Claim Text:
1. A catheter comprising: an elongated catheter body generally defining a catheter axis; a distal electrode assembly mounted on a distal end of the catheter body, the distal electrode assembly having a first elongated member defining a longitudinal axis and a plurality of spines surrounding the first elongated member and converging at their proximal and distal ends, each spine comprising at least one electrode and having a curvature so that the spine bows radially outwardly from the first elongated member; a proximal electrode assembly mounted on the distal end of the catheter body proximal of the distal electrode assembly and having a second elongated member configured with a generally radial portion and a generally circular portion generally transverse to the catheter axis, the generally circular portion comprising a plurality of electrodes; an intermediate section between the catheter body and the proximal electrode assembly, the plurality of spines of the distal electrode assembly being fixedly mounted at their proximal ends to the intermediate section; a control handle at a proximal end of the catheter body; a first tensile member extending between the control handle and the distal electrode assembly; and a second tensile member extending through the catheter body and into the intermediate section, wherein the control handle is configured for user manipulation of the first tensile member to change the curvature of the spines and for user manipulation of the second tensile member to deflect the intermediate section.
