1. An instrument accessory device, comprising:
a body having a proximal end, a distal end, a longitudinal axis, and a wall defining an instrument lumen extending between the proximal end and the distal end along the longitudinal axis of the body, the instrument lumen having an inlet and an outlet at the respective proximal end and distal end of the body, the instrument lumen configured to slidingly receive a length of an instrument extendible through the instrument lumen;
an expandable member disposed about the wall at the distal end of the body, the expandable member extending between a proximal end and a distal end along a longitudinal axis of the expandable member;
an elongate delivery member having a proximal end and a distal end that is attached to the body, the body positioned at the distal end of the elongate delivery member, the elongate delivery member comprising an inflation lumen extending between the proximal end of the elongate delivery member and the distal end of the elongate delivery member and in fluid communication with the expandable member at the distal end of the elongate delivery member;
a handle at the proximal end of the elongate delivery member, wherein the inflation lumen is continuous with a handle lumen extending along the handle; and
a stylet removably receivable within the inflation lumen, the stylet having a cap at a proximal end of the stylet, the cap reversibly coupleable to the handle;
wherein the elongate delivery member is configured to slide the instrument lumen of the body and the expandable member along the length of the instrument when extended therethrough.
