A deflectable catheter includes a catheter body (12), an intermediate section (14), a tip electrode (29) and a control handle (16) for deflecting the catheter by manipulation of a puller element (31) that is made of a high modulus fiber material and extends through the catheter body and the intermediate section. The proximal end of the puller element is housed in the control handle and the distal end of the puller element is in a wrapped configuration and engages with a distal tip member or the intermediate section.
