1. A percutaneous telescopic tissue dilation system, comprising:

  • a first dilation tube having a proximal end and a distal end;

    a second dilation tube having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, the lumen being dimensioned to accommodate at least a portion of the first dilation tube; and

    a dilation tube retention assembly effective in retaining the second dilation tube in a substantially fixed position relative to the first dilation tube prior to dilation of tissue of an individual, and in releasing the second dilation tube from the substantially fixed position to facilitate movement of the second dilation tube towards the distal end of the first dilation tube to dilate tissue of a patient.
