The PhotonBlade is a monopolar RF device coupled with illumination that is indicated for cutting and coagulation of tissue during general surgical procedures.

Device Description

The PhotonBlade is a single use, sterile, electrosurgical device with a light. The PhotonBlade has an electrode at the distal tip, which delivers RF energy for cutting and coagulation of soft tissue. The electrode tip is located at the distal end of a rotatable and extendable shaft. 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.

AI/ML Overview

The provided text describes the PhotonBlade device, an electrosurgical device with illumination, and its comparison to predicate devices for FDA 510(k) clearance. However, it does not contain information about acceptance criteria, a specific study proving the device meets those criteria, sample sizes for test or training sets, data provenance, expert ground truth establishment, adjudication methods, or MRMC studies for AI devices.

The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to legally marketed predicate devices, primarily through engineering and bench testing, rather than clinical trials or AI performance evaluations.

Given the information provided in the text, I can only report what is included:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not explicitly present a table of acceptance criteria with corresponding device performance metrics. Instead, it lists various performance tests conducted to demonstrate compliance with product requirements, safety, efficacy, and substantial equivalence to the predicate devices. These tests generally assess the device's capability to perform its stated functions.

Test CategoryDescription / Performance Demonstrated
Mechanical TestingConducted on PhotonBlade devices exposed to EO sterilization and simulated transportation to demonstrate compliance with product requirements.
Electrical Safety / EMC TestingDemonstrated compliance with: - IEC 60601-1 3rd Edition - IEC 60601-2-2
Operational TestingConducted on PhotonBlade devices exposed to EO sterilization and simulated transportation to demonstrate compliance with product requirements. (Specific operational metrics are not detailed, but it implies the device functions as intended for cutting and coagulation, and illumination.)
Ex-vivo Thermal Effects on Tissue ComparisonsConducted to demonstrate safety and efficacy. (Specific results or comparisons are not detailed, but the aim is to show comparable or acceptable thermal effects to predicate devices. The document states: "PhotonBlade and PlasmaBlade both have insulated electrodes that extend and rotate. Both devices utilize blade electrodes where only the edge of the blade is exposed or active. As such, the principles of operation involved in cutting and coagulation of tissue are the same on either device.")
BiocompatibilityDemonstrated compliance with ISO 10993-1.
Packaging EvaluationConducted to demonstrate compliance with product requirements.
SterilizationSterile-Ethylene Oxide.
Illumination OutputPhotonBlade: 28 lumens (n=29) PARE Surgical NOVA ES: 30 lumens (n=1) (This is a comparison point, not an acceptance criterion, but it shows the measured output for the illumination feature).
Shelf Life StudiesProduct Shelf Life studies for 7 months and 37 months will be conducted. (This indicates ongoing or planned studies, not necessarily completed ones with reported performance for final acceptance in this document.)
Overall ConclusionThe data submitted support the substantial equivalence claim for the proposed indications for use; the PhotonBlade is as safe and effective as the predicate device(s). Invuity Inc. considers the PhotonBlade device to be substantially equivalent to the legally marketed predicate device(s) with respect to the device function, intended use, and patient population. Any differences in technological characteristics between the PhotonBlade device and the predicate device(s) do not raise any new issues of safety and effectiveness.

Comparison to Predicate Device(s)-Illumination (Lighted ES Pencil)

Technological Characteristics 5.9

The PhotonBlade device is similar to both predicate devices in that they are electrosurgical instruments used to cut and coagulate soft tissue utilizing RF energy.

PhotonBlade and PlasmaBlade both have insulated electrodes that extend and rotate. Both devices utilize blade electrodes where only the edge of the blade is exposed or active. As such, the principles of operation involved in cutting and coagulation of tissue are the same on either device. The differences between the PhotonBlade and PlasmaBlade are:

  • 0 The PlasmaBlade device has aspiration and the PhotonBlade does not.
  • . The PlasmaBlade is compatible with a dedicated electrosurgical unit (ESU) or generator and the PhotonBlade is intended for use with general purpose FDA-cleared RF generators with the standard or traditional (Bovie) three plug receptacle, such as the Valleylab (Medtronic) Force FX c and Conmed S5000 for example.
  • The PhotonBlade has a light and the PlasmaBlade does not. 0

The PhotonBlade and NOVA ES Pencil lights both provide illumination using LED technology. In both devices, the illumination is powered by a battery; however, the PhotonBlade battery is replaceable, while the NOVA ES Pencil battery is not. The NOVA ES Pencil electrode tip is not insulated, and the device is provided with two tip configurations (one long and one short). The

The logo consists of a circular icon with a blue and green color scheme, followed by the company name in bold, black letters. Below the company name, the words "intelligent photonics" are written in a smaller, lighter font.

PhotonBlade has an insulated tip with only one configuration that can be adjusted via an extendable shaft. The NOVA ES Pencil has three LEDs that are located in the handle of the device; the distance from the electrode tip to the LEDs varies depending on the tip configuration. The PhotonBlade has one LED that is located in the shaft of the device; the distance from the electrode tip to the LED is constant (approx. 2cm).

The differences identified between the PhotonBlade and its two predicates (PlasmaBlade and NOVA ES Pencil Surgical Light Source) do not present any new concerns of safety and effectiveness.

5.10 Summary of Performance Data

Performance testing was conducted on PhotonBlade devices that were exposed to EO sterilization and simulated transportation to demonstrate compliance with the product requirements and to demonstrate safety, efficacy, and substantial equivalence to the predicate. The following product performance tests are included: mechanical, electrical safety/electromagnetic compatibility, operational, ex-vivo thermal effects on tissue comparisons, biocompatibility, and packaging evaluation. Product Shelf Life studies for 7 months and 37 months will be conducted.

Like the predicate device(s), no clinical testing was necessary to support substantial equivalence. The data submitted support the substantial equivalence claim for the proposed indications for use; the PhotonBlade is as safe and effective as the predicate device(s).

5.11 Conclusion

Invuity Inc. considers the PhotonBlade device to be substantially equivalent to the legally marketed predicate device(s) with respect to the device function, intended use, and patient population. Any differences in technological characteristics between the PhotonBlade device and the predicate device(s) do not raise any new issues of safety and effectiveness. The Invuity PhotonBlade is substantially equivalent to the proposed predicate devices.
