Patent ID: 8257344

Claim:
A deflectable catheter comprising: a catheter body having an outer wall, proximal and distal ends, and at least one lumen extending therethrough; a tip section comprising a flexible tubing having proximal and distal ends and at least two lumens extending therethrough, the proximal end of the tip section being fixedly attached to the distal end of the catheter body, a control handle mounted at the proximal end of the catheter body, the control handle comprising: a piston receiving assembly comprising a proximal barrel and a distal barrel, the distal barrel comprising a piston chamber at its distal end, and a piston longitudinally slidable within the piston chamber along a longitudinal axis of the control handle, wherein the distal barrel of the piston receiving assembly engages a proximal end of the piston to substantially prevent rotation of the piston relative to the piston receiving assembly; and means for deflecting the tip section by manipulation of the control handle.
