The AP50/30 Insufflator is a CO2 insufflator intended for use during diagnostic and/or therapeutic endoscopic procedures to distend a cavity by filling it with gas. The Standard/High Flow, Pediatric operating modes of the device are indicated to fill and distend a peritoneal cavity with gas during a laparoscopic procedure. The Pediatric operating mode is specifically indicated for pediatric laparoscopic procedures. The Vessel Harvesting mode is indicated for use during endoscopic vessel harvesting procedures to create a cavity along the saphenous vein or radial artery. The TAMIS operating mode is indicated to fill and distend the rectum and colon using CO2 gas during trans and minimal invasive surgery.
The Insuflow® Port (5 mm, 8 mm, 10mm and 12mm) devices have applications in thoracic, abdominal and gynecologic minimally invasive endoscopic surgical procedures to establish a path of entry for endoscopic instruments and to heat, humidify, filter and introduce a CO2 gas stream for insufflation of the surgical cavity.
The Lexion AP50/30 Insufflator is a microprocessor-controlled CO2 (carbon dioxide) insufflator with multiple operating modes. The insufflator instrumentation is intended for hospital use for Standard/High Flow, Pediatric, and Bariatric laparoscopic procedures used in conjunction with a laparoscope to fill and distend a peritoneal cavity with gas; for trans anal minimal invasive surgery (TAMIS) to fill and distend the rectum and colon using CO2 gas; and for Vessel Harvesting procedures used to create a cavity along the saphenous vein and/or the radial artery during an endoscopic vessel harvesting procedure.
The device incorporates the following major components and features: a metal housing, a world power supply, pressure reducers, a venting system, a gas heater control and a touch screen user interface with various settings and display elements. The software operation includes system checks, user interface, setting adjustments, warning/error messages and service info. The device is equipped with a continuous pressure measurement mode that controls the conformity of the actual pressure in the peritoneal or extraperitoneal cavity with the pre-set nominal pressure. The AP50/30 Insufflator is designed with several alarms/warnings to inform the operator in case of an overpressure or other malfunctions. The device is to be used with specially designed singleuse tubing sets, the Insuflow® Port, in order to utilize the full capabilities of continuous pressure measurement and gas heating and humidification. (The insufflator can also accept other tubing sets for gas deliver only.)
The Insuflow® Port (5, 8, 10, 12 mm) devices are gas conditioning/access port devices that attach to the outlet of the AP50/30 Insufflator and are designed to warm and humidify the CO2 gas stream prior to insufflation via an integral path of entry device during minimally invasive surgery. The Insuflow® Port consists of an ethylene oxide sterilized, disposable single use tubing set and a path of entry access port device which contains the pressure sensors, a filter, and gas heater/humidifier. The access port device materials are intended for patient contact of less than 24 hours. The Insuflow® Port is connected to the AP50/30 Insufflator via a plug connector cable, which controls the pressure sensing, gas heating and safety circuits for the system. Regulated CO2 gas from the AP50/30 Insufflator flows into the Insuflow® Port, through the in-line filter, continues along the tubing to enter the path of entry access device that contains the heating element and humidification media, and through the path of entry access device lumen for delivery into the patient's surgical cavity.

2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: The document refers to "comparative bench testing" and "design verification testing." It does not specify a numerical sample size in terms of "units tested" or "number of unique test scenarios." This type of engineering testing typically involves a set number of test runs or units to demonstrate specifications are met across operational ranges and conditions.
- Data Provenance: The testing was "performed to demonstrate that the performance of the proposed AP50/30 Insufflator is substantially equivalent to that of the predicate devices." This implies that the data is prospective data generated from testing of the new device intended for submission. The location of testing is not specified, but it would have been conducted by the manufacturer (Lexion Medical LLC) or a contracted test facility.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- N/A. For a hardware medical device like an insufflator, "ground truth" as it relates to expert consensus on images or clinical outcomes is not applicable. The device's performance is objectively measured against engineering specifications (e.g., flow rate, pressure accuracy, alarm function). Verification and validation testing is conducted by engineers and technicians against established specifications.
