1. A neurostimulation system, comprising:

  • (a) an implantable neurostimulation pulse generator configured to generate one or more neurostimulation electrical signals;

    (b) a multi-branch electrode array configured to be coupled to the pulse generator and to transmit the one or more non-ablative neurostimulation electrical signals to a nerve tissue, the multi-branch electrode array comprising;

    (i) a plurality of branches, wherein at least some of the branches each include a plurality of electrode contacts;

    (ii) wherein, when in a deployed configuration, the plurality of branches diverge away from one another such that distal tips of the branches are spaced farther apart than proximate portions of the branches;

    (iii) wherein, when in the deployed configuration, the plurality of branches are in a substantially planar arrangement;

    (iv) wherein at least some of the branches comprise a stiffening component connected by a stiffening component hub, the stiffening component hub comprising a plurality of stiffening components, wherein the stiffening components are simultaneously displaceable by displacement of the stiffening component hub.
