Abstract:
1. A flexible spirally-rolled polymer microtube for in vivo monitoring and treatment of brain injuries, the microtube integrally comprising one or more microsensors and one or more microchannels, wherein the microsensors monitor one or more parameters and the microchannels are capable of delivering substances to the brain and removing substances from the brain, and wherein the one or more microchannels is each from 1 μm to 2000 μm in length, width, and depth, and wherein each of the one or more microchannels has a microchannel interior, with each microchannel interior having at least two microchannel openings which are oriented perpendicular to a length along the longitudinal axis of the microchannel interior, wherein the microtube has an opening at each longitudinal end, and wherein the at least two microchannel openings extend inwardly toward a central axis of the longitudinal length of the microtube and away from a polymer layer of the microtube.
