The summary describes a physical implant (lumbar cage) and its mechanical testing, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
Explanation: The device is indicated for use in patients with degenerative disc disease (DDD) and requires interbody fusion, which is a medical treatment aimed at alleviating pain and restoring function.
No
This device is a lumbar cage system, an intervertebral fusion device used to treat degenerative disc disease. It is an implantable medical device used for treatment, not for diagnosing a medical condition. The diagnosis is made by "history and radiographic studies."
No
The device description clearly states it is an intervertebral fusion device made from PEEK with titanium markers, indicating it is a physical implant, not software. The performance studies also focus on mechanical testing of the physical device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The provided text describes a physical implantable device (a lumbar cage system) used in surgery to fuse vertebrae in the spine. It is used in vivo (within the body), not in vitro (in a lab setting with specimens).
- Lack of Specimen Analysis: There is no mention of analyzing any biological specimens from the patient. The device is a structural implant.
Therefore, based on the provided information, the Cortina™ Lumbar Cage System is a surgical implant, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Cortina™ Lumbar Cage System is indicated for use in patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1 whose condition requires the use of interbody fusion combined with supplemental fixation. The interior of the Cortina™ Lumbar Cage System should be packed with autogenous bone graft (i.e. autograft). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non- operative treatment.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Cortina™ Lumbar Cage System has been tested in the following test modes:
- Static axial compression per ASTM F2077-11
- Dynamic axial compression per ASTM F2077-11
- Static subsidence per ASTM F2267-04
- Static expulsion per ASTM DRAFT F-04.25.02.02
The results of this non-clinical testing show that the strength of the Cortina™ Lumbar Cage System is sufficient for its intended use and is substantially equivalent to legally marketed predicate devices.

(a)
Identification. An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.(b)
Classification. (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval.
(c)
Date premarket approval application (PMA) or notice of product development protocol (PDP) is required. Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

Dear Mr. Maxwell:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
