Provided herein are magnetic resonance imaging (MRI) compatible, convection-enhanced delivery (CED) cranial implant devices and related methods for performing a wide array of therapeutic and/or monitoring applications. In one aspect, the cranial implant device includes a cranial implant housing configured for intercranial implantation in a cranial opening of a subject. The cranial implant housing comprises a substantially anatomically-compatible shape, at least first and second surfaces, and at least one fluidic circuit comprising at least one cavity and at least one port that fluidly communicates with the cavity through at least the second surface, in which the cavity comprises, or is capable of comprising, at least one fluidic therapeutic agent. The device also includes at least one CED pump operably connected to the fluidic circuit, which CED pump is configured to convey the fluidic therapeutic agent from the cavity through at least one fluid conduit when the fluid conduit is operably connected to the port to maintain at least one positive pressure gradient of the fluidic therapeutic agent at least proximal to an outlet of the fluid conduit. In addition, the device also includes at least one power source operably connected at least to the CED pump. The cranial implant housing, the CED pump, and the power source are typically fabricated from one or more MRI compatible materials. Other aspects relate to various methods of treating a neurologically-related disease using the cranial implant devices, methods of monitoring therapeutic agent administration in a plurality of subjects, and methods of fabricating a cranial implant device as well as surgical methods. |
