US 10,595,990 B2 · Osseointegrative adjustable ossicular prosthesis

Abstract

An otologic prosthesis is disclosed. In accordance with some embodiments, the device includes a set of crimping prongs comprising a lattice structure provided on a surface of each crimping prong in the set of crimping prongs to support and promote osseointegration. In accordance with some embodiments, the stem and the TM plate are separate pieces configured to be attached by a snap-fit mechanism. In accordance with some embodiments, the device is an adjustable length prosthesis with an internalized sizing mechanism. In accordance with some embodiments, the device is adjustable by a rotatable joint that facilitates rotation of a first stem section with respect to a second stem section for adjustment and readjustment on a patient-specific basis.
