Apparatus and method for delivering therapeutic and/or other agents to the inner ear and to other tissues

摘要

An apparatus may include a needle for sustained delivery of drugs and other agents to the inner ear or other tissues of a human or an animal. The needle can include an insertion stop, and can be placed through the round window membrane or through a surgically-prepared hole in a bone. The needle can be in fluid communication with a port and/or with a micro-infusion or osmotic pump. A cochlear implant electrode can be used instead of a needle.
