AI/ML Overview

The provided document describes Medtronic's Robotic Graft Delivery Instruments and their 510(k) summary (K230716). However, it does not contain detailed information regarding acceptance criteria, the specific study design to prove acceptance, sample sizes for test/training sets, expert qualifications, or adjudication methods. The document primarily focuses on regulatory clearance by demonstrating substantial equivalence to predicate devices and lists general performance tests conducted.

Therefore, many of the requested fields cannot be filled from the provided text.

Here's a breakdown of what can be extracted and what is missing:


Acceptance Criteria and Device Performance

The document describes general performance tests, but explicit acceptance criteria with numerical targets are not provided. The 'Description' column of the performance test table gives an indication of what was confirmed, which implicitly suggests the desired performance.

Implicit Acceptance Criteria and Reported Device Performance

TestImplicit Acceptance CriteriaReported Device Performance
Anatomical Simulated UseInstrument functionality under expected use conditions must be confirmed.Confirmed instrument functionality under expected use conditions.
Mechanical Guidance AccuracyThe subject instruments must have a maximum radial deviation within the allowable surgical tool mechanical tolerance at the bone entry surface.Confirmed that the subject instruments have a maximum radial deviation within the allowable surgical tool mechanical tolerance at the bone entry surface.
Depth Control AnalysisThe graft delivery instruments must engage facet defects created by Mazor X Stealth Edition facet decortication tools.Confirmed the graft delivery instruments engage facet defect created by Mazor X Stealth Edition facet decortication tools.

Additional Information on the Study:

  • Sample size used for the test set and the data provenance:

    • Sample Size: Not specified in the document.
    • Data Provenance: Not specified (e.g., country of origin, retrospective/prospective). The testing appears to be laboratory-based ("Anatomical Simulated Use," "Mechanical Guidance Accuracy," "Depth Control Analysis").
  • Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • Not specified. The document refers to "expected use conditions" and engagement with "facet defect created by Mazor X Stealth Edition facet decortication tools," suggesting a simulated environment rather than human expert reads of clinical images or data for ground truth.
  • Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    • Not applicable/Not specified. The tests described are functional and mechanical in nature, not involving interpretation by multiple adjudicators.
  • 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:

    • No. The device is a surgical instrument, not an AI-assisted diagnostic tool. This type of study is not relevant to this device.
  • If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • Not applicable. The device is a surgical instrument. The performance testing "confirmed instrument functionality under expected use conditions" and "mechanical guidance accuracy," implying standalone functional and mechanical testing of the instrument itself rather than an algorithm.
  • The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • The "ground truth" for the performance tests appears to be objective, measurable mechanical and functional standards (e.g., "allowable surgical tool mechanical tolerance," "engage facet defect"). It is not based on expert consensus, pathology, or outcomes data in the typical sense of a diagnostic device.
  • The sample size for the training set:

    • Not applicable. This device is a mechanical surgical instrument, not an AI/machine learning model that requires a training set.
  • How the ground truth for the training set was established:

    • Not applicable, as there is no training set for this type of device.

Indications for Use: V.

Medtronic Surgical Instruments are intended to be used during the preparation and placement of Medtronic implants during spinal surgery to assist the surgeon in precisely locating anatomical structures in either open, or minimally invasive, procedures. Medtronic Surgical Instruments are specifically designed for use with the MAZOR X Stealth™ Edition, which is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as a vertebra, can be identified relative to a CT or MR-based model, fluoroscopy images, or digitized landmarks of the anatomy. Medtronic Surgical Instruments can be navigated or non-navigated manual instruments that may or may not be guided through the MAZOR X Arm Guide. Medtronic surgical drills shall only be used through the MAZOR X arm guides, Medtronic cannulas, and Medtronic drill guides. Some of the Medtronic Surgical Instruments are also compatible with the IPCTM POWEREASE™ System. An instrument may incorporate a measuring function which has uses as described on the label and the instrument.

Comparison of the Technological Characteristics with the Predicate Device: VI.

The robotic graft delivery instruments are intended to be used during the preparation and placement of graft material during spinal surgery and are specifically designed for use with trajectory guidance through the robotic arm. Like the predicate device, the subject instruments work through an arm guide for trajectory guidance. The subject instruments have similar designs, principle of operation, fundamental scientific technology, material, intended use, as the primary predicate device and incorporate the similar design features to

{5}------------------------------------------------

K230716

enable arm guide compatibility. Additionally, the subject instruments have similar designs and fundamental scientific technology as the reference predicate.

The subject instruments are assembled and placed through a cannula the same as the primary predicate device to allow access to the surgical site through the arm guide. Unlike the primary predicate, the subject instruments are used to deliver graft material to the surgical site similar to the reference predicate,

Performance Data: VII.

The following testing was performed on the Robotic Graft Delivery instrument to ensure the functionality and compatibility with the identified Medtronic MAZOR X Stealth Arm Guide. The table below provides a summary of the performance testing completed:

TestDescription
Anatomical SimulatedUseConfirmed instrument functionality under expected use conditions
Mechanical GuidanceAccuracy(Surgical ToolsMechanicalTolerance)Confirmed that the subject instruments have a maximum radial deviation within the allowable surgical tool mechanical tolerance at the bone entry surface. This is a component of the total robotic guidance trajectory accuracy.
Depth ControlAnalysisConfirmed the graft delivery instruments engage facet defect created by Mazor X Stealth Edition facet decortication tools.

VIII. Conclusions

The robotic graft delivery instruments have shown through comparison and testing to be substantially equivalent to the identified predicate devices.
