### 5.7 Device description

The PhotonBlade® with Adaptive Smoke Evacuation (PB2SE) is a single use, sterile, electrosurgical device with a light and adaptive smoke evacuation attachment.

The device has a monopolar electrode at the distal tip, which delivers Radiofrequency (RF) energy for cutting and coagulation of tissue. The electrode tip is located at the distal end of a rotatable and extendable shaft. The adaptive smoke evacuation attachment connects to the telescoping shaft and the cable of the PhotonBlade. It incorporates a barb connector at the end of the tubing to allow connection to a secondary suction hose connected to a smoke evacuation system. The device handle is integrated with controls for cut, coagulation, and illumination (light). A universal cable attaches the device to a 510(k) cleared electrosurgical unit.

### 5.8 Indications for Use Statement

The PhotonBlade® with Adaptive Smoke Evacuation is a monopolar RF device coupled with illumination that is indicated for cutting and coagulation of tissue during general surgical procedures and for removing smoke generated by electrosurgery when used in conjunction with an effective smoke evacuation system.

### 5.9 Comparison of Technological Characteristics

The predicate for the PB2SE electrosurgical pencil portion of the device has been identified as the previously cleared PhotonBlade® (K162053). The pencils utilize monopolar RF energy for cutting and coagulation via an insulated metal electrode. Both pencils share the same technological characteristics, operating principles and performance characteristics.

The Stryker® Neptune® E-SEP™ Smoke Evacuation Pencil (K160693) has been identified as a reference device for the smoke evacuation portion of the PB2SE. The reference ESEP pencil is used to demonstrate that the addition of a smoke evacuation function to the PB2SE electrosurgical pencil is established in a similar manner. Both electrosurgical pencils incorporate a smoke channel to remove the smoke produced from general surgical procedures utilizing electrosurgical cutting and coagulation. Both require suction from an independent smoke evacuation system to remove smoke. The devices have the same

## Technological Similarities

## PhotonBlade® vs. PhotonBlade® with Adaptive Smoke Evacuation

Fundamentally, the PB1 and PB2SE surgical pencils are based on the same intended use and technological elements.

- Energy Monopolar, Radiofrequency energy ●
- Electrode Insulated metal electrode ●
- Principle of Operation - Electrosurgical cutting and coagulation of tissue
- Illumination
- Configuration (sterile, single-use)

# Stryker® Neptune® E-SEP™ Smoke Evacuation Pencil vs. PhotonBlade® with Adaptive Smoke Evacuation

The PB2SE and E-SEP have the same principle of operation as it relates to smoke evacuation. Both devices are designed to incorporate a smoke channel. Both devices require vacuum or suction from an independent source for smoke removal capability.

# Medtronic PEAK PlasmaBlade 3.0S vs. PhotonBlade® with Adaptive Smoke Evacuation

The PEAK PlasmaBlade 3.0S and the PB2SE also have the same principle of operation as it relates to smoke evacuation. Both devices are designed to incorporate a smoke evacuation channel, and both devices require vacuum or suction from an independent source for smoke removal capability. Comparatively, the size of the smoke evacuation tubing is very similar in both length and inner diameter. Additionally, the PEAK PlasmaBlade 3.0S is also aligned to the PB2SE in that it also requires an intermediate suction tube to connect to a vacuum source, and features a pinch clamp to occlude the smoke evacuation tubing should it be required.

{8}------------------------------------------------

## Technological Differences

## PhotonBlade® vs. PhotonBlade® with Adaptive Smoke Evacuation

Two changes made to the predicate PB1 are subjects of this submission. One change (difference) involved improvements to electrical insulation components in the electrode and telescoping shaft (internal and external components). A second change (difference) involved an update to the PCBA LED driver circuit component.

# Stryker® Neptune® E-SEP™ Smoke Evacuation Pencil vs. PhotonBlade® with Adaptive Smoke Evacuation

The following technological differences exist between the subject and reference device:

- . The smoke evacuation tubing material – The E-SEP uses Ethylene Vinyl Acetate (EVA) and the PB2SE uses DEHP-free polyvinyl chloride.
- . The smoke tube dimension – The E-SEP uses a longer tube with a larger lumen diameter than the PB2SE (Medtronic PEAK PlasmaBlade reference device is similar in smoke evacuation tube dimensions).
- . The subject device requires an intermediate suction hose while the reference connects directly to the smoke evacuation system (Medtronic PEAK PlasmaBlade reference device is the same in that it requires an intermediate suction hose).
- . The subject device has an occlusion feature to shut off the suction in case the tube becomes blocked and the reference does not (Medtronic PEAK PlasmaBlade reference device is the same in that it has an occlusion feature in the form of a pinch clamp).

# 5.10 Performance Data

The PB2SE features the same operating principle and manufacturing processes, and similar technology as compared to the PB1. Testing has been performed on the device materials, components, sub-assemblies, and final assemblies to confirm the safety and effectiveness of the device.

Performance testing was conducted on the PB2SE to demonstrate compliance with the product requirements, safety and effectiveness, and substantial equivalence to the predicate.

The following product performance tests were completed; biocompatibility, performance testing, and electrical safety/electromagnetic compatibility.

# Biocompatibility

Per the "Use of International Standard ISO 10993-1, Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process," (FDA guidance, June 2016) and ISO 10993-1:2009/(R)2013, the device falls into the category external communicating device, tissue contact, less than 24- hour duration.

{9}------------------------------------------------

The only new contacting material introduced with the subject device is the smoke evacuation tubing. Biocompatibility testing was performed on the material and confirmed to be biocompatible for its intended use.

# Electrical Safety and Electromagnetic Compatibility (EMC)

Electrical safety testing and EMC testing were conducted per IEC 60601-1:2005 + A1:2012 with US deviation, IEC 60601-2-2:2017 (6th Edition) and IEC 60601-1-2:2014 (4thEdition), and AIM 7351731 Rev 2.00 standards. The device complies with the relevant sections of the standards.

# Mechanical and Functional Testing

Mechanical and functional testing were performed on conditioned samples (EtO sterilization, distribution simulation, and 24 months accelerated aging) to confirm design inputs. The results confirm the product meets the specifications and acceptance criteria.

# Smoke Evacuation

No standard requirements specific to the smoke performance exist, however, tests were conducted with the device to verify the device meets the design requirements, performance specifications, and intended use. The design of the smoke evacuation attachment does not affect or change the function of the electrosurgical device. The smoke evacuation flow rate was evaluated and compared between the PB2SE and the reference device PEAK PlasmaBlade 3.0S, demonstrating equivalent or better flow rate. The intake portion of the device did not obstruct the electrosurgical function of the pencil, while removing smoke. The results demonstrate the product is safe, effective, and meets the requirements for technology, performance and intended use.

# 5.11 Conclusion

The data presented for the PhotonBlade® with Adaptive Smoke Evacuation with respect to the device function, intended use, technological, and biological characteristics demonstrate that it is as least as safe and effective as the predicates. Any differences between the subject device and the predicate/reference devices do not raise any different issues of safety and effectiveness. A determination of substantial equivalence is supported.
