Cosman CC/RFK Cannula

Radiofrequency (RF) cannulae designed for easy and precise placement on the nerve to be treated. such as a painful spinal nerve. The cannula is placed percutaneously and an RF electrode is placed together with it to supply the RF energy to the tissue to be treated and measure its temperature. These cannulae are smooth manageable and cost-effective use with thermocouple electrodes (TC). The insulation of each cannula is thinner at the tip for easy insertion and manoeuvre, additionally the echogenic version improves the visibility of the tip in ultrasound images. They are available in all sizes and shapes used for the treatment of pain.

Characteristics

  • Smooth manageable and affordable RF cannulae for use with thermocouple electrodes (TCD).
  • The widest range of cannulae on the market, with several sizes available for the best therapeutic use:
    • Active tip: 2 mm, 4 mm, 5 mm, 10 mm, 15 mm.
    • Length: 5 cm, 10 cm, 15 cm and 20 cm.
    • Thickness: 23G, 22G, 21G, 20G, and 18 G.
  • Two active tip shapes available: straight or curved (CC/RFK).
  • Two types of active tip:sherp or blunt.
  • Possibility of improved echogenic version (EchoRF ™).
  • Design in the shape of an ergonomic cube, with rigid directional axis and specific tapered isolation in the tip to facilitate insertion and manoeuvres.
  • Colour coding for easy identification of each cannula with the corresponding electrode.
  • Colour correspondence and compatibility of the cannulae with all Cosman electrodes of the same length, including the re-useable stainless steel (CSK) and disposable (TCD) model.
  • Easily extractable guide in the CC/RFK versions in order to be able to insert the suitably-sized temperature detector electrode (standard or disposable).

Specifications

  • Easy withdrawal and placement stylet and electrode for greater precision during the intervention.
  • Clear fluoroscopic/ultrasound views: cannulae with a very visible compact design and another echogenic option for use with ultrasound.
  • Habitual use in RF techniques, both thermal and pulsed, on nerve structures around the spinal cord, both at a lumbar-sacral and cervical level.
  • The most common interventions at a spinal level are: Thermal RF of the Medial Ramus, Pulsed RF of the DRG, sympathectomy etc.
  • The most common interventions on peripheral nerves are: Pulsed RF of the supraescapular, splanchnic, calcaneus, knee (geniculate and intra-articular), peroneal, gluteal, tibial nerves etc.
  • Common use in trigeminal neuralgia (with reference CC-10222 designed specifically for this intervention).
  • Its light design and internal cavity enable the injection of anaesthetics, corticosteroids, contrast and other fluids via the cannula for localised treatment.
