A catheter adapted for rnapping andlor ablation in the atria has a basket-shaped electrode 5 array with two or more location sensors with a deflectable expander. The catheter has comprises a catheter body, a basket electrode assembly at a distal end of the catheter body, and a co:itrol handle at a proximal end of the catheter body. The basket electrode assembly has a plurality of electrodecarrying spines and at1 expander that is adapted for longitudinal movement relative to the catheter body for expanding and collapsing the assembly via a proximal end portion extending past the 10 control handle that can be pushed or pulled by a user. The expander is also adapted for deflection in responsive to an actuator on the control handle that allows a user to control at least one puller wire extending through the catheter body and the expander. |
