The AtriClip LAA Exclusion System is indicated for the occlusion of the heart's left atrial appendage, performed under direct visualization and in conjunction with other cardiac surgical procedures.
Direct visualization, in this context, requires that the surgeon is able to see the heart directly, with or without assistance from a camera, endoscope, etc., or other appropriate viewing technologies.
The AtriClip LAA Exclusion System consists of a single use, sterile, self-closing, implantable Clip preloaded on a Single Use Clip Applier along with a selection guide. When closed, the Clip applies uniform pressure over the length of the Clip to ensure consistent, reproducible, and secure occlusion of the left atrial appendage (LAA). The clip is then deployed and is left as a permanent implant. The Clip is available in the following lengths to accommodate different sizes of LAA: 35 mm, 40 mm, 45 mm, and 50 mm.
The Clip Appliers are disposable devices with a handle, shaft, suture anchors, and deployment end-effector containing the Clip.
Here's a breakdown of the acceptance criteria and study information for the AtriClip LAA Exclusion System based on the provided document:
Acceptance Criteria and Device Performance
The document does not explicitly state formal "acceptance criteria" as a pass/fail threshold. Instead, it presents performance results from clinical studies and a published literature review, which serve as evidence of the device's safety and effectiveness. The "reported device performance" in the table below is derived from these stated clinical outcomes.
| Metric | Acceptance Criteria (Implied) | Reported Device Performance (Clinical Evidence) |
|---|---|---|
| LAA occlusion directly following Clip deployment | High percentage occlusion | 99% (128/129 patients) |
| LAA exclusion post-operatively (3-12 months) | High percentage exclusion | 96% (56/58 patients) |
| Device-related serious adverse events | Zero adverse events | Zero (0) |
Study Information
The information provided describes a combination of clinical study data and a published literature review.
2. Sample size used for the test set and the data provenance:
- Total Patients Evaluated (Clinical Evidence): 129 patients
- LAA occlusion directly following Clip deployment: 129 patients
- LAA exclusion post-operatively (3-12 months): 58 patients
- Data Provenance: The document emphasizes "clinical evidence based on the multiple IDE clinical studies and published clinical literature." This suggests a combination of prospective data from AtriCure-sponsored IDE studies (e.g., IDE Stroke, Hybrid DEEP, Staged DEEP) and data from retrospective or prospective studies included in the literature review. The country of origin is not specified but is implicitly the US for the IDE studies.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the document. The studies refer to "LAA occlusion" and "LAA exclusion" as outcomes, but do not specify how these were determined (e.g., by human experts, imaging interpretation, etc.) nor the qualifications of those involved in assessing these outcomes.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- This information is not provided in the document.
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:
- No, an MRMC comparative effectiveness study was not done. The device being reviewed is an implantable clip, not an AI-powered diagnostic or assistive tool for human readers. Therefore, the concept of "human readers improve with AI vs without AI assistance" is not applicable.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. The AtriClip LAA Exclusion System is a medical device (an implantable clip and applier), not an algorithm or AI system. Its performance is evaluated through its physical function in occluding the LAA in vivo.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The ground truth appears to be based on clinical outcomes data from the clinical studies. For "LAA occlusion directly following Clip deployment," this would likely be immediate intraoperative assessment (visual or imaging). For "LAA exclusion post-operatively," this would typically involve follow-up imaging (e.g., transesophageal echocardiography) to confirm the complete closure or exclusion of the LAA.
8. The sample size for the training set:
- This information is not applicable/not provided as the device is not an AI/ML model that requires a training set in the conventional sense. The "training" for such a device would be its design, manufacturing, and preclinical testing phases.
9. How the ground truth for the training set was established:
- This information is not applicable/not provided for the same reason as above.

Clinical Studies
AtriCure has collected scientific based evidence from multiple sponsored IDE clinical studies on the use of the AtriClip LAA Exclusion System during video assisted thoracoscopic procedures of the left atrial appendage (LAA). In the IDE Stroke clinical study (G110145) patients were implanted with the AtriClip device via video assisted thoracoscopic procedures without any adverse events. At three months followup, these patients had 100% LAA exclusion.
In addition, AtriCure also conducted two IDE studies, Hybrid DEEP (G090279) and Staged DEEP (G120056), where the AtriClip devices were implanted via using video without any adverse events.
{5}------------------------------------------------
Furthermore, AtriCure performed a published literature review evaluating the use of AtriClip LAA Exclusion System devices, which provided additional evidence the device can be placed safely at the base of the appendage via a video assisted thoracoscopic procedure of the LAA.
In totality of the clinical evidence based on the multiple IDE clinical studies and published clinical literature, 129 total patients were safely implanted during video assisted thoracoscopic procedures of the left atrial appendage.
A review of the IDE clinical studies and published literature evaluated the following endpoints when the Clip was deployed via a video assisted thoracoscopic procedures of the LAA: 1.) LAA occlusion directly following Clip deployment and 2.) LAA exclusion post-operatively. The results demonstrated: 1.) 99% (128/129) of the patients had LAA occlusion directly following Clip deployment and 2.) 96% (56/58) of patients had LAA exclusion evaluated at 3-12months post-operatively.
The IDE EXCLUDE clinical study, included in the original AtriClip 510(k) premarket notification - K093679, demonstrated effectiveness of 95.7% LAA occlusion directly following Clip deployment and 98.4% LAA exclusion 3 months post-operatively.
There were Zero (0) AtriClip device related serious adverse events reported in the clinical studies and published literature.
Summary
Based on the clinical performance as documented in the clinical studies and published literature, the AtriClip LAA Exclusion System was found to have a safety and effectiveness profile similar to the predicate device. Substantial equivalence was based in part on this information.
VIII. Conclusions
The AtriCure sponsored clinical studies, published literature, and bench testing data included in this submission provide evidence demonstrating the AtriClip LAA Exclusion System, as labeled per the Indication for Use, provide A.) clinically significant results and at the same time B.) do not present an unreasonable risk of illness or injury associated with the use of the device.
