ABSTRACT:
A stapedial prosthesis includes a body defining a bucket and a shaft, and a bail handle coupled to the bucket. The bucket is preferably adjustable in diameter to fit the incus lenticular process. The shaft preferably has a varying diameter, with a central portion of a smaller diameter than a distal portion which aids in depth perception during implantation and reduces mass to permit better sound energy transmission by the prosthesis. The bail handle is preferably spring-loaded and preferably constructed of titanium. The bail handle is preferably coupled to the body without crimping, twisting or welding and preferably biases the incus toward the bucket. A method of implanting a stapedial prosthesis is also provided.
