Abstract:
1. A catheter device configured for vascular access, comprising: an elongate body extending between a proximal end and a distal end, wherein the elongate body includes a lumen configured to receive a fluid; an ablation electrode configured to provide ablative energy, wherein the ablation electrode is located distally along the elongate body and includes an inner surface, the inner surface defining a passageway fluidly connected to the lumen of the elongate body, wherein the ablation electrode includes a plurality of irrigation apertures fluidly connected to the lumen; a sensor configured to provide a signal representative of temperature; and an insulating chamber extending at least partially about an outer surface of the ablation electrode, wherein the outer surface has a diameter greater than a diameter of the inner surface, wherein the insulating chamber is configured to at least partially insulate the sensor from the ablation electrode, wherein the irrigation apertures are outside of the insulating chamber.
