The ArthroCare ArthroWands are bipolar, single use, high frequency electrosurgical devices designed for specific indications in arthroscopic and orthopedic procedures.
This is a 510(k) premarket notification for electrosurgical devices (ArthroCare® ArthroWands®). The document states that the proposed modifications are not substantial changes or modifications, and do not significantly affect the safety or efficacy of the devices; therefore, no new studies were conducted. The device is found to be substantially equivalent to previously cleared predicate devices (K020557 and K033584).
Here's an analysis based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
No specific acceptance criteria or performance metrics derived from new testing are provided in this special 510(k). The basis for clearance is substantial equivalence to predicate devices. The document explicitly states: "The proposed modifications in the performance specifications, labeling, and packaging configuration are not substantial changes or modifications, and do not significantly affect the safety or efficacy of the devices."
Therefore, the "acceptance criteria" here is that the modified device's performance remains consistent with, and not significantly worse than, the predicate devices cleared under K020557 and K033584, for which presumably performance data would have been submitted at that time.
| Acceptance Criteria (Implied) | Reported Device Performance (Implied by Substantial Equivalence) |
|---|---|
| Performance specifications not significantly altered | Performance is consistent with predicate devices |
| Safety not significantly affected | Safety profile is consistent with predicate devices |
| Efficacy not significantly affected | Efficacy is consistent with predicate devices |
| Indications for Use remain the same | Indications for Use are identical to predicate devices |
| Technology remains the same | Technology is identical to predicate devices |
| Principle of operation remains the same | Principle of operation is identical to predicate devices |
| Sterilization parameters remain the same | Sterilization parameters are identical to predicate devices |
2. Sample Size Used for the Test Set and Data Provenance
No new test set was used for a study comparing the modified device's performance directly. This submission relies on the established performance of its predicate devices.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
Not applicable, as no new clinical or performance test set was evaluated.
4. Adjudication Method for the Test Set
Not applicable, as no new test set was evaluated.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No. This document does not mention any MRMC study. The device is an electrosurgical tool, which typically undergoes performance testing (e.g., power output, tissue effects) rather than MRMC studies.
6. Standalone Performance Study (Algorithm Only)
No. This is a physical electrosurgical device, not an AI algorithm.
7. Type of Ground Truth Used
Not applicable, as no new performance claims, clinical data, or "ground truth" establishment are presented for the modified device beyond its substantial equivalence to predicates.
8. Sample Size for the Training Set
Not applicable, as this is not an AI/machine learning device.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as this is not an AI/machine learning device.
