The disclosed technology includes an expandable basket assembly for a medical probe, which may include a single unitary structure including a plurality of spines converging at a central spine intersection. The central spine intersection being positioned on a longitudinal axis of the expandable basket assembly at a distal end thereof. The single unitary structure may include a plurality of radial cutouts with each radial cutout defining an opening in each of the plurality of spines proximate the central spine intersection so that each opening extends for a length along each spine away from the central spine intersection.
