The various prosthetic models are implanted for partial or complete reconstruction, to replace missing or malformed ossicles or in secondary procedures after tumor or trauma operations. Titanium ossicular chain reconstruction prostheses are available for the following indications: Chronic otitis media; Immobility of the stapes (otosclerosis in particular); Injury of the ossicle (trauma); Abnormal and defective formation of the middle ear; Secondary procedure to improve hearing; Revision operation on a malpositioned prosthesis ## Device Story System of titanium implants for middle ear ossicular chain reconstruction. Prosthetic models include stapes, incus, partial (PORP), total (TORP), and neomalleus prostheses. Implants replace missing, malformed, or immobile ossicles to restore sound transmission. Used by surgeons in clinical settings during otologic procedures. Implants connect structures such as the tympanic membrane, malleus, incus, and stapes footplate. Benefits include restored middle ear function and improved hearing for patients with conductive hearing loss. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Titanium ossicular chain reconstruction prostheses. Includes various models: stapes, incus, partial (PORP), total (TORP), and neomalleus. Mechanical implants designed for surgical implantation in the middle ear. ## Regulatory Identification A total ossicular replacement prosthesis is a device intended to be implanted for the total functional reconstruction of the ossicular chain and facilitates the conduction of sound waves from the tympanic membrance to the inner ear. The device is made of materials such as polytetrafluoroethylene, polytetrafluoroethylene with vitreous carbon fibers composite, porous polyethylene, or from a combination of these materials. ## Predicate Devices - Micromedics S&T Total Ossicular Replacement Prosthesis - Tubingen Titanium Prosthesis (TTP) Vario (Heinz Kurz GmbH Medizintechnik) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
