ABSTRACT:
An apparatus for transferring fluids into and out of the inner ear through the round window membrane. The apparatus includes a cover member sized for placement over the round window niche. Fluid delivery and fluid extraction conduits are provided which are operatively connected to the cover member so that fluids can pass therethrough. The cover member is positioned over the niche to create a fluid-recieving zone between the cover member and the round window membrane. As a result, fluids can be delivered into or withdrawn from the zone. Alternatively, a single conduit may be used for fluid delivery and extraction. Another variation uses a compressible cover member positioned within the round window niche to form a fluid-receiving zone between the cover member and the round window membrane. The same type of conduit system described above is attached to the compressible cover member.
