Device Description

The Minuteman devices consist of bilateral Plates and a Body/Post that connects the Plates, identical to the predicate constructs. The Plate components include several spiked grips at the ends of each Plate for attachment to the spinous processes. The Minuteman devices are available in multiple sizes to accommodate varying patient anatomy. The Minuteman devices are made from Ti6Al4V and Ti6Al4V ELI. The HA versions of the Minuteman devices have an additional hydroxyapatite coating on the distal regions of the device.

AI/ML Overview

This document describes the marketing approval for the Spinal Simplicity Minuteman G3 MIS Fusion Plate system. It is a 510(k) submission, meaning the manufacturer is demonstrating that its device is substantially equivalent to legally marketed predicate devices, rather than proving its safety and effectiveness from scratch. Therefore, the information provided focuses on the equivalence to existing devices and updates to indications for use, rather than a detailed study proving novel acceptance criteria for the device itself.

Based on the provided text, here's a summary of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance:

The document explicitly states: "There are no changes to the functional characteristics from the previously cleared versions of each Minuteman device. The only differences are labeling updates. Therefore, no non-clinical performance data has been submitted." and "The only difference is regarding updated Indications for Use."

This indicates that the acceptance criteria for the device's performance are implicitly met by its substantial equivalence to previously cleared devices. Specific numerical performance criteria (e.g., tensile strength, fatigue life) are not detailed in this regulatory summary because the device itself hasn't changed. The acceptance for this 510(k) is based on the updated Indications for Use being supported by existing data and the design being identical to cleared predicates.

The "reported device performance" is essentially that it performs identically to its predicate devices, which have already met their respective acceptance criteria.

2. Sample size used for the test set and the data provenance:

  • Test set sample size: Not applicable or not explicitly stated in the context of this 510(k) summary for this submission. This submission is for an updated Indications for Use on an already cleared device, where the device itself hasn't changed technologically or functionally.
  • Data provenance: "Clinical data from a prospective, randomized clinical study of the Minuteman was presented." No country of origin is specified. The study was prospective.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This information is not provided in the document. The clinical study mentioned would have involved clinical endpoints, but the method for establishing "ground truth" (e.g., through expert diagnosis or objective measures) is not detailed.

4. Adjudication method for the test set:

This information is not provided in the document.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

Not applicable. This device is a physical spinal implant, not an AI-powered diagnostic or assistive technology.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

Not applicable. This is a physical medical device.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

The clinical study evaluated "satisfactory clinical outcomes." This implies that outcomes data (e.g., patient-reported outcomes, objective measures of fusion, reduction in pain) were used, likely assessed by clinical experts.

8. The sample size for the training set:

Not applicable. As a physical device, there is no "training set" in the context of machine learning. The clinical study described in section 9 would represent the data used to support the device's indications.

9. How the ground truth for the training set was established:

Not applicable for a training set. For the clinical study that supported the device, the summary states: "The Minuteman was compared to surgical decompression in the treatment of skeletally-mature patients diagnosed with lumbar spinal stenosis with or without accompanying spondylolisthesis. The data showed that the Minuteman provided satisfactory clinical outcomes." This suggests the efficacy was established by comparing clinical outcomes between the Minuteman device and surgical decompression in a prospective, randomized clinical trial. The specific metrics for "satisfactory clinical outcomes" are not elaborated upon in this document but would typically involve patient-reported pain scores, functional assessments, and potentially radiographic evidence of fusion.

§ 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.
