Abstract
An expandable tissue dilator for dilating tissue around a spinal column includes a housing and a shaft at least partially positioned distally of the housing and adapted to pierce a tissue around the spinal column. An expandable member attached to the housing expands around a portion of the shaft to dilate the pierced tissue in a single-pass dilation resulting in a reduction of any traumatic impingement of nerves or muscle tissue and reduction in procedure time.
