Claim:
1. A system for performing mapping and ablation, the system comprising: a power generator; an ablation device including a handle, an ablation element, and an elongate body defining a distal portion, a proximal portion coupled to the handle, and a longitudinal axis, the ablation element being located on the distal portion of the elongate body and coupled directly to the power generator; a resilient mapping sleeve disposable about at least the ablation element of the distal portion of the ablation device, the mapping sleeve defining a distal portion, a proximal portion, an inner surface, an outer surface, and a primary lumen having a longitudinal axis; a plurality of mapping electrodes disposed on the outer surface of the mapping sleeve, each of the plurality of mapping electrodes including an electrode wire that is coupled directly to the power generator; and a tubular retraction element coupled to the proximal portion of the mapping sleeve and defining a lumen and a longitudinal axis, at least a portion of the electrode wire of each of the plurality of mapping electrodes being located within the lumen of the retraction element, the longitudinal axis of the retraction element being offset from the longitudinal axis of the mapping sleeve, exerting a pull force on the retraction element toward the proximal portion of the elongate body pulling the mapping sleeve away from and exposing the ablation element of the ablation device.
