Abstract: An embodiment of a mapping probe assembly includes a body frame with a lumen therein. The body frame includes a catheter shaft region, a loop section and a transition region between the catheter shaft region and a loop section. A plurality of mapping electrodes are attached around the loop section. Electrical conductors extend through the lumen of the body frame to the mapping electrodes. In some embodiments, the loop section is skived, where a portion of the body frame is removed toward the interior of the loop section. The loop section has a generally planar loop, and further has a loop center. In some embodiments, the catheter shaft has an alignment generally perpendicular to the loop section where the alignment of the catheter shaft is along a line that intersects the planar loop proximate to the loop center.

Abstract: Medical devices and methods for using medical devices are disclosed. An example medical device may include an open-irrigated ablation catheter. The open-irrigated ablation catheter may include a catheter body, an electrode tip body with irrigation ports at a distal end, and a coolant conduit. The distal end of the coolant conduit may extend into a proximal portion of the electrode tip body. Fluid flow from the coolant conduit may be diverted proximally and/or towards the wall of the electrode tip body by one or more openings proximal of a closed distal end of the conduit or by a structure blocking and diverting flow from an open distal end of the conduit.

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.
