| 1. A mapping catheter comprising:
an elongated tubular catheter body having an outer wall, proximal and distal ends, and at least one lumen extending therethrough;
an intermediate section having proximal and distal ends and at least one lumen extending therethrough, the proximal end of
the intermediate section being attached to the distal end of the catheter body; and
a mapping assembly comprising:
a tubular structure having a generally straight proximal region attached to the intermediate section, a generally circular
main region generally transverse and distal to the proximal region having an outer circumference, a transition region connecting
the proximal region and the main region, and a generally straight distal region distal the main region and extending substantially
tangentially from the main region, wherein the tubular structure comprises a non-conductive cover over at least the main region
of the mapping assembly,
a support member having shape-memory disposed within at least the main region of the mapping assembly; and
a plurality of spaced-apart electrodes carried by the generally circular main region of the mapping assembly.
