The present disclosure describes a system for the delivery of therapeutic substances to the cavities of a patient. The system can include a wearable micropump that is fluidically coupled with a handpiece. The handpiece can be inserted, for example, into the middle ear via a surgical tympanotomy approach. The system can enable a controlled injection of a therapeutic substance directly into the patient's cavity.

Wearable micropump for therapeutic drug delivery

A system for the delivery of therapeutic substances to cavities of a patient. The system can include a handpiece tool coupled with a pump. The handpiece tool can include a shaft including a first portion of a channel coupled to a multi-input tubing. The handpiece tool can include an angled portion coupled with the shaft. The handpiece tool can include a second portion of the channel, wherein the angled portion positions a tip portion within a cavity, wherein the tip portion projects from the angled portion and includes an outlet and a third portion of the channel. The handpiece tool can include a collar a distance from the outlet, the collar configured to control a distance the tip portion projects. The handpiece tool can include a mixing chamber configured to receive the components of the drug and output the mixed drug via the third portion of the channel.

System for inner ear drug delivery via trans-round window membrane injection

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.

Apparatus and method for trans-round window membrane drug delivery

The present disclosure provides compositions and methods for treating an auditory disease in a subject in need thereof comprising administering an effective amount of a gel-based precursor that includes an inner ear-specific therapeutic compound directly into the cochlea of the subject.
