A pain alleviating tissue treatment assembly uses a combination of a cold electrode and an alterable current source to reduce the temperature of a selected tissue area while at the same, time applying various selected reversing and/or non-reversing currents to the selected tissue. A control console allows the operator to selectively operate the device in conjunction with biological feedback signals and further allows full recordation and/or control of the events as they occur through an attached computer system.

Why it's free to use
- Filed October 27, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 27, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 27, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
