The Reliance Lumbar IBF System is indicated for intervertebral body fusion of the spine in skeletally mature patients. The device systems are designed for use with autogenous bone graft to facilitate fusion. One device may be used per intervertebral space. The implants are intended to be used with legally cleared supplemental spinal fixation cleared for the implanted level. Additional supplemental fixation is not necessary for the Lumbar IBF-S if the integrated screws are implanted.

The Reliance Lumbar IBF System, when used as an Intervertebral Body Fusion device is also intended for use at either one level or two contiguous levels in the lumbar spine, from L2 to S1, for the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The lumbar device is to be used in patients who have had six months of non-operative treatment.

The Reliance Lumbar IBF System is comprised of lumbar intervertebral body fusion devices and associated surgical instruments. This submission adds a line extension, the Reliance Lumbar IBF-S devices, which consist of spacers made of PEEK Optima LT1 with Tantalum markers, and integrated screws, faceplates, and locking plates manufactured from titanium alloy.

The provided text describes a medical device, the Reliance Lumbar IBF System, and its regulatory clearance process (510(k)). It does not include details about acceptance criteria, device performance metrics, or any clinical studies involving human readers or AI algorithms. The "Performance Data and Substantial Equivalence" section only mentions mechanical testing performed on the device to establish substantial equivalence to predicate devices, focusing on physical properties rather than diagnostic performance.

Therefore, I cannot extract the requested information from the provided text as it is not present. The document focuses on regulatory approval based on substantial equivalence to existing medical devices, not on the diagnostic performance or AI-assisted interpretation of medical images.
