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.

Abstract
A multi-branch stimulation electrode is disclosed herein. The multi-branch stimulation electrode can include a plurality of branches that extend from a hub. The branches can each include one or several stimulation contacts that can deliver an electrical current to tissue contacting the stimulation contacts. The stimulation contacts can be electrically connected with the lead. The lead can extend from the hub and can be connected with the pulse generator. The branches can include features to facilitate implantation including, for example, one or several removable stiffening elements.
