RF Injection Electrodes (CR)

Each disposable CR injection electrode has a 5 mm active tip and typically is used for non-temperature-controlled radiofrequency (RF) facet denervations.  Each probe comes sterile-packed and is tissue-piecing to eliminate the need for introducer cannulae.  Its long, flexible fluid line enables the physican to keep his/her hands out of the x-ray beam while administering contrast medium or anesthetic, and reduces disruption of the needle position during injection.

The CR electrode has a discrete, ergonomic hub for clear fluoroscopic views and comfortable handling.  A marker on the hub indicates the orientation of the bevel opening of the 5 mm active tip. A variety of shaft lengths are available for targeting nerves in different parts of the spine:

  • 6 cm
  • 10 cm
  • 15 cm

The CR injection electrode has a shrouded connector for safe electrical connection to a radiofrequency generator.  A variety of cabling options are available:

  • Single cable (CB116): A ~3-meter cable connects an single CR electrode to the output jack of an RF generator
  • Splitter cable (CB116-4): A ~3-meter cable connects an four CR electrodes to a single output jack of an RF generator

A variety of cable organizaton option are available for use with the CR injection electrodes:

  • The CR cable organizer (CR-CO) keeps the electrical and injection lines of up to six CR needles untwisted and ordered during a procedure.  The organizer can be sterilized and clipped to the surgical drapes, and CR needles attached to pins on one side of the CR-CO. When it is desired to lesion on one CR at a time, the electical cable from the generator can be easily moved between pins on the other side of the organizer to electrify each CR electrode in turn.  When it is desired to lesion multiple CR electrodes at a time, multiple cables from the G4 four-output radiofrequency generator can be connected to the organizer.
  • The G4 cable organizer (G4-CO) keeps the CB116 ~3-meter organzied as the run from the G4 four-electrode RF generator to the surgical field where they are each connected the electrical line of a CR injection electrode.

When temperature control is desired for more sensitive targets, consider using the CU disposable injeciton electrode. The CU is identical to the CR with the addition of a TC temperature sensor.
