    Abstract: A system for performing mapping and ablation functions includes a catheter sized and shaped for vascular access. The catheter includes an elongate body extending between a proximal end and a distal end and having at least one inner fluid lumen. The catheter further includes a tip section positioned proximate to the distal end of the body. The tip section includes a proximal portion and a distal portion. The distal portion can have a distal end that can be substantially planar. The system also includes one or more electrode structures exposed at the tip section such that the one or more electrode structures disposed proximate the substantially planar distal end of the tip section.

    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.
