An ossicular prosthesis has a shaft and an elastic engagement structure coupled to the shaft. The engagement structure at least partially defines an opening and is deformable to widen the opening to permit a portion of an ossicle to be received therein. In one embodiment, the engagement structure is formed to provide substantially three point contact against ossicular structure of various diameters. In accord with preferred materials, when the engagement structure is deformed to receive the portion of the ossicle, the stress in the engagement structure remains substantially constant throughout a majority of the deformation. The load required to deform the engagement structure into an open position is relatively small, facilitating the procedure as well as reducing the potential for damage to the intact ossicle.
