Intended Use

The CarboClear® Hybrid Pedicle Screw System is intended to provide rigid immobilization and stabilization of lumbar and/or sacral segments as an adjunct to fusion in patients with degenerative disc disease (DDD) at up to three levels from L2 to S1, with up to Grade I spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. Patients should be skeletally mature and have at least six months of nonoperative treatment.

The CarboClear® Hybrid Pedicle Screw System is intended to be used with intervertebral body fusion device/s implanted at the same spinal level/s with autogenous and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft.

Device Description

The CarboClear® Hybrid Pedicle Screw System is composed of implants in various dimensions, used to build a spinal construct; and of a set of instruments, intended to assist in the insertion and placement of the implants.

The CarboClear® Hybrid Pedicle Screws, including CarboClear® Hybrid Fenestrated Screws, are made of carbon fiber-reinforced polyetheretherketone (CFR-PEEK), with titanium alloy tulip. Their threaded portion is encased within a thin titanium shell. They are used with a compatible titanium alloy set screw, and with CarboClear CFR-PEEK rods. The implants may include tantalum markers. CarboClear titanium alloy rod is also offered.

The implants are supplied sterile, and are intended for single use.

The CarboClear® Hybrid implants may be implanted in an open approach or using a minimally invasive surgery (MIS) approach.

AI/ML Overview

This document is a 510(k) premarket notification decision letter from the FDA regarding the CarboClear® Hybrid Pedicle Screw System. It declares the device substantially equivalent to legally marketed predicate devices.

However, the provided text does not contain any information about acceptance criteria or a study proving the device meets those criteria in the context of AI/ML performance. The document focuses on the mechanical and material properties of a surgical implant (pedicle screw system), not a software device or an AI/ML algorithm.

Therefore, I cannot extract the requested information (acceptance criteria table, sample size, expert information, adjudication, MRMC, standalone performance, ground truth, training set details) from this document as it pertains to a different type of medical device and regulatory review process.

The document covers:

  • Device Name: CarboClear® Hybrid Pedicle Screw System
  • Regulation Name: Thoracolumbosacral Pedicle Screw System (21 CFR 888.3070)
  • Regulatory Class: Class II
  • Purpose of Submission: Expansion of indications for use (specifically, longer rods).
  • Performance Data Mentioned: Previously conducted static and dynamic tests according to ASTM F1717 and ASTM F1798, showing comparability to predicate devices.
  • Conclusion: Substantial equivalence to predicate devices based on intended use, design, dimensions, materials, technological characteristics, principles of operation, and performance.

It explicitly states: "No new performance testing was necessary to support the current submission." This further confirms that no new clinical or AI/ML performance study was conducted for this specific submission.

To answer your request, you would need a document related to an AI/ML medical device submission, typically found in a "Clinical Performance" or "Software Validation" section of a 510(k) summary or a similar regulatory filing for AI/ML products.

§ 888.3070 Thoracolumbosacral pedicle screw system.

(a)
Identification. (1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems.
(b)
Classification. (1) Class II (special controls), when intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards;
(ii) Compliance with mechanical testing standards;
(iii) Compliance with biocompatibility standards; and
(iv) Labeling that contains these two statements in addition to other appropriate labeling information:
“Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis). The safety and effectiveness of these devices for any other conditions are unknown.”
“Precaution: The implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.”
(2) Class II (special controls), when a rigid pedicle screw system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment. These pedicle screw systems must comply with the following special controls:
(i) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(ii) Non-clinical performance testing must demonstrate the mechanical function and durability of the implant.
(iii) Device components must be demonstrated to be biocompatible.
(iv) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(v) Labeling must include the following:
(A) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(B) Intended use and indications for use, including levels of fixation;
(C) Identification of magnetic resonance (MR) compatibility status;
(D) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user; and
(E) Detailed instructions of each surgical step, including device removal.
(3) Class II (special controls), when a semi-rigid system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion for any indication. In addition to complying with the special controls in paragraphs (b)(2)(i) through (v) of this section, these pedicle screw systems must comply with the following special controls:
(i) Demonstration that clinical performance characteristics of the device support the intended use of the product, including assessment of fusion compared to a clinically acceptable fusion rate.
(ii) Semi-rigid systems marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with the special controls in paragraphs (b)(2)(i) through (v) and paragraph (b)(3)(i) of this section.
