  • a tubular shaft with an expandable blade comprising one or more cuts in the tubular shaft, wherein the expandable blade is near a distal end of the tubular shaft, and wherein the expandable blade deploys substantially radially from the tubular shaft; and

    an actuator member that extends beyond the distal end of the tubular shaft and includes a bearing surface configured to press against the distal end of the tubular shaft when the actuator member is moved relative to the tubular shaft in a first direction to deploy the expandable blade;

    wherein the bearing surface is not connected to the tubular shaft such that substantially any tensile resistance exists between the tubular shaft and the actuator member when the actuator member is moved relative to the tubular shaft in a second direction that is substantially opposite from the first direction.
