1. A catheter, comprising:
a shaft having a proximal end portion and a distal end portion; and
a tip assembly coupled to the distal end portion of the shaft, the tip assembly including (a) a plurality of cells formed of struts separated by joints, wherein the struts are moveable based on a flexibility of the joints, and (b) one or more sensors, wherein the one or more sensors are disposed on the struts, wherein:
at least a portion of each cell in the plurality of cells is configured to conduct and deliver ablative electrical energy along a majority of its length directly to a target tissue of a patient,
a sensor of the one or more sensors is electrically isolated, via an electrically insulating material, from a respective strut in the plurality of cells, the sensor mounted to the respective strut,
the electrically insulating material is positioned between the sensor and the respective strut, and
the sensor of the one or more sensors is configured to measure an electrophysiological signal corresponding to electrical activity of the tissue in an area of an anatomic structure local to the sensor, the electrical activity useable for mapping the anatomic structure.
