2. Sample Size Used for the Test Set and the Data Provenance

The document does not explicitly state the specific sample sizes used for each performance test. It refers to "representative samples" for stability and environmental testing.

Data Provenance: The studies were non-clinical (electrical, mechanical, functional) performance testing and preclinical (bench) evaluations and testing. These are laboratory-based tests, not human trials.
Country of Origin: Not specified, but conducted by Gyrus ACMI, Inc. a US-based company with manufacturing in Bartlett, TN, USA.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

Not applicable. This device's performance was evaluated through non-clinical and preclinical bench testing against objective criteria and comparison to a predicate device, not through expert-reviewed clinical data or human studies.

4. Adjudication Method for the Test Set

Predicate Device

Medtronic Endo-scrub 2:

K982594

Product Description

When performing ESS the scope is inserted into the nasal passages to visualize the sinuses. During the resection of tissue the scope lens is frequently covered in debris. such as blood and mucous that limits visualization. Traditionally the surgeon has to remove the scope, clean the lens, return the scope, and resume surgery. The proposed device is intended to attach directly to the endoscope shaft and provide fluid and suction to clean the lens of unwanted debris. This provides the surgeon with better images without debris and less instrument exchanges.

Technological Characteristics

The system is used in the same way as the predicate system (K982594). The disposable sheath is placed on the shaft of an endoscope and directs fluid to the lens of the scope for the purpose of cleaning the lens of debris. Fluid delivery is actuated by a simple footpedal. Other than the footpedal and the console there are no other capital requirements. Fluid is pressurized using a pump on the console. The flow rate may be controlled by an adjustable knob on the back of the console. Connections to the console are limited to loading the tubeset through the pump, and connecting the footpedal.

Material

The system uses the same patient-contacting materials that are utilized in predicate devices, as well as other legally marketed devices manufactured by Gyrus ACMI.

The patient contacting items are classified in accordance with ISO 10993-1, as an external communicating. tissue/bone/dentin device for limited exposure (<24hrs.). ISO

{5}------------------------------------------------

10993-1 and FDA Blue Book memo #G95-1 guidelines recommend that these direct patient contact parts have supporting data for cytotoxicity, sensitization and irritation. Full GLP biocompatibility testing (Cytotoxicity, sensitization, and irritation) on similar devices containing all patient contacting materials is on file for other devices currently marketed by Gyrus ACMI.

Intended Use / Indications

Intended to clear the end of a rigid rod endoscope in order to maintain clear visualization of endoscopic procedures without having to remove the scope from the surgical site.

The device is indicated for use during routine diagnostic procedures and during endoscopic sinus surgery.

Compliance to Standards

The design of the system complies with the following standards:

IEC 60601-1, IEC 60601-1-2, IEC 60601-2-18 ISO 10993-1, 5, 7, 10, Biological Evaluation of Medical Devices ISO 14971, Risk Analysis ISO 15223-1:2012, Medical Devices - Symbols to be used ISO 11135:2014, Sterilization of Health Care Products, EO Validation ISO 11138: 2006, Sterilization of health care products: Biological Indicators ISO 11607-1:2006, Packaging for Terminally Sterilized Medical Devices ISO 11607-2:2006, Packaging for Terminally Sterilized Medical Devices ISO 11737-1:2006, Sterilization of Medical Devices - Microbiological Methods ISO 11737-2:2009, Sterilization of Medical Devices - Microbiological Methods

Risk analysis was carried out in accordance with established in-house acceptance criteria based on ISO 14971. The design verification tests were identified and performed as a result of risk analysis assessment.

Electrical safety and electromagnetic compatibility (EMC)

Electrical safety and EMC testing were conducted on the device complies with the applicable clauses of IEC 60601-1, and the IEC 60601-1-2 standard for EMC.

{6}------------------------------------------------

Summary of Sterilization and Shelf Life Discussion

The system console and footpedal are provided non-sterile and are reusable. The console and footpedal are to be wiped down with cleaning / disinfecting wipes after use.

The sheaths and tubesets are provided sterile for single-use. They are sterilized with Ethylene Oxide, using a cycle validated in accordance with ISO 11135 to provide a sterility assurance level of 10-6.

The Shelf Life period for the disposable items was determined through an analysis of the shelf-life stability of the materials used in the design of the devices, as well as an analysis of the packaging materials and processes used with other Gyrus ACMI devices. Shelf-life studies are on file to support an initial one year shelf life.

Summary of Performance Testing

Performance tests were executed to ensure that the system functioned as intended and met design specifications. The following non-clinical and preclinical tests and usability studies were conducted:

Non-Clinical / Preclinical Performance

Evidence of safety and effectiveness was obtained from two primary areas:

1. non-clinical (electrical, mechanical, functional) performance testing
1. preclinical (bench) evaluations and testing

Non-clinical: Basic safety and performance testing was performed in accordance with IEC standards. In addition, verification and comparison bench studies were conducted to evaluate the mechanical and functional performance. Testing included: cleaning compatibility, noise levels, heat generation, tabletop stability, burst pressure, suction strength, hub strength, torque strength, leak testing, ship testing, and baseline performance testing.

Stability: Representative samples were subjected to accelerated aging to confirm that the disposable devices maintain functionality and continues to meet specifications over time. The results of the accelerated age testing demonstrate that the device will be stable for the stated shelf-life. In addition, real time age testing will confirm the results of the accelerated age testing. Representative samples were also subjected to environmental conditioning and ship testing.

Preclinical: Evidence obtained from preclinical bench studies demonstrate that the system performs substantially equivalent to the predicate device in relevant aspects associated with cleaning cycle time, cleaning performance, clearing performance, and

{7}------------------------------------------------

leak / drip occurrence rate. For simulated use and bench testing. the selected medium was a blood analog appropriate for testing.

Testing demonstrated that the device performs as well as or better than the predicate device.

No clinical testing was conducted. The use of the device type has been documented in published literature and indicates safe and effective use for the target procedures and expected patient populations.

Substantial Equivalence

The system operates in a similar manner as the predicate device. The disposable tubeset and sheaths are similar to the predicate devices physically and in their methods of operation. The tubeset offers irrigation to the surgical site and suction away from the surgical site.

The system uses similar or same patient-contacting materials in similar quantities that are utilized in the predicate device, as well as other legally marketed devices manufactured by Gyrus ACMI.

Conclusion

The performance of the InstaClear system was compared against the known performance characteristics of the predicate device. Testing demonstrated that the performance requirements were met, and that the system exhibited comparable performance characteristics to the predicate.

In summary, the InstaClear Lens Cleaner is substantially equivalent to the predicate device and presents no new questions of safety or efficacy.