4. Adjudication Method for the Test Set
- N/A. Adjudication methods (like 2+1, 3+1) are relevant for subjective assessments, typically in image interpretation or clinical trial endpoints that require expert consensus. For an insufflator, performance is measured against objective, quantifiable engineering specifications.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
- N/A. MRMC studies are specific to evaluating the diagnostic performance of imaging devices or algorithms, usually involving human readers interpreting images. This is a hardware device for surgical procedures (insufflation), not an imaging or diagnostic AI/ML device.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
- N/A. This is not an AI/ML algorithm. The device has software that controls its functions, which was validated ("The software used in the AP50/30 Insufflator was determined to have a major level of concern, and was developed and successfully validated in accordance with the FDA guidance for the Content of Premarket Submissions for Software Contained in Medical Devices," issued May 11, 2005."). This software validation assesses the correct functioning of the control algorithms, which operates autonomously to maintain pressure and flow.
7. The Type of Ground Truth Used
- Engineering Specifications / Predicate Device Performance: The "ground truth" for this device's performance is its ability to meet established engineering specifications (e.g., precise control of gas pressure and flow, accurate alarm triggers) and to perform comparably to its legally marketed predicate devices, particularly for the added TAMIS mode. The performance is quantified through direct physical measurements during bench testing.
8. The Sample Size for the Training Set
- N/A. This is not an AI/ML device; there is no "training set." The software is designed and programmed based on engineering principles and requirements, not trained on data.
9. How the Ground Truth for the Training Set was Established
- N/A. As there is no training set for an AI/ML model, this question is not applicable. The software ground truth is derived from design requirements and engineering specifications documented during the device development process.
In summary, the provided document details the regulatory submission for a hardware medical device with specific performance characteristics. The "acceptance criteria" revolve around demonstrating that the modified device (with a new operating mode) performs comparably to its predicates and meets all relevant safety and performance standards. The "study" proving this involves comprehensive bench testing and software validation against objective engineering specifications. The concepts of AI/ML-specific evaluations (like training sets, data provenance for AI models, MRMC studies, or multi-expert adjudication for diagnostic ground truth) do not apply to this type of device submission.

The provided text describes a 510(k) premarket notification for a medical device, the Lexion AP50/30 Insufflator with Insuflow® Port. This document focuses on demonstrating substantial equivalence to predicate devices rather than proving the device meets specific performance acceptance criteria through a clinical study or standalone algorithm evaluation in the way one would for an AI/ML medical device.
The "acceptance criteria" discussed here are primarily in the context of demonstrating equivalence to a predicate device, focusing on functional specifications and safety standards rather than diagnostic performance metrics (like sensitivity, specificity, AUC) typically found in AI/ML device submissions. There is no mention of an AI/ML component in this device.
Therefore, the requested information elements (1-9) which are typically relevant for AI/ML medical device evaluations (e.g., sample size for test set, number of experts for ground truth, MRMC study, standalone performance, training set details) are not applicable to this 510(k) submission.
However, I can extract the information relevant to how this specific device (a CO2 insufflator) demonstrates its performance and safety, framed within the context of a 510(k) submission:
Demonstrating Performance and Safety for the Lexion AP50/30 Insufflator with Insuflow® Port (Non-AI/ML Device)
The submission focuses on demonstrating substantial equivalence to legally marketed predicate devices, the Stryker/WOM 45L CORE Insufflator and Lexion Insuflow® Synergy™ Ports. The "acceptance criteria" are implied by meeting or having comparable performance to these predicates and adhering to relevant safety standards.
1. A table of acceptance criteria and the reported device performance:
Since this is not an AI/ML device, the "acceptance criteria" are functional specifications and comparative performance to predicates. There isn't a direct "acceptance criterion" table in the AI/ML sense, but rather a comparison table of key performance specifications between the proposed device and its predicate.

Insuflow Synergy™ Port (5 mm) and Insylow® Synergy™ XL Port (8 mm, 10mm and 12mm) have applications in thoracic, abdominal and gynecologic minimally invasive endoscopic surgical procedures to establish a path of entry for endoscopic instruments and to heat, humidify, filter and introduce a CO2 gas stream for insufflation of the surgical cavity.
The Insuflow® Synergy™ and Insuflow® Synergy™ XL Port devices are gas conditioning devices that attach to the outlet port of an insufflator or other regulated CO2 source and are design and humidify the CO2 gas stream prior to insufflation via an integral path of entry device during minimally invasive surgery. The Insuflow® Synergy™ XL Port consist of a sterile, disposable single use device with a filter, heater/humidifier, tubing set, and a path of entry access port device. A reusable control module houses the control and safety circuits for the system.
