Intended Use
The iovera? system 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. It is also indicated for the relief of pain and symptoms associated with osteoarthritis of the knee for up to 90 days. The iovera" system is not indicated for treatment of central nervous system tissue. The ioveraº system's "1x90" Smart Tip configuration (indicating one needle which is 90 mm long) can also facilitate target nerve location by conducting electrical nerve stimulation from a separate nerve stimulator.
Device Description
The iovera system is a portable cryogenic surgical device used to destroy tissue and/or produce lesions in nervous tissue creating a nerve block 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 iovera® system 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: 1. A reusable Handpiece 2. A Charging Dock 3. An assortment of single-patient use Smart Tips 4. A Cartridge (Nitrous Oxide)

No
The summary describes a cryogenic surgical device that uses the Joule-Thomson Effect and/or Latent Heat of Vaporization for cooling. It mentions electrical nerve stimulation for targeting but does not describe any AI/ML components or functionalities. The performance studies focus on biocompatibility, software verification (for a "Smart Tip descriptor"), and bench testing of physical properties. There is no mention of training data, test data, or performance metrics typically associated with AI/ML.

Yes.
The device is used to destroy tissue and produce lesions in nervous tissue for pain blocking purposes, and for the relief of pain and symptoms associated with osteoarthritis of the knee, which are therapeutic applications.

No

The device is a surgical device used to destroy tissue and produce lesions, or for pain relief by applying cold, which are all therapeutic actions. While it can facilitate target nerve location by conducting electrical stimulation, this is for guiding the therapeutic procedure, not for diagnosing a condition.

No

The device description explicitly lists hardware components: a reusable Handpiece, a Charging Dock, single-patient use Smart Tips, and a Cartridge (Nitrous Oxide). While software testing is mentioned, the device is fundamentally a hardware system with integrated software.

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... 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 directly on a living organism (the patient).
  • Device Description: The description details a system that applies cold directly to tissue and nervous tissue using a Smart Tip inserted into the body. This is consistent with an in vivo surgical or therapeutic device.
  • 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) outside of the body to provide information for diagnosis, monitoring, or compatibility testing.

IVD devices are specifically designed to perform tests on samples taken from the body, not to directly treat or modify tissue within the body. The iovera system's function is to directly interact with and modify tissue within the patient.

Device Description

The iovera system is a portable cryogenic surgical device used to destroy tissue and/or produce lesions in nervous tissue creating a nerve block 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 iovera® system 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:

  1. A reusable Handpiece
  2. A Charging Dock
  3. An assortment of single-patient use Smart Tips
  4. 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 ioveral system. All Smart Tip 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 ioveras system. The user removes the Smart Tip from the sterile packaging and attaches it to the Handpiece.

The iovera system uses a commercially available nitrous oxide cylinder. The Cartridge is filled with pure N2O.

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 preprogrammed amount of time at which time the user can safely remove the Smart Tip.

Summary of Performance Studies

Biocompatibility Testing:
Biocompatibility testing was conducted on the new Smart Tip needle in accordance with ISO-10993, ‘Biological Evaluation of Medical Devices, Part 1: Evaluation and Testing" as recognized by FDA. The battery of testing included the following test: Cytotoxicity Sensitization Intracutaneous Reactivity Acute System Toxicity Material-Mediated Pyrogenicity.

Software Testing:
Software verification testing for the new Smart Tip descriptor was conducted as recommended by FDA's Guidance document, “Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices” in conjunction with bench testing of the Smart Tip (see below). No other software changes were required for this submission.

Bench Testing:
Bench testing was performed on the new Smart Tip to demonstrate that the product met the design requirements. A risk analysis was used to assess the impact of the modification, as well, and design verification testing was performed as a result of this risk analysis assessment. In all cases, the risk was mitigated to acceptable levels and the performance testing demonstrated that the Smart Tip design is in compliance with pertinent standards. Specifically, the following tests were performed:

  • Electrical Safety Testing per IEC 60601-1: PASS
