Articulated Neural Electrode Assembly
First Claim
1. An articulated electrode assembly, said assembly comprising:
- a set of paddles, at least one paddle comprising;
a support member;
at least one coupling member configured for detachable coupling to another paddle, said at least one coupling member spanning between said paddles;
a set of electrical contacts carried by said support member; and
an electrical lead wire at least partially carried by said support member and coupled to at least one electrical contact, wherein at least one saddle is sized and configured for implantation at a neuroanatomical location within a patient.

Abstract
Apparatuses, devices, and/or systems that may be configured for placement at one or more cortical and/or other neuroanatomical sites to provide electrical stimulation and/or monitor neuroelectric activity within a patient. In one embodiment, an implantable articulated electrode assembly may include an array of electrodes or electrical contacts carried by a support member configured to be implanted or positioned relative to a set of neuroanatomical sites. Various embodiments of the articulated electrode assemblies may comprise multiple portions, segments, paddles, and/or panels having spatially divergent placement capabilities in relation to one another. Such segments or panels may be positioned in a variety of manners relative to each other and/or one or more neuroanatomical sites or locations, which may facilitate establishment of an intended type of stimulation field distribution and/or monitoring configuration.