The Insuflow® Synergy™ and Synergy™ XL Port devices and their modifications involve design changes to existing gas conditioning and path of entry devices used in minimally invasive surgery.
Here's an analysis of the acceptance criteria and study information provided:
Acceptance Criteria and Reported Device Performance
The document does not explicitly state formal acceptance criteria with specific performance metrics. Instead, the "acceptance criteria" are implied by demonstrating that the modified devices perform in accordance with specifications and applicable standards, and are "substantially equivalent" to predicate devices. The performance testing focuses on ensuring that the changes do not negatively impact the established functionalities of the original devices.
Acceptance Criteria (Implied) | Reported Device Performance |
---|---|
Gas Conditioning Functionality (Temperature and Humidity) | The document states: "All of the modified devices utilize the same exact design/parts as the predicates for gas conditioning and sealing. As a result, the existing testing for gas temperature and humidity characterization and seal leak integrity testing previously submitted applies directly to these devices." This implies the modified devices meet the same performance as the predicate devices for gas temperature and humidity. No specific quantifiable metrics are provided in this summary, but it's asserted that prior testing for the predicates covers these aspects. |
Seal Leak Integrity | Similar to gas conditioning, the document states: "All of the modified devices utilize the same exact design/parts as the predicates for gas conditioning and sealing. As a result, the existing testing for gas temperature and humidity characterization and seal leak integrity testing previously submitted applies directly to these devices." This indicates the modified devices maintain the same seal leak integrity as the predicate devices. No specific quantifiable metrics are provided here. |
Flow/Pressure Performance | The document states: "Since the lumen designs were changing, flow/pressure performance and insertion/removal testing were repeated and successfully completed for the modified Insuflow® Synergy™ (5 mm) and Synergy™ XL (8 mm,10 mm and 12 mm) Port dual lumen models." While no specific pass/fail criteria or measurements are provided, the claim is that they were "successfully completed," implying they met the required performance for the new lumen designs. |
Insertion/Removal Performance | The document states: "Since the lumen designs were changing, flow/pressure performance and insertion/removal testing were repeated and successfully completed for the modified Insuflow® Synergy™ (5 mm) and Synergy™ XL (8 mm,10 mm and 12 mm) Port dual lumen models." Similar to flow/pressure, no specific metrics are given, but the successful completion implies the devices perform adequately during insertion and removal, despite the thinner inner lumen wall and smaller overall outer lumen diameter in the dual lumen configuration. |
Overall Safety and Effectiveness | The ultimate conclusion: "Based on a comparison to the predicate devices and information provided, it is the conclusion of LEXION Medical that the modified Insuflow Synergy™ Port (5 mm) and the Insuflow Synergy™ XL Port (8 mm, 10 mm and 12 mm) devices are substantially equivalent to devices already on the market being used for these applications... and present no new concerns about safety and effectiveness." This broad criterion is met by demonstrating equivalence through the aforementioned performance tests and comparison to predicates. No specific metrics are provided for "safety and effectiveness" beyond the functional performance. |
Study Details
The provided text describes a submission for a Special 510(k), which is typically used for modifications to a legally marketed device that do not significantly affect its safety or effectiveness. As such, the "study" is primarily a performance testing regimen to validate the design changes rather than a large-scale clinical trial or comparative effectiveness study.
-
Sample size used for the test set and the data provenance:
- Sample Size: Not explicitly stated as a number of units. The testing was conducted for "the modified Insuflow® Synergy™ (5 mm) and Synergy™ XL (8 mm, 10 mm and 12 mm) Port dual lumen models." This implies that representative samples of each modified size/configuration were tested.
- Data Provenance: The testing was conducted by the manufacturer, LEXION Medical, LLC, as part of their risk analysis and product development. This would be retrospective in the sense that it's laboratory/bench testing performed after the design changes were implemented, but before market introduction of the modified device. The country of origin for the data is not specified, but the submitter is based in St. Paul, MN, USA.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not Applicable. This type of device modification and performance testing (bench testing for flow, pressure, and mechanical integrity) does not typically involve human expert "ground truth" establishment in the way an imaging AI algorithm would. The "ground truth" is defined by engineering specifications and physical measurements.
