    Abstract: An electrode support structure assembly is provided comprising an electrode support structure including a plurality of splines. Each of the plurality of splines can have a proximal end portion and a distal end portion. The assembly further comprises a first element defining an axis and comprising an outer surface. The outer surface comprises a plurality of slots configured to receive the distal end portion of each of the plurality of splines. The first element is configured such that the distal end portion of each of the plurality of splines may move with respect to each slot. In accordance with some embodiments, the distal end portion of each of the plurality of splines comprises a section configured for engagement with the first element, wherein the section comprises a shoulder.

    Abstract: A system for providing irrigation fluid during ablation of tissue includes a catheter, an electrode assembly, at least one thermal sensor adapted to be connected to the catheter, and a control system. The electrode assembly is adapted to be connected to an ablation generator. The thermal sensor is adapted to be operatively connected to an electronic control unit (ECU). The ECU receives as an input temperature measurement data from the thermal sensor; determines a power delivery rate value for the ablation generator responsive to the temperature measurement data; and outputs the power delivery rate value. The control system also delivers irrigation fluid to the irrigated catheter at a first flow rate in a first time period and at a second flow rate in a second time period that is temporally after the first time period. The second flow rate is at least half of the first flow rate.
