Disposable tissue-piercing RF electrodes with long injection tubes. Maintain electrode position through placement, injection, stimulation, and RF. Avoid x-raying your hands. Hub markers indicate injection direction.
The ultimate in functionality, precision, and control, the Cosman UnifiedTM (CU) is a disposable, tissue-piercing RF cannula/electrode with a long fluid injection line and thermocouple (TC) temperature sensor. The CUTM is identical to the CR injection electrode with the addition of a TC to enable temperature-controlled RF lesioning. Use for sensitive targets around the spine where it is critical to maintain electrode position during injection and where you desire maximal lesion-size control. The CU's design is unique and protected by U.S. Patent 7,862,563.
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.
Each disposable CP injection electrode has a 1 mm active tip and typically is used for stimulation-guided blocks, in which a nerve stimulation signal is first applied to position the electrode, and then anesthetic solution is injection to block the nerve. Each probe come sterile-packed and is tissue-piecing. Its long, flexible fluid line enables the physican to keep his/her hands out of the x-ray beam while administering contrast medium, and reduces disruption of the needle position during injection.
