No
The iovera system is described as a cryogenic surgical device used to destroy tissue and produce lesions, and for pain relief. Its described function is therapeutic (destroying tissue, blocking pain, relieving symptoms), not diagnostic.
No
The device description explicitly lists hardware components: a reusable Handpiece, a Charging Dock, single-patient-use Smart Tips, and a Cartridge containing nitrous oxide. The performance studies also include testing of these hardware components (Handpiece, Cartridge, Smart Tip, Electrical/EMC safety).
Based on the provided information, the iovera system is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is used to "destroy tissue during surgical procedures by applying freezing cold" and "to produce lesions in peripheral nervous tissue by the application of cold to the selected site for the blocking of pain." It also mentions relief of pain associated with osteoarthritis of the knee. These are all in vivo procedures, meaning they are performed on a living organism (the patient).
- Device Description: The description details a system that applies cold directly to tissue and nervous tissue within the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue samples) to provide information for diagnosis, monitoring, or screening.
IVD devices are specifically designed to be used in vitro (outside the body) to analyze biological samples. The iovera system operates directly on the patient's body.

Device Description
The iovera° system 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 is cooled by the Joule-Thomson Effect and/or latent heat of vaporization.
The device comprises four main components:
- . A reusable Handpiece
- . A Charging Dock
- An assortment of single-patient-use Smart Tips
- . A Cartridge containing 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 contains an LCD display 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° system. All Smart Tip needles are made of stainless steel and have a closed-end design 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° system. The user removes the Smart Tip from its sterile packaging and attaches it to the Handpiece immediately before use.
The iovera° system uses a commercially available nitrous oxide cylinder. The Cartridge is filled with pure N₂O.

ioveraº system
Description of Device: ﻥ
The iovera° system 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 is cooled by the Joule-Thomson Effect and/or latent heat of vaporization.
Device Design
The device comprises four main components:
- . A reusable Handpiece
- . A Charging Dock
- An assortment of single-patient-use Smart Tips
- . A Cartridge containing 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 contains an LCD display 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° system. All Smart Tip needles are made of stainless steel and have a closed-end design 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° system. The user removes the Smart Tip from its sterile packaging and attaches it to the Handpiece immediately before use.
The iovera° system uses a commercially available nitrous oxide cylinder. The Cartridge is filled with pure N₂O.
Device Functionality/Scientific Concepts:
The device functionality is based on the user introducing the Smart Tip into the selected treatment area 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 from the treatment site.
