1. A medical probe, comprising:
a tubular shaft including a proximal end and a distal end, the tubular shaft extending along a longitudinal axis;
an expandable basket assembly proximate the distal end of the tubular shaft, the basket assembly comprising a first unitary tripodic structure and a second unitary tripodic structure, each tripodic structure formed from a respective planar sheet of material that includes three linear spines converging at a respective central spine intersection, each spine of each tripodic structure including a respective end connected to the distal end of the tubular shaft, the central spine intersection of each tripodic structure being positioned on the longitudinal axis at a distal end of the basket assembly; and
one or more electrodes coupled to each of the spines, each electrode defining a lumen through the electrode so that the spine extends through the lumen of each of the one or more electrodes.
