal end extends from the tapered distal end of the cannulated body; and

    at least one additional dilator slidable to the spinal target site over the initial dilator.
