Intended Use
The CellFX® System is intended for dermatological procedures requiring ablation and resurfacing of the skin.
Device Description
The Pulse Biosciences® CellFX® System is a proprietary platform technology. The CellFX System consists of the CellFX Console, CellFX Handpiece, CellFX Treatment Tips, and CellFX Software. The CellFX System delivers nanosecond duration electrical pulses that disrupt the function of cells leading to cell death, while sparing non-cellular tissue. The CellFX System delivers a series of timed, nanosecond electrical pulses (referred to as a "Cycle") to ablate and resurface tissue areas in dermatologic conditions. The CellFX Console is capable of delivering short electric pulses at amplitudes up to 15 kV and pulse widths up to 700 ns. The electrical energy pulses are applied directly to targeted tissue using sterile Treatment Tips with stainless steel microneedles. The treatment parameters are selected by the user through a user interface on the Touchscreen Display of the CellFX Console.

No
The summary describes a device that delivers electrical pulses for skin ablation and resurfacing. There is no mention of AI, ML, image processing, or any data-driven decision-making processes within the device's operation. The user selects treatment parameters.

Yes
The device is described as "ablating and resurfacing of the skin," and the performance study shows it "successfully achieved degeneration and necrosis of active treatment sites," indicating it directly treats or modifies a physiological condition (skin issues).

No

The device is intended for dermatological procedures requiring ablation and resurfacing of the skin, which are treatment procedures, not diagnostic ones. It delivers electrical pulses to disrupt cells, a therapeutic action.

No

The device description explicitly lists hardware components: CellFX Console, CellFX Handpiece, and CellFX Treatment Tips, in addition to the software.

Based on the provided information, the CellFX® System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is for "dermatological procedures requiring ablation and resurfacing of the skin." This describes a procedure performed directly on the patient's body (in vivo), not on samples taken from the body (in vitro).
  • Device Description: The device delivers electrical pulses directly to targeted tissue using microneedles. This is a therapeutic or surgical intervention, not a diagnostic test performed on a sample.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis.

IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. The CellFX System's function is to directly treat tissue, not to analyze samples for diagnostic purposes.

PERFORMANCE DATA

The following performance data were provided in support of the substantial equivalence determination.

Biocompatibility Testing

The testing was conducted in accordance with FDA Guidance, issued June 16, 2016: Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process." All biocompatibility tests met their respective acceptance criteria.

The battery of testing included the following:

  • Material-Mediated Pyrogenicity ●
  • Systemic Toxicity ●
  • Sensitization ●
  • Irritation ●
  • Cytotoxicity
  • . Hemolysis

All biocompatibility tests met their respective acceptance criteria.

Electrical safety and electromagnetic compatibility (EMC)

The CellFX System complies with IEC 60601-1, IEC 60601-1-2, 60601-2-2. IEC 60601-1-6, IEC 62366, and IEC 62304. All test conditions were performed as outlined within the IEC standards. All electrical safety and EMC tests passed

Software Verification and Validation Testing

Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern since a failure of the device could directly result in minor injury to the patient or operator. Completed software testing supports the safety and effectiveness of the device.

Cybersecurity controls have been implemented to mitigate the risk of malware being introduced into the CellFX System as recommended by FDA's Draft Guidance for Industry and FDA Staff, "Content of Premarket Submissions for Management of Cybersecurity in Medical Devices."

Animal Study

A GLP animal safety study was conducted to validate the safety and performance of the CellFX System. The study was conducted on 15 Yucatan pigs that underwent skin treatments with either the CellFX System (test) or the predicate device (control). Animals were divided into 5 cohorts of 3 animals each for the following timepoints: 0, 2, 6, 14, and 30-days.

Safety

  • All animals survived to their termination date with no procedure related . complications. Based on the results of intra-procedural treatments, gross evaluation, histopathological analysis, clinical pathology, and in-life physical examinations the CellFX treatments are considered to be safe.

Performance

  • All test articles met the acceptance criteria for device performance. The treatment . zones met the acceptance criteria. The CellFX treatment sites successfully achieved degeneration and necrosis of active treatment sites while the epidermis remained intact. The device is expected to perform as intended.

Summary

Based on the GLP animal safety study, the CellFX System was found to have a safety and performance profile that is equivalent to the predicate device.

CONCLUSION

The CellFX® System has the same intended use as the predicate. The differences in technological characteristics between the CellFX System and predicate device do not raise any different questions of safety and effectiveness. The non-clinical performance testing and in vivo animal data provided in this submission demonstrate and support that the CellFX System is as safe and as effective as the predicate device. Therefore, the CellFX System is substantially equivalent to the predicate device.
