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.

An irrigated high density electrode catheter, comprising:
- a catheter shaft including a proximal end and a distal end, the catheter shaft defining a catheter shaft longitudinal axis;
- a flexible tip portion located adjacent to the distal end of the catheter shaft;
- and
- an irrigated coupler disposed on the distal end of the catheter shaft configured to discharge fluid over the flexible tip portion.

A catheter, comprising:
- an elongate shaft including a proximal end and a distal end, the elongate shaft defining a shaft longitudinal axis;
- a coupler disposed within a distal end of the elongate shaft, the coupler defining a first sensor groove and a second sensor groove in an exterior surface of the coupler and a coupler longitudinal axis;
- and
- a first five degree of freedom magnetic position sensor disposed in the first sensor groove and a second five degree of freedom magnetic position sensor disposed in the second sensor groove, the first five degree of freedom magnetic position sensor defining a first sensor longitudinal axis and the second five degree of freedom magnetic position sensor defining a second sensor longitudinal axis, wherein:
- the first sensor longitudinal axis and the second sensor longitudinal axis are divergent with respect to each other and the coupler longitudinal axis.
