    摘要: 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.

    摘要: The present disclosure provides a handpiece for trans-canal delivery of a therapeutic substance to the inner ear. The handpiece can be inserted into the middle ear via a surgical tympanotomy approach. The handpiece can be integrated with a micropump and a fluid reservoir. The handpiece can enable a controlled injection of a therapeutic substance directly through the round window membrane and into the inner ear. The direct delivery of the therapeutic substance to the inner ear can enable the delivery of a precise amount of therapeutic substance into the inner ear. The micropump can include a self-contained fluid reservoir that can provide predetermined volumes of fluid to precise areas of the patient.
