The PRADO™ Lumbar Interbody Fusion System is indicated for use in skeletally mature patients with Degenerative Disc Disease (DDD) at one or two contiguous levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have received 6 months of non-operative treatment prior to treatment with the devices. The device must be used with supplemental fixation. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis and/or stenosis at the involved level(s). Additionally, the Prado™ Lumbar Interbody Fusion System can be used as an adjunct to fusion in patients diagnosed with multilevel degenerative scoliosis and sagittal deformity. It is indicated to be used with autograft bone and/or allogenic bone graft comprised of cortical, cancellous and/or corticocancellous bone graft and/or demineralized allograft bone with bone marrow aspirate or a bone void filler cleared for use in intervertebral body fusion to facilitate fusion.
Additionally, the use of hyperlordotic devices (lordotic angle greater than 20°) are intended to be used exclusively with anterior supplemental fixation.
PRADO™ Lumbar Interbody Fusion System consists of a series of implants and device specific instruments. PRADO™ Lumbar Interbody devices are manufactured from polyetheretherketone (PEEK) or Hydroxyapatite (HA) filled Polyetheretherketone (PEEK). The superior and inferior surfaces of the implants have ridges to interface with the vertebral endplates to resist rotation and migration. Additionally, the cephalad / caudal opening of each implant is maximized to facilitate bone through growth. Lateral fenestrations are provided to encourage bone ingrowth. Tantalum markers (per ASTM F560) or titanium (per ASTM F136), are configured as rods at the extremes of the PRADO™ Lumbar Interbody Devices to allow for radiological confirmation of the positioning. The proximal face of each interbody has a threaded thru hole which is to be used to interface with the inserter.
PRADO™ Lumbar Interbody Devices are available in four footprints to coincide with the surgical approach and patient need: PRADO™ P, PRADO™ T, PRADO™ L and PRADO™ A. The implants are available in a range of sizes to accommodate variations in patient anatomy.
The provided FDA 510(k) clearance letter for the PRADO™ Lumbar Interbody Fusion System does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria, especially in the context of an AI/ML-driven medical device.
The document describes a mechanical implant (intervertebral body fusion device) and discusses its physical characteristics, materials, and non-clinical mechanical testing (ASTM F2077-18 and ASTM F2267-04), which typically involve evaluating properties like static compression, dynamic compression, expulsion, and subsidence. The clearance is based on substantial equivalence to predicate devices for these mechanical properties.
The questions you've asked (regarding acceptance criteria, sample size for test/training sets, experts for ground truth, adjudication methods, MRMC studies, standalone performance, and ground truth establishment) are highly relevant to the validation of AI/Machine Learning (ML) medical devices, particularly those that perform diagnostic or prognostic functions based on image analysis or other data.
Since the provided document is for a physical implant and not an AI/ML device, it naturally does not include the details pertinent to AI/ML validation studies. Therefore, I cannot extract the requested information from this text.
To answer your request, if this were an AI/ML device, the required information would typically be found in a separate section of the 510(k) submission, often within a "Performance Data" or "Clinical Performance Testing" section, specifically detailing the validation study for the AI algorithm.
If you intended to provide a document related to an AI/ML medical device, please provide that document, and I will be able to answer your questions.
§ 888.3080 Intervertebral body fusion device.
(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.
