More Information

No
The summary describes a traditional ultrasonic surgical aspirator system and does not mention any AI or ML components or capabilities.

Yes
The device is intended for the fragmentation, emulsification, and aspiration of tissue in various surgical specialties and for wound debridement, which are therapeutic interventions.

No

This device is intended for the fragmentation, emulsification, and aspiration of tissue in surgical procedures and wound care, which are therapeutic actions, not diagnostic ones.

No

The device description explicitly states the system includes a generator housed inside a console and a reusable handpiece, which are hardware components.

Based on the provided information, the Misonix Inc. neXus Ultrasonic System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use clearly states the device is for the "fragmentation, emulsification and aspiration of both soft and hard (i.e., bone) tissue" in various surgical specialties and wound care. This describes a surgical tool used directly on the patient's body during a procedure.
  • Device Description: The description details a system with a generator, handpiece, probes, irrigation, and aspiration system. These are components of a surgical device used for tissue manipulation and removal.
  • Lack of IVD Characteristics: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue samples) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. The neXus system does not perform any such analysis on specimens. It is used in vivo (within the body) during surgery.

The device is a surgical aspirator system, which is a type of medical device used in surgical procedures.

DEVICE DESCRIPTION 3.

The neXus Ultrasonic Surgical Aspirator System is intended for fragmentation, emulsification and aspiration of both soft and hard (i.e., bone) tissue. The system includes a generator housed inside the console. A reusable handpiece is plugged directly into the front panel of the console.

The generator and handpiece are compatible with various single use disposable "probes" which are selected and attached to the handpiece by the end user. An irrigation unit provides sterile irrigant to the operative site. An aspiration system removes the fragmented, emulsified material and waste liquids from the operative site.

Accessories include a wireless footswitch, various probe tip combinations, sterilization trays, probe covers, assembly & disassembly wrenches, irrigation tubing sets, and waste collection canisters.

PERFORAMNCE DATA 6.

Biocompatibility Testing

The ultrasonic tip (and sheath, when applicable) are direct patient contacting devices classified as externally communicating devices, in contact with tissue and/or bone, with limited contact duration ( ●

The change in the indications for use for the subject device comparted to the master products do not raise new questions of safety related to biocompatibility. There is no change in target populations, target anatomical sites, use environment, user population, category of body contact, body tissue contact, duration of contact, biocompatibility endpoints, type of contact (direct, indirect, or transient).

There is no change in principle of operation, geometry, sterilization process, or manufacturing process between the subject product and the master products that would raise new questions about biocompatibility. There is one new material, two minor changes in material formulation. and changes in manufacturers. Biocompatibility testing was required based on the material changes for the subject product.

The new materials were assembled in a master product configuration and submitted for biocompatibility testing to the endpoints listed above. The results meet the requirements of ISO 10993-1.

Sterilization and Shelf Life

Sterility

Single Use Disposable Components - provided Sterile

The single The Probe Kits are provided sterile and are for single use. Each contains the following basic components:

14

  • o Probe Tip assembly: titanium horn + tip, available in various sizes and types, some are provided with additional fittings, O-rings, stylets, etc.
  • Probe Sheath: rigid plastic or silicone ●
  • Tubing Set: irrigation only or irrigation + aspiration, and tubing "pucks"

These disposable components are supplied in a combined, sterile package, based on the probe tip selected by the customer.

Reusable Components - End User Cleaned and Sterilized

All reusable handpiece parts and accessories are end user cleaned and sterilized before each use as per the validated instructions contained in the Instructions for Use of each Handpiece. The instructions for use also provide the validated expected use life for the reusable components.

Shelf Life

The single use disposable kits have now been tested to support a 37-month shelf life. The results of the accelerated aged testing performed on EtO sterilized test articles and packaging materials demonstrated that the test articles and associated sterile barrier and outer packaging are found to be acceptable for use with a 37-month shelf life.

The single use disposable kits have also been tested to support a 13-month ambient conditions real time shelf life.

Electrical safety and electromagnetic compatibility (EMC)

Electrical safety was conducted on the subject device in accordance with the following standards:

  • IEC 60601-1:2005 (Third Edition) + CORR. 1:2006 + CORR. 2:2007 + A1:2012 ●
  • IEC 60601-2-2: 2017
  • o IEC 60601-1-2:2015

There have been no device modifications related to the wireless communications between the footswitch and the console, therefore the wireless coexistence testing submitted under K190160 remains valid.

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 a "major" level of concern, since a failure or latent flaw in the software could directly result in serious injury or death to the patient or operator.

Bench Testing

The following tests were performed to support the claim of substantial equivalence:

  • Acoustic Intensity Testing .

15

  • Applied Part Temperature Testing - Normal and Abnormal Operating Conditions
  • o Probe Vibration Testing
  • Soft Tissue Performance Testing ●
  • Probe Life Testing ●

Animal Testing

Not applicable. Animal studies are not necessary to establish the substantial equivalence of this device.

Clinical Data

Not applicable. Clinical studies are not necessary to establish the substantial equivalence of this device.

7. CONCLUSION

The substantial equivalence information provided in this submission demonstrates that the subject device is substantially equivalent to the predicate device in both indications for use and technological characteristics. Therefore, the subject device can be found substantially equivalent to the predicate device.
