## 6 SUMMARY OF NON-CLINICAL TESTING

The following non-clinical testing is provided in support of our substantial equivalence claim and to demonstrate compliance with the special controls associated with this device type:

## Sterilization and Shelf-Life:

Sterilization validation was performed in accordance with ISO 11135, Sterilization of health-care products - Ethylene oxide - Requirements for the development, validation and routine control of a sterilization process for medical devices.

Shelf-life of 18 months was validated on device samples following accelerated aging and simulated transit conditioning. Testing evaluated packaging integrity and device functionality

## Biocompatibility:

The biocompatibility evaluation for the LapBox Power Tissue Containment System device was conducted in accordance with the FDA biocompatibility guidance “Use of International Standard ISO 10993-1, ‘Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process” issued September 2023 and International Standard ISO 10993-1 “Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process,” as recognized by FDA. The LapBox is considered an externally communicating device, tissue contacting with limited duration.

The following biocompatibility tests were conducted:

- Cytotoxicity per ISO 10993-5
- Sensitization per ISO 10993-10
- Intracutaneous irritation per ISO 10993-10
- Acute Systemic Toxicity per ISO 10993-11
- Pyrogenicity testing per USP <151>

Testing demonstrated that the device was non cytotoxic, non-sensitizer, non-irritant, not systemically toxic and non-pyrogenic.

## Non-Clinical Performance Testing (Bench):

Non-clinical performance testing on LapBox Power Tissue Containment System was conducted in accordance with the FDA guidance document “Non-Clinical Performance Assessment of Tissue Containment Systems Used During Power Morcellation Procedures” issued May 26, 2023.

Testing included:

- Bacterial Immersion Test: testing included 32 device samples aged beyond shelf life and previously exposed to simulated use; both positive and negative controls were used. Samples were then disinfected and sterilized prior to immersion. The tested chambers were inflated and immersed to assess for impermeability to Brevundimonas Diminuta. After the Immersion Test the entire volume of the TSB within each chamber was membrane filter plated to enumerate the presence of a single colony forming unit of the bacterial species. The test samples did not show any evidence of growth of Brevundimonas Diminuta. The positive and negative controls performed as intended.
- Dimensional Verification Tests: supplemental test to the one provided in K221365 (referenced below); a total of 30 non aged units were tested for the dimensions of the following: proximal handle outer diameter; inner tube inner diameter: outer tube inner diameter; and inflation chamber inner diameter. All samples met the prespecified

{8}

ARK SURGICAL

LapBox Power Tissue Containment System K250212

acceptance criteria.

- Pressure Relief Valve Testing: a total of 30 aged and 30 non aged pressure relief valves were tested to ensure they would relieve pressure above the set target. All samples met the prespecified acceptance criteria.
- Design and Performance Validation Test: a total of 30 aged and 27 no-aged units were tested by 2 trained surgeons using two different morcellators in a simulator with bovine tongue. All samples passed a dye leak test. Design changes were implemented following this test which were validated in supplemental tests.
- Puncturing Force Comparative Test: testing was conducted on double layers and a single layer of the LapBox chamber material with a variety of morcellator and graspers and compared to the results obtained with the predicate. Testing utilized 72 predicate material samples and 72 aged and 72 non aged LapBox material samples. The results obtained with LapBox supported non-inferiority when compared to the predicate.
- Bond Strength Tests: supplemental test to the one provided in K221365 (referenced below); 30 aged units were tested to evaluate the air tube bond connection as well as the handpump assembly. All samples met the prespecified acceptance criteria.
- Burst Pressure Evaluation: supplemental test to the one provided in K221365 (referenced below); 10 non-aged units with the modified new air tube were tested. All samples met the prespecified acceptance criteria.
- Inflation Pressure Range: a customized jig was developed to evaluate the pressure range required for the LapBox chamber to maintain its shape when subjected to insufflation. One LapBox unit was used. The testing demonstrated that the chamber will maintain its shape at a pressure below that relieved by the pressure relief valve.
- Comparison Force Test: a customized jig was developed to evaluate and compare the outward force exerted by the LapBox and by the predicate. One predicate and one LapBox were utilized in this test. The results demonstrate that when used in accordance with device labeling, a uniform distribution of force by LapBox does not pose a greater risk of compression on adjacent organs when compared to the predicate.

