The VersaOne™ optical trocar with fixation balloon cannula is indicated for use in general, gynecologic, thoracic and urologic minimally invasive surgical procedures.

The intended purpose of the device is to create and maintain a port of entry. The trocar may be used with or without visualization for primary and secondary insertions.

VersaOne™ optical trocar with fixation balloon cannula with a low-profile design is a 5mm diameter transparent fixation cannula in various lengths and is comprised of three components: obturator with optical tip, seal system, and cannula assembly. The obturator is bladeless and has a transparent 'dolphin nose' window at distal end. The obturator housing contains a scope retention mechanism. The cannula assembly is composed of a seal system, trocar housing, transparent cannula sleeve, thermoplastic elastomer (not made with natural rubber latex) balloon, anti-migration disc and a stopcock. The seal system prevents the loss of pneumoperitoneum and can accommodate instruments 5mm in diameter. The cannula sleeve is beveled and a thermoplastic elastomer (not made with natural rubber latex) balloon is attached at the distal end. The stopcock valve is for insufflation and desufflation of the abdominal cavity. The thermoplastic elastomer (not made with natural rubber latex) balloon provides fixation (defined as force that resists the cannula from being inadvertently removed out of the patient). The anti-migration disc is on the proximal end of the cannula body and provides anchoring (defined as the force that resist the cannula from being inadvertently pushed into the patient). The devices are supplied sterile f o r single use. VersaOne™ optical trocar with fixation balloon cannula is packaged with a 5 mL syringe for inflation/deflation of the thermoplastic elastomer (not made with natural rubber latex) balloon. The thermoplastic elastomer (not made with natural rubber latex) balloon is packaged with a protective cap which is removed and discarded before device use.

The provided text describes a 510(k) premarket notification for a medical device, the VersaOne™ optical trocar with fixation balloon cannula. This type of submission relies on demonstrating substantial equivalence to a legally marketed predicate device, rather than requiring extensive clinical trials to prove safety and effectiveness from scratch. Therefore, the information provided mainly focuses on non-clinical performance data (bench testing and animal testing) rather than a detailed human-in-the-loop study often seen with AI/software as a medical device.

Based on the provided document, here's a breakdown of the acceptance criteria and the "study" (non-clinical testing) that proves the device meets them:

The "acceptance criteria" for a 510(k) device like this are primarily demonstrated by showing that its performance characteristics are comparable to a predicate device, and that any new features (like the balloon fixation) do not raise new questions of safety or effectiveness. The "studies" here are the non-clinical tests.

1. A table of acceptance criteria and the reported device performance:

The document doesn't present a formal table of "acceptance criteria" with quantitative targets and reported performance values in the way one might see for an AI algorithm's diagnostic accuracy. Instead, the acceptance is implicitly based on the device meeting design specifications and performing comparably to predicates in various non-clinical tests.

However, we can infer some key performance aspects tested and the general conclusion:

2. Sample size used for the test set and the data provenance:

• Test Set Sample Size: The document does not specify exact sample sizes for each non-clinical test (e.g., number of devices tested for burst force, number of animals used). It simply states that "Testing... performed" or "Animal testing... performed." For a 510(k) of this nature, detailed sample sizes for specific engineering tests would be in the full submission, not typically summarized in the public 510(k) decision letter.
• Data Provenance: The document does not explicitly state the country of origin for the data or if the tests were retrospective or prospective. Given that this is non-clinical testing (bench and animal), the terms "retrospective" or "prospective" don't apply in the same way they would for human clinical data. The tests were presumably conducted as part of the device development and submission process.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

This question is not applicable in the context of this device's 510(k) submission. "Ground truth" established by experts is typically for diagnostic imaging devices where human expert interpretation is the standard against which an algorithm or new diagnostic method is compared. For a surgical trocar, ground truth is established by physical measurement (e.g., force testing), engineering analysis, and direct observation during performance testing (e.g., in animal models). The document mentions "side-by-side" animal testing, which implies comparative observation by individuals conducting the tests, but not "expert consensus" on diagnostic findings.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

Not applicable. Adjudication methods are relevant for human reader studies or clinical trials where discordant findings among human readers or clinical outcomes need to be resolved to establish a definitive "truth" for comparison. For bench and animal testing of a surgical instrument, results are typically objective measurements or direct observations without requiring such adjudication.

