Abstract
An improvement in bail-and-bucket, piston-type stapedial prostheses in which the bail is pivotally mounted to rotate about the open end of the bucket. Means are provided on the bucket for permitting overcenter pivotal movement of the bail in one direction and thereafter preventing overcenter pivotal movement of the bail in the opposite direction. The preferred means for accomplishing this function is an opposed pair of cam surfaces mounted on the bucket.
