The summary describes a physical implant made of standard medical materials for ossicular chain reconstruction and makes no mention of software, algorithms, or AI/ML technologies.
Yes
The device is intended for the functional reconstruction of segments of the ossicular chain and facilitates the conduction of sound waves to address conductive hearing loss. This functional restoration of the body's natural processes for improved health and quality of life aligns with the definition of a therapeutic device.
No
Explanation: The device is an ossicular replacement prosthesis, which is an implantable device for functional reconstruction of the ossicular chain to restore hearing. Its purpose is therapeutic (restoring function) rather than diagnostic (identifying or characterizing a medical condition).
No
The device description explicitly states the device is manufactured from physical materials like titanium, silicone, and hydroxylapatite, indicating it is a physical implant, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- Device Function: The description clearly states that this device is an "ossicular replacement prosthesis" intended to be implanted in the middle ear to restore hearing. It facilitates the conduction of sound waves within the body.
- Lack of Specimen Testing: There is no mention of this device being used to test any biological specimens. Its function is purely mechanical and surgical.
Therefore, based on the provided information, this device falls under the category of an implantable medical device, not an In Vitro Diagnostic.

Intended Use / Indications for Use
An 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. Ossicular replacement prostheses are indicated for the functional restoration of the ossicular chain when a conductive hearing loss is present. Indications for use include:
(a) Chronic middle ear disease,
(b) Otosclerosis,
(c) Congenital fixation of the stapes,
(d) Secondary surgical intervention to correct for a significant and persistent conductive hearing loss from prior otologic surgery, and
(e) Surgically correctible injury to the middle ear from trauma.

Intended Use - The Grace Dynamic Ossicular Replacement Prostheses have the same primary intended use as the predicate devices.
An 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. Ossicular replacement prostheses are indicated for the functional restoration of the ossicular chain when a conductive hearing loss is present. Indications for use include:
- (a) Chronic middle ear disease,
- (b) Otosclerosis,
- (c) Congenital fixation of the stapes,
- (d) Secondary surgical intervention to correct for a significant and persistent conductive hearing loss from prior otologic surgery, and
- (e) Surgically correctible injury to the middle ear from trauma.
Material(s) -- The Grace Dynamic Ossicular Replacement Prostheses are manufactured from the same materials as the predicate devices:
1
- Unalloyed titanium (ASTM F67) (i)
- (ii) Titanium alloy (ASTM F136)
- Medical Grade Silicone (iii)
- ASTM F1185 Hydroxylapatite (iv)
Comparisons
-
- The Grace Dynamic Ossicular Replacement Prostheses are similar / dissimilar to the Kurz Aerial TORP in the following ways:
- Intended use The Grace Dynamic ORP bridges the gap between footplate . and TM or the stapes and TM: whereas, the Kurz TORP bridges the gap between footplate and TM.
- Materials of construction both devices contain titanium or titanium alloy; . whereas, the Grace Dynamic Ossicular Replacement Prostheses also contains medical grade silicone and hydroxylapatite.
-
- The Grace Dynamic Ossicular Replacement Prostheses are similar to the Grace Medical K-Helix Piston in the following ways:
- Intended use The Grace Dynamic ORP bridges the gap between footplate . and TM or the stapes and TM; whereas, the K-Helix Piston bridges the gap between the footplate and the remnant of the incus.
- Materials of construction both devices contain titanium or titanium alloy; . whereas, the Grace Dynamic ORP also contains medical grade silicone and hydroxylapatite.
-
- The Grace Dynamic Ossicular Replacement Prostheses are similar / dissimilar to the Grace Medical Fixed Length TORP's in the following ways:
- . Intended use - The Grace Dynamic ORP bridges the gap between footplate and TM or the stapes and TM; whereas, the Grace Medical Fixed Length TORP bridges the gap between footplate and TM.
- Materials of construction both devices contain titanium or titanium alloy, a . medical-grade silicone sleeve, and hydroxylapatite.
Differences between the Grace Dynamic Ossicular Replacement Prostheses and the predicate devices should not affect the safety or effectiveness.
