The description focuses on the cryogenic mechanism and preprogrammed parameters in the Smart Tip, with no mention of AI or ML algorithms for decision-making, image analysis, or adaptive control.
Yes.
The device is used to destroy tissue and produce lesions to block pain, which are therapeutic actions.
No
The device is described as a surgical device used to destroy tissue and produce lesions by applying freezing cold, or to block pain. Its function is to treat or alter tissue, not to diagnose conditions.
No
The device description clearly outlines multiple hardware components including a handpiece, charging dock, smart tip, and nitrous oxide cartridge. It is a physical device that uses cryogenic fluid to destroy tissue.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "destroy tissue during surgical procedures by applying freezing cold" and "produce lesions in peripheral nervous tissue by the selected site for the blocking of pain." This describes a therapeutic or surgical intervention performed directly on the patient's body.
- Device Description: The device description details a portable cryogenic surgical device that applies cold to tissue. This is consistent with a surgical tool, not a device used to examine specimens outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) in vitro (outside the body) to diagnose a condition, monitor treatment, or screen for diseases.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. This device's function is to directly modify tissue within the body.

Intended Use / Indications for Use
The myoscience iovera® device is used to destroy tissue during surgical procedures by applying freezing cold. It can also be used to produce lesions in peripheral nervous tissue by the selected site for the blocking of pain. The iovera® device is not indicated for treatment of central nervous system tissue.

Device Description
The myoscience iovera® device is a portable cryogenic surgical device used to destroy tissue and/or produce lesions in nervous tissue through application of extreme cold to the selected site. The device is based on introduction of a Smart Tip internally cooled by the cryogenic fluid (nitrous oxide, N2O) to a selected area. The Smart Tip has the added functionality of having the treatment parameters being preprogrammed into its secure processor. The Smart Tip is cooled by the Joule-Thomson Effect and/or Latent Heat of Vaporization. The iovera® device may be used in conjunction with a standard off-the-shelf nerve stimulator device in applications where precise nerve location is desired.
The device is comprised of four main components:
- A reusable Handpiece
- A Charging Dock
- A single-patient use Smart Tip
- A Cartridge (Nitrous Oxide)
The iovera® Handpiece is battery powered and provides feedback to the user during device preparation and use. The Handpiece connects to both the Cartridge and to the Smart Tip. The user activates a treatment cycle through a control on the Handpiece, which starts and stops the treatment. The Handpiece also contains LEDs for providing feedback to the user when the device is ready to use. The Charging Dock stores the Handpiece between uses and provides power for charging the battery.
An assortment of Smart Tips is available for the iovera® device. All Smart Tips needles are made of stainless steel and have a closed-end that fully contains the cryogen so that it does not enter the target tissue. The Smart Tip is the only patient contacting component of the iovera® device. The user removes the Smart Tip from the sterile packaging and attaches it to the Handpiece.
The iovera® device uses a commercially available nitrous oxide cylinder (N2O). The Cartridge is filled with pure N2O.

The Handpiece also contains LEDs for providing feedback to the user when the device is ready to use. The Charging Dock stores the Handpiece between uses and provides power for charging the battery.
An assortment of Smart Tips is available for the iovera® device.

The Smart Tip is the only patient contacting component of the iovera® device. The user removes the Smart Tip from the sterile packaging and attaches it to the Handpiece.
The iovera® device uses a commercially available nitrous oxide cylinder (N2O). The Cartridge is filled with pure N2O.
Device Functionality/Scientific Concepts
2
The device functionality is based on the user introducing the Smart Tip to the selected treatment area: unwanted tissue or the target nervous tissue. The user then initiates the flow of cryogen by pressing the on/off button. Liquid cryogen flows from the Handpiece into the closed-end Smart Tip. The Smart Tip is cooled by the Joule-Thomson Effect and/or Latent Heat of Vaporization; as the liquid cryogen expands into a gas, the temperature drops around the external surface of the Smart Tip causing the surrounding tissue to freeze. The treatment is completed after a pre-programmed amount of time at which time the user can safely remove the Smart Tip.
d. Intended Use
The myoscience iovera® device is used to destroy tissue during surgical procedures by applying freezing cold. It can also be used to produce lesions in peripheral nervous tissue by the application of cold to the selected site for the blocking of pain. The iovera® device is not indicated for treatment of central nervous system tissue.
e. Comparison to Predicate Devices
The myoscience iovera® device is substantially equivalent in intended use, technology, design and materials to the above listed legally marketed predicate device.

Dear Mr. Chandran:
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. 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
