Intended Use

The Nebulae™ I 50 LPM Insufflator provides CO2 gas distention of surgical cavities for diagnostic and/or operative endoscopy. The insufflator has multiple operating modes which can be used for the following procedures: General Laparoscopic Pediatric Laparoscopic Bariatric Laparoscopic Minimally Invasive Vessel Harvesting

Device Story

Microprocessor-controlled CO2 insufflator; provides high-flow gas distention for surgical cavities. Inputs: CO2 gas source (wall or bottle); user-defined settings via touchscreen. Operation: System monitors abdominal pressure via True Abdominal Pressure Sensing (TAP™); regulates flow up to 50 LPM; maintains preset pressure; relieves overpressure conditions (5mmHg above preset) within 3 seconds. Output: Controlled CO2 flow to surgical site; visual status on touchscreen; RS232 data interface. Used in OR by surgeons/clinical staff. Benefits: Enables visualization and access during minimally invasive procedures; maintains stable pneumoperitoneum; supports pediatric and bariatric patient populations through specific operating modes.

Clinical Evidence

Bench testing only. Evaluated flow rates, fill times, flow accuracy, and overpressure relief across all operating modes using abdominal simulators. Comparative testing against predicates confirmed equivalent performance in pediatric modes and flow rates. Tissue desiccation testing on bovine liver showed negligible tissue impact, identical to predicate performance. Electrical safety and EMC testing confirmed compliance with IEC 60601-1 and EN 60601-1-2.

Technological Characteristics

Microprocessor-controlled CO2 insufflator; 50 LPM max flow; touchscreen interface; RS232 connectivity. Features True Abdominal Pressure Sensing (TAP™). Power: 100/115/230 VAC. Compatible with external gas warmers. Tested to IEC 60601-1:2005 (Electrical Safety) and EN 60601-1-2:2007 (EMC).

Indications for Use

#### 6. Technological Differences

The Nebulae™ I device is like the 40L Abdominal Insufflator (K022052) except it flows 50LPM out of a single output port, has a touchscreen, and has one warmer port.

The Nebulae™ I device is like the 45L CORE Insufflator F114 (K063367) except it flows 5LPM more, has Custom Mode, and does not contain a proprietary connection for a tubing set.

# 7. Performance Data

Both Design Verification and Design Validation have been completed.

Performance testing was completed to demonstrate that the Nebulae™ I functions as intended and performs as intended for safety purposes.

Device Flow Rates- Bench testing was done in a simulated use environment for all operating modes and the device performed within the specified flow rates.

Fill Time - Bench testing was done in a simulated use environment and proved that the Nebulae I could fill an abdomen simulator within the specified time period.

Flow Accuracy - Bench testing was done to prove that the Nebulae™ I could maintain specified flow accuracy for the flow rates in all modes and the device performed within the specified flow accuracy range.

Overpressure Relief - Bench testing was done to prove that the Nebulae™ I would relieve over pressure conditions of 5mmHg above the preset and return to the preset within the specified time range. The device was tested with different size abdominal simulators (to address all modes and sizes of pediatric patients) and at all flow rates specified, the device relieved pressure within the specified time range.

Comparative Flow Rate Testing - The predicate devices were tested along with the Nebulae ™ I to compare the flow rates of the devices using an 11mm trocar with a 10mm laparoscope. The highest flow rates measured were 32 LPM.

{4}------------------------------------------------

K120151
Pg. 5 of 5

Pediatric Mode Comparative Testing - The Nebulae™ I was tested along with the predicate device in pediatric mode, in each of the weight modes, with a veress needle and also with a trocar. A simulated abdomen of an appropriate size for each weight mode was used. During testing in each of the weight modes, a leak was introduced and removed, and then overpressure and under pressure conditions were created. The response times were measured and compared with the predicate device and the Nebulae™ I was found to perform as well as, or better, than the predicate device.

Tissue Desiccation Effect Testing - The Nebulae™ I and the 40L Abdominal Insufflators were used in a cross comparison test to demonstrate the tissue desiccation or drying effect at their maximum flow rates while connected to a standard 5mm trocar. A typical 5mm laparoscopic instrument was inserted into the trocar sleeve to simulate an actual usage scenario. Moist bovine liver was used to show the drying effect.

Both Insufflators were set to allow their maximum achievable flow rates of CO2 to come in contact with the moist liver tissue samples. The gas flow was to remain on for 30 seconds and 60 seconds. The 5mm trocar sleeve distal opening was set in close proximity to the surface of the tissue sample. Results in both cases showed a negligible change to the tissue surface with no perceivable depth of desiccation. This was clearly evident in the crosssectional tissue samples. It was concluded that the 50LPM and the 40LPM insufflators described above were identical relative to tissue desiccation and drying.

The Nebulae™ I was tested and shown to conform to the following standards: Electrical Safety - IEC 60601-1:2005

EMC - EN 60601-1-2:2007

#### 8. Conclusion

The different technological characteristics and information submitted to the FDA do not raise new questions of safety and efficacy. Testing has shown that the device is at least as safe and effective as the legally marked predicate devices.
