US Patent 11857326 Agent-delivering neural probe devices and related systems and methods

Provided herein are a variety of neural probe devices that include an agent delivery feature via an agent coating or an agent delivery mechanism of some kind. The probe devices can include depth or cortical probes or electrodes. The agent delivery mechanisms can include, for example, a dissolvable agent delivery structure, an agent delivery lumen, a magnetically deployable cover, an iontophoretic delivery mechanism, an agent delivery cavity defined in the neural probe, or an agent reservoir with an actuable gate.
