Patent ID: 7857810

Claim:
An irrigated ablation electrode assembly for use with an irrigated catheter device comprising: a proximal member having at least one passageway for a fluid, the passageway extending radially from a central axis of the irrigated ablation electrode assembly toward an outer portion of the proximal member to an outlet; and an electrically conductive distal member having a first end and a second end and having at least one temperature sensor located within the distal member, wherein one of the first end and the second end of the distal member is configured to receive only a portion of the proximal member such that the portion of the proximal member is disposed internally relative to the distal member, wherein the at least one passageway and the outlet are not positioned longitudinally between the first and second end of the distal member and are fully insulated and separated longitudinally from the distal member and the at least one temperature sensor of the distal member by a poor thermally conductive material to provide a multi-piece electrode assembly configured to couple with said catheter device.