The following additional bench tests previously submitted under K221365 for the reference device were also considered:

- Corrosion Resistance: 30 units of the 2 different metal components were used; samples underwent double sterilization and 18 months accelerated aging prior to testing. No corrosion was noted on any samples.
- Burst Pressure Evaluation: a total of 30 aged and 30 non-aged units were tested to evaluate the burst pressure of the LapBox chamber. All tested units met the prespecified acceptance criteria.
- Bond Strength Tests: 30 non-aged units and 30 aged units were tested. Tensile strength of the following bonds were assessed: chamber assembly; air tube-chamber connection; delivery system-chamber connection; and the handpump assembly. All samples met the prespecified acceptance criteria.
- Dimensional Verification Tests: a total of 36 non aged units were tested for the dimensions for the following: shaft effective length; inner sleeve height; chamber double wall height; chamber outer diameter; and chamber opening. All samples met the prespecified acceptance criteria.
- Viral Penetration ASTM Method F 1671: 30 material samples that have undergone

accelerated aging equivalent to 12 months were tested. All samples met the prespecified acceptance criteria.

- Maximum organ size testing: 2 aged devices used to evaluate the maximum organ size compatible with the LapBox.

## Training Validation and Usability Studies:

Multiple studies were conducted to evaluate the usability of the LapBox System and the training program developed by ARK Surgical.

- An initial usability study was conducted which included 31 physicians of varying levels of experience performing a total of 40 procedures in a simulator with bovine tongue. Following training, participants performed the procedure. No device samples had an observed leakage of dye following use. There were minor device issues noted that were addressed via manufacturing and labeling modifications.
- A supplementary usability study in a simulator was conducted, in which 6 physicians conducted a total of 33 procedures. These units were used in the bacterial immersion testing discussed above. There was no evidence of any device leak.
- Training validation was conducted in a porcine model with bovine tongue. A total of 16 physicians of varying levels of experience completed 32 morcellation procedures. The participants underwent the training and then had a 1 hour break prior to performing the procedure. Following the procedure, device samples were subject to a dye leak test. No samples leaked. Minor issues were noted with respect to adherence to the instructions for use. The training and instructions for use (IFU) were revised to address the noted issues and a follow-up usability study was conducted which included 15 physicians who performed 30 power morcellation procedures in a simulator. This study demonstrated that the revisions made to the training and IFU were effective, ensuring the device's safe and effective use in clinical settings.

## Additional Animal Studies:

- Performance Characterization Animal In-Vivo Study (Part 1 and 2): The purpose of these studies was to define the performance characteristics of the LapBox System in a porcine model. The first study utilized one animal and evaluated 3 devices, the second study utilized one animal and evaluated 5 devices.

c. Demonstration that the containment system provides adequate space to perform morcellation and adequate visualization of the laparoscopic instruments and tissue specimen relative to the external viscera.
d. Demonstration that intended laparoscopic instruments and morcellators do not compromise the integrity of the containment system.
e. Demonstration that intended users can adequately deploy the device, morcellate a specimen without compromising the integrity of the device and remove the device without spillage of contents.

5. Training has been developed and validated to ensure users can follow the instructions for use.

6. Labeling includes:

- Contraindication for use in gynecologic surgery in which the tissue to be morcellated is known or suspected to contain malignancy.
- Contraindication for removal of uterine tissue containing suspected fibroids in patients who are: peri- or post-menopausal; or candidates for en bloc tissue removal, for example, through the vagina or via a mini-laparotomy incision.

Note: The language of this contraindication was revised during the review of the predicate device for clarity. The labeling for the LapBox Power Tissue Containment System is consistent with the predicate device and identifies the contraindication as follows: "Do not use for removal of uterine tissue containing suspected fibroids in patients who are: post- menopausal or over 50 years of age; or candidates for en-bloc tissue removal through the vagina or via a mini-laparotomy incision."

- The following boxed warning: "Warning: Information regarding the potential risks of a procedure with this device should be shared with patients. Uterine tissue may contain unsuspected cancer. The use of laparoscopic power morcellators during fibroid surgery may spread cancer. The use of this containment system has not been clinically demonstrated to reduce this risk."
- Statement limiting use of device to physicians who have completed the training program.
- An expiration date or shelf life.

# 8 CONCLUSION

The LapBox Power Tissue Containment System's performance testing support the substantial equivalence determination as well as compliance with the special controls. The LapBox Power Tissue Containment System is as safe and effective as the predicate device.
