Intended Use

The ARTAS™ System from Restoration Robotics is indicated for harvesting hair follicles from the scalp in men diagnosed with androgenic alopecia (male pattern hair loss) who have black or brown straight hair. The ARTAS System from Restoration Robotics is intended to assist physicians in identifying and extracting hair follicular units from the scalp during hair transplantation.

Device Description

The ARTAS System implements the manual Follicular Unit Extraction (FUE) approach to harvesting follicular units. The ARTAS System is used, under the direction of a physician, to automate the manual FUE technique. The ARTAS System is positioned over the patient's scalp by the physician. Follicular units are then identified, dissected and extracted from the surrounding tissue on the patient's scalp by the ARTAS System. The follicular units are transported using suction to a storage container where they are stored until they are implanted into the patient's scalp by the physician or technician using current manual implantation techniques. The ARTAS System is an interactive, image-guided, computer-assisted system consisting of seven main subsystems: 1. Robotic Arm Subsystem 2. Imaging Subsystem 3. Needle Mechanism 4. Safety Subsystem 5. Computer 6. Accessory Kits (Disposable and Reusable) 7. Patient Chair These main subsystems, with the exception of the Accessory Kits and Patient Chair, are housed on or within a Control Cart.

AI/ML Overview

Here's a summary of the acceptance criteria and the study details for the ARTAS™ System.

1. Table of Acceptance Criteria and Reported Device Performance

The provided document describes the primary effectiveness endpoint as the difference in the number of surviving implanted hair follicles at Month 9 post-implantation between those harvested using the ARTAS System and those harvested manually. The acceptance criteria essentially were to demonstrate substantial equivalence to the manual method.

Acceptance CriteriaReported Device Performance
Substantially equivalent (in terms of safety and effectiveness) to predicate devices, specifically the manual FUE method for hair follicle harvesting.The ARTAS System was found to be substantially equivalent to the manual harvest method in terms of the number of surviving implanted hair follicles at nine months (p = 0.023). No new issues of safety or effectiveness were raised.
No new safety issues (adverse events, serious adverse events, unanticipated adverse events) compared to the manual procedure.No adverse events, serious adverse events, or unanticipated adverse events were reported. All complications were "Mild" in intensity. Subjects did not terminate the study early due to safety-related issues.

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

  • Sample Size for Test Set: 36 subjects.
  • Data Provenance: Prospective, multi-center clinical study conducted at two U.S. clinical sites.

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

The document does not explicitly state the number of experts used to establish the ground truth for the test set or their specific qualifications (e.g., dermatologists, plastic surgeons, specific years of experience). However, it mentions that the study was conducted under the direction of a physician and involved clinical sites. The intended use states the system is "intended to assist physicians," implying physician involvement in the assessment of outcomes.

4. Adjudication Method for the Test Set

The document does not specify an adjudication method like 2+1 or 3+1. Given the nature of the primary endpoint (number of surviving implanted hair follicles), it's likely that a clinical assessment was performed, but the details of who performed this assessment and how disagreements (if any) were resolved are not provided.

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

The study was a multi-center, prospective, blinded clinical study comparing the ARTAS System (AI-assisted) to the manual hair follicle harvesting method. It was a comparative effectiveness study in that it compared the outcomes of two different methods. However, it was not a typical MRMC study evaluating human readers' performance improvement with AI assistance on diagnostic tasks. Instead, it evaluated the clinical outcome (surviving hair follicles) of an AI-assisted surgical procedure versus a manual surgical procedure. Therefore, an "effect size of how much human readers improve with AI vs without AI assistance" in the traditional sense of diagnostic accuracy is not reported or applicable to this study design.

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

The ARTAS System is described as an "interactive, image-guided, computer-assisted system" that "assists physicians in identifying and extracting hair follicular units." The study directly compares the system's performance (when used under physician direction) against the manual method. While the system automates parts of the FUE technique, it is used "under the direction of a physician." Therefore, the clinical study assessed the system's performance with a human-in-the-loop, not in a standalone (algorithm only) capacity, as it requires physician oversight and manual implantation.

7. The Type of Ground Truth Used

The ground truth for the primary effectiveness endpoint was outcomes data: "the number of surviving implanted hair follicles at Month 9 post-implantation." This is a direct clinical outcome measure.

8. The Sample Size for the Training Set

The document does not provide information on the sample size used for the training set for the ARTAS System's AI components. The clinical study details describe the test set used for regulatory submission.

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

The document does not provide information on how the ground truth for the training set was established.

SUBSTANTIAL EQUIVALENCE

The proposed indications for use for the ARTAS System is substantially equivalent to the indications for use of the Medicamat S.A. Calvitron Hair Transplant System. Any differences in the technological characteristics between the devices do not raise any new issues of safety or effectiveness. Thus, the ARTAS System is substantially equivalent to the predicate devices.

TESTING IN SUPPORT OF SUBSTANTIAL EQUIVALENCE DETERMINATION

All necessary functional and clinical testing was conducted on the ARTAS System to support a determination of substantial equivalence to the predicate devices.

SECTION 5
510(K) SUMMARY (CONT.)

Nonclinical Testing Summary:

The nonclinical, bench testing included:

  • Electrical Safety and Electromagnetic Compatibility Testing .
  • Software Verification and Validation Testing .
  • Hardware Design Verification Testing .
  • � Cytotoxicity Testing

The collective results of the nonclinical testing demonstrate that the materials chosen, the manufacturing processes, and design of the ARTAS System meet the established specifications necessary for consistent performance during its intended use. In addition, the collective bench testing demonstrates that the ARTAS System does not raise new questions of safety or effectiveness for follicular unit extraction when compared to the manual procedure.

Clinical Testing Summary:

A multi-center, prospective, blinded, clinical study was performed to compare the safety and effectiveness of the ARTAS System to the manual hair follicle harvesting method following a nine month period of post-procedural evaluation. The clinical study enrolled healthy men, between the ages of 30 and 59, who had brown or black straight hair and a clinical diagnosis of androgenetic alopecia (male pattern hair loss).

A total of 36 subjects were treated in this study at two U.S. clinical sites. The mean age of the participants was 48.6 ± 7.5. Subjects predominantly had black hair and stage V or VI baldness on the Norwood-Hamilton Classification scale. The population at both sites was similar.

There were no adverse events, serious adverse events or unanticipated adverse events reported by any subjects during the course of this study. All complications were "Mild" in intensity. None of the subjects terminated the study early due to any safety-related issues.

The primary effectiveness endpoint was the difference in the number of surviving implanted hair follicles at Month 9 post-implantation between those implanted hair follicles that were harvested using the ARTAS System and those that were harvested using the manual method of hair harvest. In comparing the implant results by hair follicle harvest method, the ARTAS System was found to be substantially equivalent to the manual harvest method at nine months (p = 0.023). The primary effectiveness endpoint of this study was achieved.
