1. A medical device comprising:
a handle including an actuator; and
a shaft including:
a body that defines at least one channel extending longitudinally through the shaft, wherein the at least one channel includes a guide wire channel extending from a proximal opening to a distal opening; and
a sleeve disposed around the body, the sleeve having (i) a discontinuity or (ii) a thinned portion at a position longitudinally between the proximal opening and the distal opening of the guide wire channel, wherein the discontinuity or thinned portion allows radial access from a position radially outward of the shaft to the guide wire channel to allow a guide wire to radially exit the guide wire channel at the position;
wherein the actuator is coupled to the shaft via at least one steering wire extending through a respective steering wire channel of the body,
wherein the handle is configured to receive user input and transmit the user input to a distal end of the shaft, and
wherein a distal end of the discontinuity or the thinned portion of the sleeve is proximal of the distal opening of the guide wire channel.
