Prosthesis for middle ear ossicular chain reconstruction; replaces non-functional ossicles. Device features trimmable shaft and tiltable head for angulation against tympanic membrane. Used by ENT surgeons in clinical settings. Head composed of Hydroxylapatite; shaft composed of Plasti-Pore. Provides structural replacement to restore sound conduction.
Clinical Evidence
No clinical data provided; substantial equivalence based on design similarity and established material properties of Hydroxylapatite.
Technological Characteristics
Materials: Hydroxylapatite (head), Plasti-Pore (shaft). Design: Trimmable shaft, tiltable head for angulation. Classification: Total Ossicular Replacement Prosthesis (21 CFR 874.3450) and Partial Ossicular Replacement Prosthesis (21 CFR 874.3495).
Indications for Use
Indicated for patients requiring total or partial ossicular chain reconstruction due to disease, trauma, or congenital defects affecting middle ear function.
Regulatory Classification
Identification
A partial ossicular replacement prosthesis is a device intended to be implanted for the functional reconstruction of segments of the ossicular chain and facilitates the conduction of sound wave from the tympanic membrane to the inner ear. The device is made of materials such as stainless steel, tantalum, polytetrafluoroethylene, polyethylene, polytetrafluoroethylene with carbon fibers composite, absorbable gelatin material, porous polyethylene, or from a combination of these materials.
