• a guide member and a displacement member supported by the guide member, the guide member configured to operably couple with the transrectal probe and comprising a distal end, a proximal end opposite the distal end, and a length extending along a longitudinal axis between the distal and proximal ends, the displacement member configured to support the access needle and displace the access needle along at least a portion of the length of the guide member between the distal and proximal ends, the access needle configured to extend into the subcutaneous tissue when the access needle is displaced to the distal end.
