Abstract: A catheter includes an elongate shaft, an electrode assembly, a connective stem, a coupler, a first magnetic position sensor, and a second magnetic position sensor. The electrode assembly includes microelectrodes. The connective stem includes a first connective stem member and a second connective stem member. The connective stem defines a first sensor receptacle and a second sensor receptacle in an exterior surface of the connective stem. The coupler is configured for coupling with the connective stem. The first magnetic position sensor is disposed in the first sensor receptacle and elongated along a first sensor longitudinal axis. The second magnetic position sensor disposed in the second sensor receptacle and elongated along a second sensor longitudinal axis that is not parallel to the first sensor longitudinal axis.

Abstract: An irrigated high density electrode catheter can comprise a catheter shaft. The catheter shaft can include a proximal end and a distal end and can define a catheter shaft longitudinal axis. A flexible tip portion can be located adjacent to the distal end of the catheter shaft. An irrigated coupler can be disposed on the distal end of the catheter shaft and can be configured to discharge fluid over the flexible tip portion.
