# CellFX System > Active: United States. Medical device record on deviCERTS, compiled from public registries. - Canonical page: - Manufacturer: [Pulse Biosciences, Inc](https://devicerts.com/manufacturers/pulse-biosciences-inc) (FDA registration: United States) - Name in the registry: CellFX® System - Device class: Class II (US FDA) - FDA product code: GEI ## Overview *AI-generated summary, 2026-09-20. Written by a language model from registry data. Not verified by deviCERTS or the manufacturer. The registry data is the record.* The CellFX System is a Nanosecond Pulsed Field Ablation (nsPFA) Percutaneous Electrode System, designed for non-thermal cell ablation. This device leverages proprietary nanosecond pulse technology to selectively target and clear cells while preserving surrounding tissue integrity, primarily within the realm of plastic surgery applications. Its mechanism distinguishes it from traditional thermal ablation methods by delivering precise, non-thermal energy to achieve cellular disruption. The CellFX System is intended for percutaneous use and is supplied as a reusable medical device. It is cleared by the FDA under 510(k) clearance (K221671) as substantially equivalent to existing devices in the General, Plastic Surgery category. The system is not classified as MRI-safe or MRI-conditional, and its sterility, single-use or reusable status is not explicitly detailed in the regulatory submission. Storage and handling instructions are not provided in the available data. ## Registrations and authorizations - **510(k)** · FDA 510(k) · United States · K221671 · decision 2022-08-01 · decision SESE · status: Active ## Recalls No recall on record. ## Identifiers - 510(k) Number: K221671 [FDA 510(k)] - FDA product code: GEI [FDA 510(k)] ## Classification - Device class: Class II [FDA 510(k)] - Regulation: 21 CFR Part 878.4400 [FDA 510(k)] - Advisory committee: General, Plastic Surgery [FDA 510(k)] - FDA decision: SESE [FDA 510(k)] ## Source and citation - Cite as: CellFX System, Pulse Biosciences, Inc. deviCERTS medical device catalogue. https://devicerts.com/devices/cellfx-r-system-gei (data as of 2026-11-15). - Data sources: [FDA 510(k)](https://open.fda.gov/apis/device/510k/) - Registry records last synced: 2026-11-08 - Statuses computed as of: 2026-11-15 - JSON: - Licence: [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/).
