Intended Use
The Pajunk Plexalong Sets are intended for delivery of continuous conduction anesthesia of peripheral nerves and plexus for up to 72 hours. Continuous delivery for up to 72 hours is accomplished using the Polyamide indwelling catheter. An electrical stimulus may be applied to the conduction needle via a cable and connectors to assist the physician pinpoint the area of application.
Device Description
The Pajunk Plexalong sets are single use, sterile, non-pvrogenic and latex free conduction anesthesia sets intended for delivery of continuous conduction anesthesia of peripheral nerves and plexus for up to 72 hours. The Plexalong sets consist of a single use sterile, non-pyrogenic conduction needle with tubing, stilett, a catheter and catheter adapter. The stylet is used to stop tissue from clogaing the needle (during insertion) by blocking the opening at the tip of the needle. Pajunk changed the stilett material from a surgical stainless steel to polycarbonate. The Unipolar needles used in the Plexalong sets are available in three tip configurations. A Unipolar needle with a facet tip, Sprotte tip or Unipolar needle with a Tuohy tip. Only Plexalong sets with the Tuohy needles are affected by the stilett material change. To assist the physician pinpoint the area of application, an electrical stimulus can be applied to the tip of the conduction needle via a nerve stimulus connector.
More Information

Not Found

No
The summary describes a mechanical device for delivering anesthesia with an electrical stimulus for localization. There is no mention of AI or ML in the intended use, device description, or performance studies.

Yes.
The device is intended for the delivery of continuous conduction anesthesia, which is a therapeutic intervention, to provide pain relief or facilitate surgical procedures.

No

The device is intended for the delivery of continuous conduction anesthesia, which is a therapeutic purpose. While it mentions an electrical stimulus to "assist the physician pinpoint the area of application," this function is to aid in the precise delivery of the anesthetic, not to diagnose a condition or disease.

No

The device description clearly outlines physical components such as needles, tubing, stylets, catheters, and connectors, indicating it is a hardware-based medical device. While it mentions an electrical stimulus can be applied, this is a function of the hardware, not a standalone software component.

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

Here's why:

  • Intended Use: The intended use is for "delivery of continuous conduction anesthesia of peripheral nerves and plexus." This is a therapeutic procedure performed directly on the patient's body.
  • Device Description: The device components (needles, catheters, stylets) are designed for insertion into the body to deliver medication and potentially electrical stimulation.
  • Lack of In Vitro Testing: There is no mention of the device being used to test samples (like blood, urine, or tissue) outside of the body. IVDs are specifically designed for such testing.

Therefore, the Pajunk Plexalong Sets are medical devices used for a therapeutic procedure, not for in vitro diagnostic testing.

Dear Mr. Brandt:

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 (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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
