Curved biodegradable microneedles for application to the outer surface of blood vessels are produced to enhance drug delivery to vascular tissues suffering from hyperplasia or atherosclerosis. Spatially discrete thermal drawing and post-annealing processes are employed to fabricate microneedles on a curved surface. Insertion of microneedles into arteries in vivo and ex vivo is demonstrated, and their mechanical properties and drug-delivery function are studied.
