Stimulator, Low Electric Field, Tumor Treatment
- Page Type
- Product Code
- Definition
- Intended to treat tumors by application of low electic fields and indicated for treatment of recurrent glioblastoma multiforme (gbm) in patients who have received maximum standard therapy with continued disease progress, as defined by tumor growth or decline in neurological status.
- Physical State
- The device consists of sets of contact electrodes that are applied to the patient's shaved head, a connecting cable and a belt mounted control box and signal generator. The sets are 3 electrodes each adn there can be 2 or 3 sets used at a time.
- Technical Method
- This is a battery powered device. Electric fields that alter thier polarity at a frequency near 200kHz with an intensity near 0.7 V/cm are continuosly applied to the target tumor 24 hours a day for 6 months at a time. This electric field creates, during mitosis process, disruption of the microtubules due to the focussing effect of the narrow neck of the dividing cell.
- Target Area
- The device is currently used only on the human head.

No Linked CFR Text
The FDA has not linked product code NZK to any particular section of the CFR (Code of Federal Regulations). There are multiple reasons why this might be the case:
- The product code was created for a class III submission that does not follow the normal PMN or PMA path - e.g., for a device that falls under HDE (Humanitarian Device Exemption) or EUA (Emergency Use Authorization).
- The FDA has generated the product code for an existing Class III device, as a result of a PMA supplement that modifies the device in a way that it can't fit under the existing product code originally assigned
- The product code was created for internal use at the FDA, and not for classification or regulatory-related purposes.