-
Adjudication method for the test set:
- None. Adjudication methods like 2+1 or 3+1 are used for establishing ground truth in subjective assessments, such as interpreting medical images. For physical device performance testing, objective measurements against engineering specifications are used, removing the need for expert adjudication in this context.
-
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 study is not applicable as this device is a surgical instrument (gas conditioner and port) and not an AI-powered diagnostic or assistive tool for image interpretation.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Partially Yes (in a different context). The device itself is a standalone medical device that performs its function without a human "in the loop" for its primary operation (gas conditioning, port access). It's not an AI algorithm. The performance tests described (flow/pressure, insertion/removal) are standalone tests of the device's physical and functional properties.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The ground truth for the performance testing is based on engineering specifications and measurable physical properties. For example, the "ground truth" for flow/pressure performance would be the required flow rates and pressure tolerances as defined by the device design and relevant industry standards. For insertion/removal, it would relate to acceptable forces, ease of use, and lack of damage.
-
The sample size for the training set:
- Not Applicable. This is not an AI/machine learning device, so there is no "training set."
-
How the ground truth for the training set was established:
- Not Applicable. As there is no training set, there is no ground truth established for it in this context.

Just as the Insuflow® Synergy™ Port, the PneuVIEW® XE VeryClear™ has a dual-lumen or single-lumen path of entry access device 5 mm configuration for surgical instrument manipulation and smoke evacuation.
The provided text describes the PneuVIEW® XE VeryClear™ Gas Evacuation Cannula and its 510(k) summary, aiming to demonstrate its substantial equivalence to predicate devices. However, the document does not contain specific acceptance criteria, detailed study designs, or performance metrics in the format requested.
The sections "Discussion of performance testing" and "Conclusion" broadly state that "Extensive performance testing has been conducted to assure that the PneuVIEW® XE VeryClear™ performs in accordance with its specifications and applicable standards. Flow/pressure performance and seal leak integrity testing were successfully completed. Since the access port device is the same size and configuration as the Insuflow Synergy™ Port 5 mm device, the insertion/removal testing previously submitted is directly applicable. In addition, biocompatibility per ISO 10993-1 was demonstrated."
This summary is insufficient to populate the requested table and answer the specific questions regarding acceptance criteria, sample sizes, expert qualifications, and study methodologies for an AI/device performance evaluation. The document focuses on demonstrating substantial equivalence to existing devices rather than a standalone performance study with quantifiable acceptance criteria against a defined ground truth.
Therefore, many of the requested details cannot be extracted from the provided text.
Here's an attempt to answer based on the limited information and what cannot be answered:
1. Table of Acceptance Criteria and Reported Device Performance:
Acceptance Criteria | Reported Device Performance |
---|---|
Flow/Pressure Performance | Successfully completed (implied to meet specifications/standards) |

Insuflow® Synergy™ XL Port (10mm and 12mm) and Insuflow® Synergy™ XLR Port (10mm and 12mm with endoscopic cannula seal) have applications in thoracic, abdominal and gynecologic minimally invasive endoscopic surgical procedures to establish a path of entry for endoscopic instruments and to heat, humidify, filter and introduce a CO2 gas stream for insufflation of the surgical cavity.
The Insuflow® Synergy™ XL and XLR Port are a gas conditioning device that attaches to the outlet port of an insufflator or other regulated CO2 source and is designed to warm and humidify the CO2 gas stream prior to insufflation via an integral path of entry device during minimally invasive surgery. The Insuflow Synergy™ XL and XLR Port consist of a sterile, disposable single use device with a filter, heater/humidifier, tubing set, and a path of entry access port device. A reusable control module houses the control and safety circuits for the system. The integral path of entry access device in the Insuflow Synergy™ XL and XLR Port is designed and constructed similarly to the Insuflow® Synergy™ Port but comes in larger sizes just as the predicate EndoPath trocar device. The Insuflow® Synergy™ XL Port and the Insuflow® Synergy™ XLR Port have access devices in 10 mm and 12 mm configurations with a single-lumen working channel configuration for conditioned gas delivery. The access device has a working channel with duckbill and tool seals for instrument entry into the surgical cavity and delivers conditioned insufflation gas through the working channel. The Insuflow® Synergy™ XLR Port has an endoscope compatible configuration that has an additional seal at the bottom of the main cannula, which serves as a means to seal off around the endoscope, forcing all gas flow out of the peripheral gas exhaust ports. This minor change is intended to reduce fogging and improve visualization. The obturator for the Insuflow Synergy™ XL and XLR Port has a transparent optical window at the distal end, which when used with an endoscope, provides visibility of individual tissue layers during insertion.
