Apparatus and method for trans-round window membrane drug delivery |
abstract |
The present solution provides trans-round window membrane (RWM) drug delivery. As an overview, the system can include a micropump that is connected to a flexible cannula. The cannula can include a stiffened and sharpened tip to facilitate insertion through the RWM. The cannula can be inserted through the RWM 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-RWM 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. |
