Microneedle-endoscope for drugging and sampling of inner ear

This technology is a microneedle-endoscope capable of perforating the round window membrane of the inner ear, allowing for drug delivery and sampling of inner ear fluids for therapeutics and diagnostics.

Unmet Need: Methods for drugging and/or sampling of the inner ear

Current methods to sample and/or deliver drugs to the inner ear are largely restricted by their invasiveness and potential long-term complications such as trauma and hearing loss. The round window membrane is a major physical barrier to the inner ear that requires careful consideration to maintain its integrity and prevent long-term damage. Furthermore, methods that allow for both sampling and drug delivery are lacking.

The Technology: Microneedle-Endoscope allows for drug delivery and sampling of inner ear

This device is fitted with a microneedle head and leverages endoscopic, camera-guided precision to carefully perforate the round window membrane of the inner ear. Capable of both drug delivery and fluid sampling, this technology safety traverses a major physical barrier to the inner ear without disrupting its structural integrity and mitigating potential long-term concerns such as hearing loss.

Applications:

  • Diagnostic tool for sampling of the inner ear
  • Drug delivery device for accessing the inner ear
  • Clinical tool for perforating the round window membrane

Advantages:

  • Safely navigates the round window membrane without undermining its integrity
  • Allows for high precision with camera guidance
  • Can both deliver therapeutics and sample inner ear fluid for diagnostic purposes
  • Minimally invasive