The provided text describes a 510(k) summary for the Insuflow Synergy™ XL and XLR Port devices. This document focuses on demonstrating substantial equivalence to predicate devices rather than providing detailed performance studies with acceptance criteria, sample sizes, expert involvement, or statistical analysis typically associated with AI/ML device evaluations.
Therefore, the requested information, particularly regarding specific acceptance criteria with numerical targets, the study proving the device meets them (including sample size, data provenance, expert qualifications, adjudication, MRMC studies, standalone performance, and ground truth establishment for test and training sets), is not present in the provided text.
The text indicates that "Extensive performance testing has been conducted to assure that the Insuflow® Synergy™ XL and XLR Port perform in accordance with its specifications and applicable standards." and lists the types of tests performed. However, it does not provide the results of these tests in a quantifiable way against pre-defined acceptance criteria, nor does it detail the methodology (sample sizes, expert involvement, ground truth) as would be expected for a diagnostic AI/ML device.
What is provided regarding "performance testing" are general categories of tests:
- Flow/pressure performance
- Gas temperature and humidity characterization
- Insertion/removal testing
- Seal leak integrity testing
- A test to confirm that the cannula seal configuration (for the XLR Port) reduces scope fogging and improves visualization.
Conclusion:
Based on the provided text, it's not possible to generate the requested table of acceptance criteria and reported device performance, nor can we answer the subsequent questions about study specifics (sample size, data provenance, expert details, adjudication, MRMC, standalone performance, ground truth establishment) as these details are not included in this 510(k) summary. This document primarily focuses on establishing substantial equivalence to predicate devices through design description and a high-level summary of testing.

Insuflow® Synergy™ Port has applications in thoracic, abdominal and gynecologic minimally invasive endoscopic surgical procedures to establish a path of entry for endoscopic instruments and to heat, humidify, filter and introduce a CO2 gas stream for insufflation of the surgical cavity.
The Insuflow Synergy™ Port (Dual and Single Lumen) is a gas conditioning device that attaches to the outlet port of an insufflator or other regulated CO2 source and is designed to warm and humidify the CO2 gas stream prior to insufflation via an integral path of entry device during minimally invasive surgery. The Insuflow Synergy™ Port consists of a disposable single use device with a filter, heater/humidifier, tubing set, and a path of entry access port device. A reusable control module houses the control and safety circuits for the svstem. Regulated CO2 gas flows into the Insuflow® Synergy™ Port, through the in-line filter, continues along the tubing to enter the path of entry access device that contains the heating element and humidification media, and through the path of entry access device lumen for delivery into the patient's surgical cavity. The integral path of entry access device is designed and constructed similarly to the predicate trocar device with a sealed instrument access lumen. The Insuflow® Synergy™ Port (Dual and Single Lumen) has a dual-lumen or single-lumen path of entry access device configuration for conditioned gas delivery. Both configurations have a working channel with duckbill and tool seals for instrument entry into the surgical cavity. The single lumen device delivers conditioned insufflation gas through the working channel while the dual lumen configuration has a second outer lumen channel for conditioned gas delivery.
The provided text is a 510(k) summary for the Insuflow® Synergy™ Port, a medical device. This type of document is a premarket notification to the FDA to demonstrate that a device is substantially equivalent to a legally marketed predicate device.
This document focuses on regulatory approval based on demonstrating substantial equivalence to predicate devices, rather than presenting a detailed clinical study demonstrating the device's meeting specific, quantitative acceptance criteria via a performance study with a test set, ground truth and human readers.
Therefore, I cannot fully complete all sections of your request as the information is not present in the provided text. However, I can extract what is available.
Description of the Acceptance Criteria and the Study that Proves the Device Meets the Acceptance Criteria:
The Insuflow® Synergy™ Port is a gas conditioning insufflator accessory device designed to warm, humidify, and filter CO2 gas for insufflation during minimally invasive surgeries, and to establish a path of entry for endoscopic instruments. The regulatory pathway for this device was a 510(k) premarket notification, which demonstrates substantial equivalence to predicate devices rather than a direct clinical performance study with specific acceptance criteria in the format you've requested.
