The 510(k) summary describes a mechanical implant for spinal fusion and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML. The modifications described are purely related to device size and material.
Yes.
The device is intended for use with an interbody cage as an adjunct to fusion for patients with degenerative disc disease, specifically to achieve stabilization and promote fusion in the lumbar spine. This directly addresses a medical condition to restore normal function and alleviate pain, classifying it as a therapeutic device.
No
Explanation: The device is a posterior, non-pedicle supplemental fixation device intended to achieve stabilization to promote fusion, not to diagnose a medical condition.
No
The device description clearly states it is a physical implant system made of titanium alloy, designed for surgical implantation in the lumbar spine. It is a hardware device, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's a "posterior, non-pedicle supplemental fixation device intended for use with an interbody cage as an adjunct to fusion at a single level in the lumbar spine." This describes a surgical implant used in vivo (within the body) to provide structural support.
- Device Description: The description details a physical implant made of titanium alloy that is attached to the spinous processes. This is a mechanical device, not a diagnostic test performed in vitro (outside the body) on biological samples.
- No mention of diagnostic testing: The text does not mention analyzing biological samples (like blood, urine, tissue, etc.) to diagnose a condition or provide information about a patient's health status.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a surgical implant used for structural support and stabilization.

Intended Use / Indications for Use
The coflex-F Implant System is a posterior, non-pedicle supplemental fixation device intended for use with an interbody cage as an adjunct to fusion at a single level in the lumbar spine (L1-S1). It is intended for attachment to the spinous processes for the purpose of achieving stabilization to promote fusion in patients with degenerative disc disease - defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies - with up to Grade 1 spondylolisthesis.

Device Description
The coflex-F Implant System is a spinous process fixation device that stabilizes the spinous processes and spine to act as an adjunct to fusion. It consists of a single, Ushaped component, fabricated from medical grade titanium alloy (Ti6Al4V). A set of two wings extends vertically from the superior long arm of the device, with a second set of wings extending below the inferior long arm. A screw and sleeve are inserted through a prepared hole and fixes the crimped wings to the superior and inferior spinous processes.
The purpose of this Special 510(k) is to add small- and medium-sized coflex-F Short devices to the coflex-F Implant System. The modifications are intended to allow the operating surgeon to better accommodate various patient anatomies. The modifications do not affect the intended use of the device or alter the fundamental scientific technology of the device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Finite element analysis and engineering rationale demonstrated that the addition of new components did not introduce a new worst case. Additionally, biocompatibility tests per ISO 10993 (i.e., irritation and sensitization) were conducted on materials used for devicespecific instruments. The results demonstrate that the acceptance criteria defined in the Design Control Activities Summary were met.

§ 888.3050 Spinal interlaminal fixation orthosis.
(a)
Identification. A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.(b)
Classification. Class II.

Indications For Use:
The coflex-F Implant System is a posterior, non-pedicle supplemental fixation device intended for use with an interbody cage as an adjunct to fusion at a single level in the lumbar spine (L1-S1). It is intended for attachment to the spinous processes for the purpose of achieving stabilization to promote fusion in patients with degenerative disc disease - defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies - with up to Grade 1 spondylolisthesis.

Predicate Device(s):
The modified coflex-F Short is substantially equivalent to the predicate coflex-F Implant (Paradigm Interspinous Fusion Plate) previously cleared in K093438 with respect to indications, design, function, and materials.
Substantial Equivalence:
Finite element analysis and engineering rationale demonstrated that the addition of new components did not introduce a new worst case. Additionally, biocompatibility tests per ISO 10993 (i.e., irritation and sensitization) were conducted on materials used for devicespecific instruments. The results demonstrate that the acceptance criteria defined in the Design Control Activities Summary were met and the coflex-F Short is substantially equivalent to the predicate device(s).
Conclusion:
The coflex-F Short is substantially equivalent to previously cleared devices with respect to its indications for use, design, function, and materials.
