The AtriCure Dissector™ is intended to dissect soft tissue during general, ENT, thoracic, urological and gynecological surgical procedures. The Dissector's battery-powered light source is used to navigate soft tissue for identification of anatomic structures.
The AtriCure Dissector™ is a hand held, single use, surgical articulated dissector with intearal light source intended to for use by qualified surgeons only. The surgeon is able to articulate the distal member of the device by means of hand actuated rotation knob. The surgeon directly controls the amount of articulation and tissue dissection. A small light source is attached to the distal tip of the articulation member, which remains illuminated for a minimum of four (4) hours. Multiple models of the Dissector™ are available with varving shaft lengths to accommodate surgeon preference and differing patient habitus.
The provided text is a 510(k) Summary for a medical device called the AtriCure Dissector™. It describes the device, its intended use, and claims substantial equivalence to a previously cleared device. However, it does not contain information about specific acceptance criteria, a study proving device performance against those criteria, or details regarding sample size, ground truth, or expert involvement in such a study.
The document does mention:
- "Appropriate product testing was conducted according to the Design Control requirements as defined in 21 CFR 820.30 to evaluate conformance to product specification and substantial equivalence to the legally marketed device."
- "These activities included Risk Analysis, Process Verification, and Biocompatibility Testing."
- "Biocompatibility testing was conducted according to ISO 10993-1 to confirm that the modified Dissector™ is safe for limited use (<24 hrs) as a patient contacting device."
This indicates that internal testing was performed to ensure the device met its design specifications and was biocompatible. However, it does not provide the specific performance acceptance criteria or the results of those tests in a way that can be presented in the requested table format.
Therefore, I cannot fulfill your request to describe the acceptance criteria and the study that proves the device meets them from the provided text. The document focuses on regulatory clearance based on substantial equivalence, not on a detailed performance study with specific acceptance criteria as you've outlined.
Here's a breakdown of why each specific point cannot be addressed from the given text:
- A table of acceptance criteria and the reported device performance: Not provided. The document states "conformance to product specification" but doesn't list the specifications or the performance metrics.
- Sample sized used for the test set and the data provenance: Not provided for performance testing. Biocompatibility testing is mentioned but without sample sizes or provenance details.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Performance testing details are not provided.
- Adjudication method for the test set: Not applicable. Performance testing details are not provided.
- 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: Not applicable. This device is a surgical instrument, not an AI-assisted diagnostic tool.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is a human-operated surgical device.
- The type of ground truth used: Not applicable. Performance testing details are not provided.
- The sample size for the training set: Not applicable. This is a physical device, not an AI/ML algorithm requiring a training set.
- How the ground truth for the training set was established: Not applicable. (See #8).

The AtriCure dissector™ is intended to dissect soft tissue during general, ENT, thoracic, urological and gynecological surgical procedures. The Dissector's battery-powered light source is used to navigate soft tissue for identification of anatomic structures.
The AtriCure dissector™ is a hand held, single use, surgical articulated dissector with integral light source.
The provided text is a 510(k) summary for the AtriCure dissector™, a surgical device. It does not describe a study that proves the device meets specific acceptance criteria in the way an AI/software device submission would. Instead, it focuses on demonstrating substantial equivalence to a predicate device through product testing and material suitability.
Therefore, many of the requested elements for an AI/software device study, such as sample size, expert qualifications, adjudication methods, MRMC studies, standalone performance, and ground truth types, are not applicable or not provided in this document.
However, I can extract the information that is present and indicate where the requested information is not available:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Predicate Device Equivalence | The AtriCure dissector™ is substantially equivalent to the Stryker Knifelight Lighted Knife (K961122). |
| Indications for Use Equivalence | The indications for use are substantially equivalent to the predicate device. |
| Basic Overall Function Equivalence | The basic overall function is substantially equivalent to the predicate device. |
| Material Equivalence | The materials used are substantially equivalent to the predicate device. |
| Biocompatibility | Testing was conducted in accordance with ISO 10993-1 to ensure appropriate biocompatibility of all materials. |
| Conformance to Product Specification | Appropriate product testing was conducted to evaluate conformance to product specification. |
| Substantial Equivalence to Predicate Devices | Appropriate product testing was conducted to evaluate substantial equivalence to predicate devices. |
2. Sample size used for the test set and the data provenance
Not applicable. This is not an AI/software device being evaluated with a test set of data. The "testing" refers to product testing for device function and biocompatibility.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. Ground truth for an AI test set is not relevant for this type of medical device submission.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable.
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
Not applicable. This is not an AI-assisted device for diagnostic interpretation.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical surgical tool.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
Not applicable. Ground truth as typically understood for AI evaluation is not relevant here. The "ground truth" for this device would be its ability to perform its intended mechanical and lighting functions safely and effectively, which is assessed through engineering and biocompatibility testing against predefined specifications and predicate device equivalence.
8. The sample size for the training set
Not applicable. This is not an AI/software device that undergoes a training process.
9. How the ground truth for the training set was established
Not applicable.
