Abstract: An open-irrigated catheter system includes a catheter body and a tip assembly, coupled to a distal end of the catheter body. The tip assembly includes an exterior wall that is conductive for delivering radio frequency (RF) energy for an RF ablation procedure, and that defines an interior region. The exterior wall includes a number of proximal irrigation ports and a number of distal irrigation ports. At least one fluid chamber is defined within the interior region and is in fluid communication with at least one of the proximal irrigation ports and the distal irrigation ports. At least one fluid lumen extends from a fluid source, through the catheter body, to the tip assembly, and is in fluid communication with the at least one fluid chamber.

Abstract: An embodiment of an open-irrigated catheter system comprises a tip section, a distal insert, and mapping electrodes. The tip section has an exterior wall that defines an open interior region within the tip section. The exterior wall includes mapping electrode openings and irrigation ports. The exterior wall is conductive for delivering radio frequency (RF) energy for an RF ablation procedure. The irrigation ports are in fluid communication with the open interior region to allow fluid to flow from the open interior region through the irrigation ports. The distal insert is positioned within the tip section to separate the open region into a distal fluid reservoir and a proximal fluid reservoir. The mapping electrodes are positioned in the mapping electrode openings in the tip section.

Abstract: A mapping catheter includes an elongated body for inserting into patient vasculature. A distal end of the elongated body includes a distal portion that includes a plurality of electrodes, a proximal portion disposed proximal to the distal portion, and a reduced-dimension portion disposed between the proximal and distal portions. The distal end is formed, at least in part, from a memory shape material that bends into a preformed shape upon release from a confined space. The preformed shape includes a first loop formed, at least in part, by the distal portion. The first loop is transverse to a longitudinal axis of the proximal portion. The reduced-dimension portion is configured and arranged to bend such that the reduced-dimension section advances distally through the first loop when the first loop is held in a fixed position and a force is applied distally along the longitudinal axis of the proximal portion.
