No
The summary describes a reprocessed electrosurgical stylet that delivers RF energy and relays temperature/feedback to a separate generator. There is no mention of AI or ML in the device description, intended use, or performance studies.
Yes
The device is described as "intended for use in vessel and tissue coagulation including: Treatment of incompetent (i.e. refluxing) perforator and tributary veins," which clearly indicates a therapeutic purpose.
No
The device is intended for vessel and tissue coagulation and delivers RF energy for treatment, not for diagnosing conditions.
No
The device description clearly states it is a physical stylet with a shaft, handle, cable, and tip, made of materials like stainless steel and polyimide. It is a hardware device that delivers RF energy.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "vessel and tissue coagulation" and "Treatment of incompetent (i.e. refluxing) perforator and tributaiy veins." This describes a therapeutic procedure performed directly on the patient's body.
- Device Description: The device is a "high frequency electrosurgical system designed for blood vessel and tissue coagulation." It delivers RF energy to the treatment site. This is a surgical tool used for treatment, not for analyzing samples from the body.
- IVD Definition: In Vitro Diagnostics (IVDs) are medical devices used to perform tests on samples taken from the human body (such as blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
This device is clearly used in vivo (within the living body) for a therapeutic purpose, not in vitro (in glass, i.e., in a lab) for diagnostic purposes.

Device Description
The NES Reprocessed RF Stylet (RFS) is a reprocessed VNUS RFS (510(k) # K052003). The device is a high frequency electrosurgical system designed for blood vessel and tissue coagulation in general surgical procedures. This device's energy source comes from a compatible and separately cleared Radiofrequency (RF) Generator. The device has been validated to be reprocessed a maximum of one time.
The NES Reprocessed RF Stylet (RFS) is provided sterile (EtO) and is a single use, disposable device. The device is used in a healthcare facility. The device's function is to deliver RF energy to the desired treatment site and relay temperature and other information to the RF Generator. The device consists of one model.
The device itself consists of the stylet shaft, handle and cable. A sharp is included with the device for patient insertion. The tip of the stylet serves to deliver the RF energy to the desired treatment site while the cable plugs into the RF generator (for power and relay temperature/other feedback). The tip, inner and outer lumen are the only patient-contacting parts. The patient-contacting material is as follows: AISI 304 SST and polyimide. All patient-contacting material has proven to be biocompatible. The non patient-contacting material is as follows: poly methyl methacrylate and polypropylene. The device is compatible with the separately cleared Radiofrequency (RF) Generator. The NES Reprocessed RF Stylet (RFS) is considered an external communicating device with circulating blood contact for a duration of less than 24 hours.

V. INDICATIONS FOR USE
The NES Reprocessed RF Stylet (RFS) is intended for use in vessel and tissue coagulation including:
- · Treatment of incompetent (i.e., refluxing) perforator and tributary veins.
Note: The indications for use are identical to the predicate's indications for use as seen below.
VI. INDICATIONS FOR USE OF PREDICATE DEVICE
The VNUS RFS is intended for use in vessel and tissue coagulation including:
- Treatment of incompetent (i.e., refluxing) perforator and tributary veins.
VII. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The NES Reprocessed RF Stylet (RFS) and its predicate, VNUS RFS, are substantially equivalent in technological characteristics. Both stylet devices share identical composition and energy sources. Both stylet devices share identical clinical applications, performance specifications, clinical procedures and patient population. The NES Reprocessed RF Stylet (RFS) and the predicate use the same temperature, power and impedance ranges during the treatment cycle. There are no changes made to the design, material, chemical composition or energy sources of the VNUS RFS when reprocessed to the NES Reprocessed RF Stylet (RFS). NES does provide the user with a new sharp that has a slightly different material composition (different poly plastics in non patient-contacting parts), however, it has been shown to have substantial equivalence in function and form when compared to the sharp supplied with the predicate. The device itself, however, does not undergo any design, material, chemical composition or energy source changes.
