Yes.
A therapeutic device is one that treats or alleviates a disease or condition. This device is intended for "surgical ablation of soft tissue by irreversible electroporation," which is a treatment for certain medical conditions.
No
The device is intended for surgical ablation of soft tissue, indicating a therapeutic purpose rather than a diagnostic one.
No
The device description explicitly lists multiple hardware components (Power Generator, Trigger Probe, Standard Probe, Fixator support, Foot Switch) that are part of the system.
Based on the provided information, the Dophi Electroporation System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is "surgical ablation of soft tissue by irreversible electroporation." This describes a therapeutic procedure performed directly on a patient's tissue, not a test performed on a sample taken from a patient outside the body.
- Device Description: The device components (power generator, probes, foot switch) are designed for delivering electrical pulses to tissue within the body for ablation.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.) or providing diagnostic information based on such analysis.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. The Dophi Electroporation System's function is to directly treat tissue, not to diagnose or analyze.

Device Description
The Electroporation System consists of Electroporation Power Generator, Electroporation Trigger Probe, Electroporation Standard Probe, Electroporation Fixator support and Foot Switch. The single-use Electroporation Trigger Probe with EO sterilization is the same as Electroporation Standard Probe and Electroporation Fixator support. The Electroporation Power Generator and Foot Switch are non-sterile and reusable. With the Electroporation System, a voltage applied between pairs of probes in a series of pulses. The waveform of the voltage is adjustable as determined by clinician-chosen parameters. These parameters include volts, pulse width, pulse frequency and the distance between probes. Up to six probes may be placed in an array within the tissue. The probes of the array are matched as pairs by the system. When probes are activated via a foot switch, the scheduled voltage is delivered to tissue between subsequent pairs of probes. Soft tissue between the probes is ablated.

Dear Guofang Ma:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrb/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
