1. A catheter configured to be inserted into a body part of a living subject, and comprising:
a shaft assembly having a proximal end and a distal end, the shaft assembly extending along a longitudinal axis and comprising:
a deflectable segment including lumens running longitudinally in the deflectable segment;
an inner portion and an outer portion, the inner portion comprising the lumens and the outer portion disposed around an outer circumference of the inner portion; and
a braiding layer disposed between the inner portion and the outer portion; and
an expandable distal end assembly comprising a plurality of spines configured to bow radially outward from the longitudinal axis, each spine of the plurality of spines comprising a flexible printed circuit board comprising multiple electrodes disposed along the spine, the expandable distal end assembly configured to transition between an expanded configuration and a collapsed configuration;
a connector disposed at the proximal end of the shaft assembly for coupling to processing circuitry;
a plurality of cables disposed in first respective ones of the lumens, each cable of the plurality of cables electrically coupled to the connector and a respective group of the multiple electrodes, wherein each cable of the plurality of cables comprises:
a bundle of individually insulated wires, each wire of the individually insulated wires connected to a respective electrode of the multiple electrodes in the respective group;
an electrical shielding surrounding the bundle and extending from the proximal end to the distal end of the shaft assembly; and
an electrically insulating jacket surrounding the electrical shielding and sized to allow longitudinal movement of the respective cable within the respective lumen;
respective elongated members disposed in second respective ones of the lumens, and connected to the distal end; and
a manipulator connected to the elongated members and configured to actuate the distal end via the elongated members.
