What is it indicated for?
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.
When stimulation compatible components are used , the iovera® System can also facilitate target nerve location by conducting electrical nerve stimulation from a compatible 3rd party nerve stimulator.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
