1. A medical device, comprising:
- a catheter shaft defining a longitudinal axis;
a first carrier assembly coupled to the catheter shaft and having a first array of electrodes coupled to a plurality of first carrier arms; and
a second carrier assembly coupled to the catheter shaft and having a second array of electrodes coupled to a plurality of second carrier arms;
the first carrier assembly and the second carrier assembly each being independently movable between a configuration substantially parallel to the longitudinal axis, and a radially expanded configuration.

Abstract
Devices, systems and methods are disclosed for the mapping of electrical signals and the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be transformed from a compact, linear configuration to a helical configuration, such as to map and ablate pulmonary vein ostia.
