Intended Use

The AURORA Evacuator +Coag is a powered instrument with a handpiece intended for removal of soft tissue and fluids, and coagulation of tissue under direct visualization. Types of direct visualization may include laparoscopic, pelviscopic, endoscopic, percutaneous, and open.

Device Story

AURORA Evacuator +Coag is a sterile, single-use, battery-powered handheld instrument for minimally invasive surgery. Device features a wand with a side aspiration window containing an internal rotating whisk (301 SS) to break up/aspirate soft tissue and fluids via external vacuum source. Bipolar electrodes (silver) at the distal tip connect to an external electrosurgical generator for tissue coagulation. An irrigation line allows saline delivery to clear the surgical field. Operated by surgeons in OR settings; vacuum pressure controlled via handle vent; whisk activated by handle button. Green LED indicates power availability. Device combines aspiration, mechanical tissue disruption, and bipolar electrosurgical coagulation to clear surgical sites and manage bleeding. Benefits include integrated multi-functional capability in a single handheld device, reducing instrument exchanges during procedures.

Clinical Evidence

No clinical data. Evidence consists of bench testing and ex-vivo studies. Bench testing included biocompatibility (ISO 10993-1), electrical safety (IEC 60601-1, IEC 60601-2-2), EMC (IEC 60601-1-2), particulate testing (USP <788>), sterilization (ISO 11135-1), and shelf-life (ISTA 2A, ASTM F1980-16). Ex-vivo studies on porcine heart, liver, and kidney demonstrated comparable thermal damage (coagulation zone) and tissue temperature profiles between the subject device and the primary predicate.

Technological Characteristics

Handheld, battery-powered (6V Alkaline). Wand: 304 SS, 7-13 cm length, 12 F OD. Electrodes: Bipolar, silver, polyphenylsulfone insulation. Whisk: 301 SS. Connectivity: External vacuum (barb), external electrosurgical generator (bipolar cable), external irrigation (luer). Sterilization: Ethylene oxide (SAL 10^-6). Standards: ISO 10993-1, IEC 60601-1, IEC 60601-1-2, IEC 60601-2-2, USP <788>, ISO 11135-1, ISTA 2A, ASTM F1980-16.

Indications for Use

Indicated for removal of soft tissue/fluids and tissue coagulation under direct visualization (laparoscopic, pelviscopic, endoscopic, percutaneous, open) in patients requiring minimally invasive surgical procedures.

### DEVICE DESCRIPTION

The subject device, AURORA Evacuator +Coag, is provided sterile, for single use only. It is a disposable, handheld, battery powered instrument that combines the ability to remove fluids and soft tissue, apply bipolar energy for the coagulation of tissue, and apply irrigation directly to clear the surgical site during minimally invasive surgical procedures.

It consists of a wand and handle with connection ports for a bipolar electrode cable, vacuum source (for aspiration) and irrigation line. At the distal tip of the wand, a side aspiration window with an internally rotating whisk is provided to break up and aspirate soft tissue and fluids. The battery and motor that powers the whisk is contained in the device handle. Bipolar electrodes are located at the distal tip of the wand and can be activated to coagulate tissue when connected to an electrosurgical generator. When desired, an irrigation line may be connected to the handle and saline can be delivered to clear the surgical field as a procedural aid.

Bipolar electrosurgical generator/cables, vacuum source, and irrigation source are not provided with the device. Prior to use, the device is to be connected to electrosurgical generator, external vacuum source (i.e. operating room suction) and irrigation source (i.e. drip).

A green power indicator light is located on the top portion of the handle to show that power is available to the device. A suction control vent for the user to control vacuum pressure and a button for activating the whisk are located conveniently on the handle.

### SUMMARY OF NON-CLINICAL TESTING

The following testing was conducted to demonstrate the safe and effective use of the AURORA Evacuator +Coag:

- Biocompatibility Testing per ISO 10993-1, including Cytotoxicity (MEM Elution), Sensitization ● (Kligman Maximization), Irritation (Intracutaneous Injection), Systemic Toxicity (Systemic Injection), Materials Mediated Pyrogenicity
- Electrical Safety and Enclosure Protection per IEC 60601-1 and IEC 660601-2-2 ●
- Emissions and Immunity per IEC 60601-1-2
- Particulate Testing per USP <788>
- Sterilization per ISO 11135-1 to validate a SAL of 10-6 ●
- Packaging and Shelf-life per ISTA 2A and ASTM F1980-16
- . Verification of product specifications including materials, multiple bonds evaluations, physical characteristics, performance characteristics and tissue thermal effects (coagulation of tissue).

Ex-vivo tissue studies (porcine heart, liver, and kidney) demonstrated comparable thermal damage effect (coagulation zone) using the bipolar electrodes when compared with the primary predicate under the same test parameters and conditions. Thermal damage as a function of temperature and time with the 3 tissue types also supported comparability.

- Validation of product performance using surrogate soft tissue materials and fluids.
### CONCLUSION

Based upon the performance data provided in this submission and comparing indicated use, design, materials, principle of operation and overall technological characteristics, the AURORA Evacuator +Coag has been determined to be substantially equivalent to the predicate device.

The ex-vivo tissue studies (porcine heart, liver, and kidney) demonstrated comparable thermal damage effect (coagulation zone and tissue temperature studies) using the bipolar electrodes when compared with the primary predicate under the same test parameters and conditions.
