Claim 0:
1. An apparatus for performing a medical procedure, comprising:
a shaft configured for insertion through a sheath into a cavity of an organ of a patient; and
a folding fan catheter fixed to a distal end of the shaft, the folding fan catheter comprising:
a resilient foldable frame comprising a plurality of splines, the resilient foldable frame fixed to the distal end of the shaft and configured to be unfolded so as to assume a fan shape, each spline of the plurality of splines being generally flat and comprising a proximal planar portion, a distal planar portion, and a twisted portion disposed therebetween;
a puller wire attached to a distal end of at least one spline and configured to, when pulled in a proximal direction, cause the plurality of splines to bend at the twisted portion and to cause the resilient foldable frame to unfold to the fan shape;
one or more flexible surfaces, coupled to the resilient foldable frame to form a fan-shaped surface when the resilient foldable frame is unfolded; and

a plurality of electrodes disposed over the one or more flexible surfaces configured to contact tissue to perform the medical procedure.
