More Information

No
The summary describes a surgical aspirator system that uses ultrasonic technology for tissue fragmentation and aspiration. There is no mention of AI or ML in the intended use, device description, or performance studies. The software testing described is standard verification and validation, not related to AI/ML model training or evaluation.

Yes
The device is described as a surgical aspirator system intended for the fragmentation, emulsification, and aspiration of tissue in various surgical specialties and for wound debridement, which directly addresses medical conditions and aims to restore or improve health.

No

The device is an ultrasonic surgical aspirator intended for the fragmentation, emulsification, and aspiration of tissue during surgical procedures; it is a therapeutic device, not a diagnostic one.

No

The device description clearly outlines hardware components including a console, generator, handpiece, probes, irrigation system, aspiration system, and various accessories. The intended use also describes a system for fragmentation, emulsification, and aspiration of tissue, which requires physical interaction with the body.

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 is for the fragmentation, emulsification, and aspiration of tissue during surgical procedures. This is a direct surgical intervention on the patient's body.
  • Device Description: The device is described as a surgical aspirator system with a generator, handpiece, and probes used to remove tissue from the operative site.
  • Anatomical Site: The listed anatomical sites are all locations within or on the human body where surgery is performed.
  • Intended User / Care Setting: The intended user is a physician in a surgical setting.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. The device's function is to physically remove tissue during surgery, not to analyze biological samples.

Therefore, the Misonix Inc. neXus® Ultrasonic System is a surgical device, not an In Vitro Diagnostic device.

Dear John Salerno:

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. 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 located at https://www.accessdata.fda.gov/scripts/cdrh/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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for

7. PERFORMANCE DATA

Biocompatibility Testing

Not applicable. There have been no modifications related to patient contacting materials, therefore the biocompatibility testing submitted under K221235 remains valid.

18

Electrical safety and electromagnetic compatibility (EMC)

No re-testing required. The change to the neXus console is considered a minor software update only. The safety and performance of the device has been validated and verified through software testing in accordance with IEC62304. There have been no device modifications related to the construction of the console or handpiece, therefore the electrical safety and EMC testing submitted under K221235 remains valid.

Software Verification and Validation Testing

Software verification and validation testing was conducted and a summary of testing provided. The software classification for this device is unchanged as a major level of concern. The following verification tests were conducted:

  • DTC DSP pulse mode verification ●
  • DTC GUI verification ●
  • Fault detection and response test using the SonaStar Elite handpiece ●
  • neXus test and calibration (Regression testing)
  • System performance verification (Regression testing) ●
  • SonaStar Elite GUI verification (Regression testing) ●

Bench Testing

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

  • . Tissue removal test using the SonaStar Elite handpiece
  • DTC mode vibration test using the SonaStar Elite handpiece ●

CONCLUSION 8.

Subject device modifications do not raise new questions of safety or effectiveness. Technological comparison to the predicate and performance testing on the subject device demonstrates substantial equivalence to the predicate device for the requested intended use.
