1. A neural interface for interfacing with a target vessel, comprising:
a first arm, a second arm, and a center portion positioned between the first arm and the second arm, wherein the first arm includes a first array of segmented individual electrodes and the second arm includes a second array of segmented individual electrodes, wherein the segmented individual electrodes of the first array and the segmented individual electrodes of the second array are each interconnected with the other segmented individual electrodes of their corresponding array via an interconnect, and wherein the first arm, the second arm and the center portion are each formed of a flexible material that is configured to enable each of the first arm, the second arm and the center portion to self-size to a surface of the target vessel when the neural interface is released at a position along the target vessel, and further wherein none of the first arm, the second arm nor the center portion form a closed circumscribed circular arc around the target vessel at any point along a length of the target vessel; and
a spinal portion configured to house electrical conductors for the first electrode and the second electrode, the spinal portion being connected to one or more of the first arm, the center portion and the second arm,
wherein the first electrode and the second electrode are embedded in the flexible material,
wherein each of the first arm, the second arm and the center portion are configured to form an at least partially circular arc around the target vessel with at least one open end,
wherein each of the first arm and the second arm include a deployment feature positioned near the at least one open end, wherein each deployment feature is configured to be griped by a deployment tool and pulled back to open each of the at least partially circular arcs formed by each of the first arm and the second arm, and enable the first arm and the second arm to be placed on the target vessel, and
wherein the flexible material is biased to enable the first arm and the second arm to self-size to fit around the target vessel when the deployment tool releases each deployment feature.
