Acoustic bellows type round window transducer for middle-ear implants

Clinical Biomechanics
Abstract This study describes the development of output devices for round window middle-ear implants (RW-MEIs). To improve the problems of output devices that directly apply sound pressure to RW, acoustic bellows type RW transducer (ABRT) was implemented by combining a small bellows, an acoustic tube, and a balanced armature driver (BA).

Assessment of drug permeability through an ex vivo porcine round window membrane model

iScience, 2023
Summary: Delivery of pharmaceutical therapeutics to the inner ear to treat and prevent hearing loss is challenging. Systemic delivery is not effective as only a small fraction of the therapeutic agent reaches the inner ear.
