Abstract
The present solution provides systems and methods for trans-round window membrane drug delivery. As an overview, a system can include a micropump that is connected to a flexible cannula. The cannula can be threaded through a handpiece that can be used to pierce the round window membrane of a patient. Using the handpiece, the cannula can be inserted through the round window membrane to improve the distribution of the delivered drug throughout the inner ear. The present solution can function as a small implantable or wearable device that can be used for both chronic and acute trans-round window membrane drug delivery. With this configuration, the micropump can constantly or intermittently deliver, over a period of days to months, small volumes of drugs from an internal reservoir.
