Patent ID: 8206344

Claim:
A method comprising: forming a catheter shaft having a proximal end and a deflectable distal end, the catheter shaft including a delivery lumen extending from the proximal end to the deflectable distal end thereof; forming an actuator lumen completely sealed off from the delivery lumen, wherein a first portion of the actuator lumen extends within the catheter shaft from near the deflectable distal end to an intermediate portion of the catheter shaft; coupling an actuator lumen liner to and in communication with the first portion of the actuator lumen to thereby form a second portion of the actuator lumen at a sidewall exit lumen in the intermediate portion of the catheter shaft, wherein the actuator lumen liner forming the second portion of the actuator lumen extends outside of the catheter shaft; receiving a pull wire within the actuator lumen; and anchoring a pull wire distal end with the deflectable distal end of the catheter shaft.