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. An MRMC study is a type of clinical comparative effectiveness study, usually for diagnostic devices, particularly those involving human interpretation (e.g., radiologists reading images with or without AI assistance). This 510(k) is for a physical surgical instrument and explicitly states: "Clinical performance data - No clinical study has been performed."

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

Not applicable. This is not an AI/algorithm device. The performance tests ("bench testing" and "animal testing") are for the physical device itself.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

The "ground truth" for this device's performance is established through:

• Engineered Specifications and Physical Measurements: For bench testing (e.g., anchor mechanism force, leak rate, burst force). The device performs to its design specifications.
• Direct Observation and Functional Assessment in Animal Models: For animal testing (e.g., cavity access, tissue visualization, ability to establish/maintain pneumoperitoneum, instrument manipulation). Performance is considered "successful" if it meets the functional needs for a surgical trocar.
• Comparison to Predicate Devices: The ultimate "ground truth" for a 510(k) is demonstrating "substantial equivalence" to a legally marketed predicate device, meaning it performs similarly and does not raise new safety or effectiveness concerns.

8. The sample size for the training set:

Not applicable. This is not an AI/machine learning device that requires a "training set."

9. How the ground truth for the training set was established:

Not applicable. (See #8)

The GelPort Blunt Tip Trocar System is indicated for use in general, abdominal, gynecological and thoracic minimally invasive surgical procedures to establish a path of entry or to gain access through tissue planes, extraperitoneal spaces and/or potential spaces for endoscopic instruments.

The GelPort Blunt Tip Trocar System is a sterile single use device, intended for use in conjunction with Applied's currently marketed Trocar products. A standard trocar assembly consists of an obturator, a seal and a cannula system.

The provided text is a 510(k) summary for a medical device (GelPort Blunt Tip Trocar System) and related FDA correspondence. It does not contain information about acceptance criteria, device performance metrics, or study details (like sample sizes, ground truth establishment, expert qualifications, or MRMC studies) for demonstrating the device meets performance criteria.

Instead, this document focuses on demonstrating substantial equivalence to a predicate device based on performance and functional testing. The key statement is:

"The performance and functional testing of the GelPort Blunt Tip Trocar System compared to its predicate device demonstrated that the GelPort Blunt Tip Trocar System is substantially equivalent to its predicate device and it introduces no new safety and effectiveness issues when used as instructed."

This implies that the device was tested to ensure it functions similarly to the predicate device, but the specific acceptance criteria and results of these tests are not detailed in this summary. The FDA's 510(k) clearance process often relies on demonstrating equivalence rather than establishing new performance benchmarks with clinical studies, especially for devices like trocars.

Therefore, I cannot provide the requested information from the given text.

To answer your prompt, I would need a document that specifically outlines the performance study, its methodology, and its results against predefined acceptance criteria.

The Origin Multi-Port Cannula has applications in minimally invasive surgery to provide a port of access during endoscopic procedures.

The predicate device (Endoscopic Visualization and Space Maintenance Cannula ) has applications in minimally invasive surgery and is primarily indicated for patients undergoing endoscopic surgery including laparoscopy and thoracoscopy.

The Multi-Port Cannula is not intended for use except as indicated. In addition, it is not intended for use when endoscopic surgery is contraindicated.

The Multi-Port Cannula is a single- use device which consists of two movable working cannulas, seals, a stabilizer, two stationary cannulas, leur fitting, and an insufflation tube. The two movable working cannulas passes completely through the stationary cannulas which are casted to the stabilizer. The seals within the inner wall of the cannulas seal on surgical devices that are inserted through the cannulas. The stabilizer provides a seal against the tissue at the incision site and acts to stabilize the cannulas. Surgical access is achieved via standard incision. The Multi-Port Cannula is assembled and advanced through the incision site. The user may then advance endoscopic tools through the working cannulas or stationary cannulas to perform the procedure. The Origin Multi-Port Cannula has applications in minimally invasive surgery to provide a port of access during endoscopic procedures.
