Abstract: A deflective medical device including a catheter shaft having a distal end, and an ablation electrode disposed at the distal end of the catheter shaft. A deflection body is provided within the catheter shaft, and the deflection body includes a longitudinally extending spine. Multiple slots are formed in the deflection body, and the slots define a group of ribs. A flex member is disposed distal to the deflection body, and an intermediate region is defined between the deflection body and the flex member. A deflection mechanism is coupled to the intermediate region, which includes a retaining member, a collar, and a pull wire coupled to the collar.
