Intended Use

The SPINUAT-P is indicated for ablation, and decompression of disc material to treat symptomatic patients with contained herniated discs.

Device Description

The SPINAUT-P is a minimally invasive RF electrode device offered in 496mm length for percutaneous disc decompression surgery using radiofrequency energy and designed for use with radiofrequency generators in RF procedure. SPINAUT-P is intended to be placed into the epidural space or posterolateral / posterocentral area in the disc to remove, ablate or coagulate disc material in the area. The electrode consists of two stainless steel shafts with straight electrode configuration design. The shaft is housed in a coating composed of Polyamide. The device is single-use gamma radiation sterilized and is compatible with most standard electrosurgical generators that provide a cable with two pin outlet (2-pin, 22mm) with 1kVp maximum electrical capacity.

AI/ML Overview

The provided text is a 510(k) summary for the SPINAUT-P device, an electrosurgical device for disc decompression. It details the device's technical specifications and the non-clinical tests performed to demonstrate its substantial equivalence to predicate devices. However, it does not contain any information about a clinical study involving human patients or the performance of a device against specific acceptance criteria in a clinical setting.

The document focuses on non-clinical (bench and lab) testing to support a premarket notification for a medical device. Therefore, I cannot provide details on acceptance criteria and a study that proves the device meets those criteria in a clinical context, or information related to human reader studies.

Here's a breakdown of what can be extracted from the document regarding non-clinical performance and testing:

1. Table of Acceptance Criteria and Reported Device Performance (Non-Clinical)

The document primarily focuses on demonstrating that the SPINAUT-P device meets electrical safety, biocompatibility, sterilization, and some performance characteristics comparable to predicate devices. It lists test descriptions and referenced standards, implying that the acceptance criteria are met by adhering to these standards and the established "pre-set criteria" mentioned.

2. Sample Size Used for the Test Set and Data Provenance

  • Test Set Sample Size: The document mentions tests on "porcine spines" for performance comparison, but does not specify the number of porcine spines or individual tests conducted. For other tests (sterilization, shelf life, biocompatibility, electrical safety), it refers to established standards (e.g., ISO, ASTM, ANSI/AAMI, USP) which dictate sample sizes, but these specific numbers are not presented in the summary.
  • Data Provenance: The data is from non-clinical (bench and lab) testing, not human studies. The tests were performed by or for IMEDICOM Co., Ltd. (Republic of Korea). The specific location of testing labs is not detailed beyond the company's origin.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts

  • This information is not applicable to the non-clinical testing described. Ground truth or expert consensus is typically associated with clinical studies involving human data, where human experts (e.g., radiologists, pathologists) provide annotations or diagnoses.

4. Adjudication Method for the Test Set

  • This information is not applicable as the document describes non-clinical laboratory testing, not a clinical study where adjudication of human expert opinions would be necessary.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

  • No, an MRMC comparative effectiveness study was not conducted. The document focuses on demonstrating substantial equivalence through non-clinical testing, not a clinical trial comparing human readers with and without AI assistance. The device itself is an electrosurgical tool, not an AI diagnostic or assistance system.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

  • No, a standalone algorithm performance study was not conducted. This device is an electrosurgical accessory, not an AI algorithm.

7. Type of Ground Truth Used

  • For the non-clinical performance comparison using porcine spines, the "ground truth" would be the objective measurements and observations of tissue removal, durability, and navigability, compared against the predicate device under controlled experimental conditions.
  • For other tests (electrical, sterility, biocompatibility), the "ground truth" is adherence to the published specifications and pass/fail criteria defined by the referenced international and national standards (e.g., ISO, ASTM, ANSI/AAMI, USP).

8. Sample Size for the Training Set

  • This information is not applicable. The device is an electrosurgical tool, not an AI/ML algorithm that requires a training set.

9. How the Ground Truth for the Training Set Was Established

  • This information is not applicable for the same reason as point 8.
