ABSTRACT:
An insertion device with an insertion axis includes an axial actuator with a first portion and a second portion. The first portion is moveable along the insertion axis relative to the second portion. The insertion device further includes a first tube coupled to the first portion of the axial actuator, and the first tube is movable along the insertion axis in response to movement of the first portion relative to the second portion. The device further includes a second tube having a radially biased distal end. The distal end is substantially contained within the first tube in a first state, and the second tube is rotatable with respect to the first tube. Also, the second tube is axially movable to a second state, and a portion of a distal end of the second tube is exposed from a distal end of the first tube in the second state.