The "acceptance criteria" in this context are implicitly related to demonstrating that the Insuflow® Synergy™ Port performs safely and effectively in a manner substantially equivalent to its predicate devices. The study proving this involved extensive performance testing and biocompatibility testing.
1. Table of Acceptance Criteria and Reported Device Performance
As specific quantitative "acceptance criteria" for a clinical performance study (e.g., sensitivity, specificity thresholds) are not explicitly stated in this 510(k) summary, I can only infer what was tested and that the device "successfully completed" these tests, implying they met internal or standard-based criteria.
Acceptance Criteria (Inferred from testing) | Reported Device Performance (Summary) |
---|---|
Flow/Pressure Performance | Successfully completed |
Gas Temperature Characterization | Successfully completed |
Humidity Characterization | Successfully completed |
Insertion/Removal Testing | Successfully completed |
Seal Leak Integrity Testing | Successfully completed |
Biocompatibility (ISO 10993-1) | Successfully conducted |
2. Sample Size Used for the Test Set and Data Provenance
This information is not provided in the summary. The document mentions "extensive performance testing" but does not detail the sample sizes for these tests or the provenance of any data (e.g., country of origin, retrospective/prospective). It is likely these were bench/laboratory tests rather than tests on patient data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided. Given the nature of the device (a gas conditioning insufflator and access port) and the type of testing described (flow/pressure, temperature, humidity, insertion/removal, seal leak, biocompatibility), it's highly improbable that "experts to establish ground truth" in the context of diagnostic performance (e.g., radiologists interpreting images) would be relevant or used. The "ground truth" for the performance tests would be instrument measurements and standardized test procedures.
4. Adjudication Method for the Test Set
This information is not provided and is not applicable for the type of testing described in this 510(k) summary. Adjudication methods like "2+1" or "3+1" are typically used in studies involving human interpretation of data where consensus is needed for ground truth (e.g., image interpretation).
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and the effect size of how much human readers improve with AI vs without AI assistance
No, a MRMC comparative effectiveness study was not performed. This device is a surgical instrument accessory, not an AI-powered diagnostic tool, so such a study would not be applicable or relevant to its regulatory approval.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
This question is not applicable. The Insuflow® Synergy™ Port is a physical medical device, not an algorithm, so a "standalone" algorithmic performance study without human-in-the-loop would not be relevant.
7. The Type of Ground Truth Used
For the performance tests mentioned (Flow/Pressure, Gas Temperature, Humidity, Insertion/Removal, Seal Leak Integrity), the "ground truth" would be established by objective physical measurements using calibrated instruments and adherence to established engineering and medical device standards. For biocompatibility, it would be established by laboratory testing results against ISO 10993-1. Pathology or outcomes data would not directly serve as ground truth for these types of tests.
8. The Sample Size for the Training Set
This information is not provided and is not applicable. The device is a physical hardware product, not a software algorithm that requires a "training set."
9. How the Ground Truth for the Training Set Was Established
This information is not provided and is not applicable for the reasons stated in point 8.

The Vessel Guardian® device is a single use device that attaches to the outlet port of an insufflator or other regulated CO2 source and is designed to warm and humidify the CO2 gas stream prior to insufflation into the surgical cavity. The Vessel Guardian® device consists of a disposable filter heater/humidifier tubing set and a control module that houses the control and safety circuits for the system. Regulated CO2 gas flows into the Vessel Guardian® device, through the in-line filter, continues along the tube to enter the Vessel Guardian® device cassette that contains the heating element and humidification media, through a tube that connects via a Luer lock connector to a gas entrance port or an insufflation needle/trocar and finally flows into the patient's surgical cavity.
The provided text describes a 510(k) premarket notification for the "Vessel Guardian®" device, a laparoscopic insufflator gas conditioner. Instead of presenting a detailed study, the submission relies on the concept of "substantial equivalence" to predicate devices already on the market. Therefore, the information typically found in a study demonstrating device performance against acceptance criteria is not present in this document.
Here's an analysis based on the provided text, outlining why certain sections of your request cannot be fulfilled and what information is available:
1. A table of acceptance criteria and the reported device performance
This information is not provided in the document. The submission states: "Extensive performance testing has been conducted to assure that the Vessel Guardian® (i.e., Insuflow ) performs in accordance with its specifications and applicable standards."

