1. A device for treating hearing loss by facilitating stimulation of cochlear fluid through the promontory bone, comprising:
- a diaphragm;
a body portion coupled to the diaphragm, the body portion and diaphragm defining at least a portion of a reservoir;
a neck portion extending away from the body portion, the neck portion comprising an outer diameter; and
a deformable member disposed on the neck portion, wherein at least a portion of the deformable member is configured to extending beyond the outer diameter of the neck portion when the deformable member is not compressed;
wherein the neck portion is adapted to be inserted into a channel formed in the promontory bone of the patient, the neck portion being further adapted to permit cochlear fluid to flow through the neck portion and into the reservoir;
wherein the deformable member is adapted to engage a cavity formed in the channel and hold the neck portion in the channel.
