Despite their demonstrated effectiveness, the long term use of microscale neuroprosthetic devices is compromised by the post-implantation tissue reaction that often forms around the device. This book studies ways to improve the tissue reaction to implanted neuroprosthesis by use of a controlled drug release mechanism, quantified by novel measurement techniques. The author describes solutions to the problem of tissue reaction around microscale neuroprostheses and an also examines an improvement in neural stimulation and recording capability.
