ASTRA and AVANT Navigated Reusable Instruments are indicated for preparation and placement of SpineCraft ASTRA Spine system pedicle screws during thoracolumbar sacroiliac spinal surgery to assist surgeon in precisely locating anatomical structures in either open, minimally invasive procedures, or percutaneous, procedures.
ASTRA and AVANT Navigated Reusable Instruments are specifically designed for use with Medtronic StealthStation® System S8 (V1.2.0), 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. Use of the ASTRA and AVANT Navigated Reusable Instruments is limited to use only with ASTRA Spine System implants.
ASTRA-OCT Navigated Reusable instruments are indicated for preparation and placement of SpineCraft ASTRA-OCT Spine screws during cervico-thoracic spinal surgery to assist surgeon in precisely locating anatomical structures in open procedures.
ASTRA-OCT Navigated Reusable Instruments are specifically designed for use with Medtronic StealthStation® System S8 (V1.2.0), 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. Use of the ASTRA-OCT Navigated Reusable Instruments is limited to use only with ASTRA-OCT Spine System implants.
The ASTRA, AVANT and ASTRA-OCT Navigation instruments are non-sterile, reusable surgical instruments designed for compatibility with the Medtronic NavLock Trackers and to ultimately provide seamless interaction with the Medtronic StealthStation® System. The ASTRA and AVANT Navigation instruments are for use with ASTRA Spine System pedicle screws and the ASTRA-OCT Navigation instruments are for use with ASTRA-OCT Spine System pedicle screws. The instruments are manufactured from medical grade stainless steel. The ASTRA-OCT navigation instruments are available in same or similar diameters and lengths as the corresponding predicate Medtronic navigated instruments. This includes awls, probes, drill bits, taps and screwdrivers.
This looks like a 510(k) summary for a medical device rather than a study evaluating the performance of an AI/ML powered device. As such, it does not contain the specific information requested in the prompt regarding acceptance criteria and a study proving the device meets those criteria for an AI/ML system.
However, I can extract information related to the device's performance testing based on the provided document:
1. A table of acceptance criteria and the reported device performance
The document provides a list of performance tests conducted according to ASTM F2554-18, implying that the device performance demonstrated it "perform[s] as designed, are suitable for their intended use and are substantially equivalent to the cited corresponding predicate devices under the same test conditions." However, specific numerical acceptance criteria (e.g., "accuracy must be greater than X") and corresponding numerical performance results are not provided in this summary.
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Meet requirements of ASTM F2554-18 for positional accuracy of computer-assisted surgical systems. | "Performance testing conducted on the ASTRA, AVANT and ASTRA-OCT Navigation instruments Systems demonstrated that they perform as designed, are suitable for their intended use and are substantially equivalent to the cited corresponding predicate devices under the same test conditions." |
| Achieve specific accuracy for single point measurement. | Tested per ASTM F2554-18. Specific results not provided. |
| Achieve specific accuracy for instrument axis rotation measurement. | Tested per ASTM F2554-18. Specific results not provided. |
| Achieve specific accuracy for instrument angular position perpendicular to the system camera measurement. | Tested per ASTM F2554-18. Specific results not provided. |
| Achieve specific accuracy for instrument angular position parallel to the system camera measurement. | Tested per ASTM F2554-18. Specific results not provided. |
| Achieve specific accuracy for distance between points measurement. | Tested per ASTM F2554-18. Specific results not provided. |
| Dimensional similarity to predicate devices. | "A detailed dimensional analysis and one-to-one comparison has been conducted for subject and predicate device to support the substantial equivalence." and "The ASTRA, AVANT and ASTRA-OCT Navigation instruments Systems are dimensionally similar to the cited corresponding predicate devices." |
2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)
This document describes non-clinical performance testing of physical surgical instruments, not a study involving patient data or an AI/ML algorithm's test set. Therefore, information regarding "sample size for the test set" and "data provenance" (country of origin, retrospective/prospective) is not applicable in the context of this 510(k) summary. The testing was laboratory-based.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This is not applicable as the document describes non-clinical performance testing of physical instruments, not an AI/ML algorithm requiring expert ground truth for a test set.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This is not applicable for the reasons stated above.
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
A multi-reader multi-case (MRMC) comparative effectiveness study was not performed as this device is a set of navigated surgical instruments, not an AI/ML assistance system for human readers. No clinical studies were performed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This refers to an AI/ML algorithm. The device described, "ASTRA & AVANT Navigation Instruments System and ASTRA-OCT Navigation Instruments System," is a set of non-sterile, reusable surgical instruments designed for compatibility with a navigation system (Medtronic StealthStation® System S8). It is not a standalone AI/ML algorithm. Non-clinical performance testing was done on the instruments themselves.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the non-clinical performance testing, the "ground truth" would be established by the precise measurement systems and methodologies outlined in ASTM F2554-18 for determining positional accuracy. This is a technical standard measurement, not expert consensus, pathology, or outcomes data typically associated with AI/ML clinical studies.
8. The sample size for the training set
This is not applicable as there is no AI/ML algorithm being trained by this device.
9. How the ground truth for the training set was established
This is not applicable for the reasons stated above.