Summary of Available Information from the Document:
The core argument for the Vessel Guardian®'s safety and effectiveness is its substantial equivalence to predicate devices.
-
Predicate Devices:
-
Claim of Equivalence: "Technically, the Vessel Guardian® is identical to the VasoVapor™ and Insuflow devices cleared for market in 510(k) K101320 and K090456, respectively. The indications for use for the Vessel Guardian® are patterned after the predicate devices, being specific to the endoscopic vessel harvesting application."
-
Performance Testing (General Statement): "Extensive performance testing has been conducted to assure that the Vessel Guardian® (i.e., Insuflow ) performs in accordance with its specifications and applicable standards." However, the details of this testing, including specific acceptance criteria and results, are not included in the provided summary. The FDA's letter confirms that they "reviewed your Section 510(k) premarket notification... and have determined the device is substantially equivalent." This means the FDA found sufficient evidence in the full submission to support the claim of equivalence, which would include the performance testing mentioned, even if not detailed in this summary.
In conclusion, this document is a 510(k) summary focused on demonstrating substantial equivalence, not a detailed clinical study report. Therefore, most of the specific data points requested regarding acceptance criteria, sample sizes, expert involvement, and ground truth establishment are not present in this public summary.

VasoVapor™ is a gas conditioner accessory device for use in endoscopic vessel harvesting surgical procedures, intended to heat, humidify and filter a CO2 gas stream for insufflation of the surgical cavity.
The VasoVapor™ device is a single use device that attaches to the outlet port of an insufflator or other regulated CO2 source and is designed to warm and humidify the CO2 gas stream prior to insufflation into the surgical cavity. The Vaso Vapor™ device consists of a disposable filter heater/humidifier tubing set and a control module that houses the control and safety circuits for the system. Regulated CO2 gas flows into the VasoVapor™ device, through the in-line filter, continues along the tube to enter the VasoVapor™ device cassette that contains the heating element and humidification media, through a tube that connects via a Luer lock connector to a gas entrance port or an insufflation needle/trocar and finally flows into the patient's surgical cavity.
This document is a 510(k) premarket notification for the LEXION Medical VasoVapor™ device, a laparoscopic insufflator gas conditioner. It claims substantial equivalence to previously cleared devices (Insuflow®, K063546 and K090456).
1. A table of acceptance criteria and the reported device performance
The document does not provide a table of acceptance criteria and reported device performance for the VasoVapor™ in this submission. Instead, it states that "Extensive performance testing has been conducted to assure that the VasoVapor™ (i.e., Insuflow®) performs in accordance with its specifications and applicable standards. Details of that testing were provided in 510(k) K063546 and K090456 are referenced in Section 5 for completeness."
Therefore, the performance data for VasoVapor™ is referred to previous 510(k) submissions, and is not detailed in this specific document.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not provide information on the sample size used for a test set or data provenance for VasoVapor™. It refers to prior 510(k) submissions (K063546 and K090456) for details on performance testing.
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)
The document does not provide information about experts used to establish ground truth or their qualifications. The device is a gas conditioner accessory, and its performance would likely be assessed through physical and engineering tests rather than expert interpretation of medical images or data.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
The document does not describe any adjudication method. This type of method is generally applicable for studies involving human interpretation (e.g., medical imaging) to resolve disagreements, which is not relevant for a device like a gas conditioner.
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
A multi-reader multi-case (MRMC) comparative effectiveness study was not done. This type of study is typically used for diagnostic or screening devices where human readers interpret medical data, often with or without AI assistance. The VasoVapor™ is an accessory device; not a diagnostic or screening tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
A standalone performance evaluation (algorithm only) was not done, as the VasoVapor™ is a hardware device for conditioning gas, not an algorithm. Its performance would be measured by physical parameters (e.g., temperature, humidity, flow rate) rather than algorithm accuracy.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The document does not explicitly state the type of ground truth used. For a gas conditioning device, "ground truth" would likely refer to objective measurements of physical parameters such as temperature, humidity, and filtration efficacy, against established engineering specifications and standards.
8. The sample size for the training set
The document does not mention a training set sample size. A training set is typically relevant for machine learning algorithms, which are not applicable to the VasoVapor™ device.
9. How the ground truth for the training set was established
The document does not mention a training set or how its ground truth was established, as it is not an AI/ML device.
