Herein we report nine cases of carotid endarterectomy in which we used a cold atmospheric helium plasma device (J-Plasma). Although clinical reports are limited, experimental data indicate that this technology could be used for dissection and coagulation during surgery, yielding limited adjacent tissue damage. As a result, it could be extremely useful in procedures like carotid endarterectomy that necessitate careful dissection and coagulation with limited damage of adjacent neurovascular structures.

  • Apyx Medical wants to present you with current scientific discourse. Specific usage outside of the general cleared indication may not be safe or effective. Renuvion®/J- Plasma has received a general clearance and has not been determined to be safe or effective for use in any specific indication or anatomical location.
  • Apyx Medical manufactures and owns the Renuvion/J-Plasma technology discussed in this article.

Risks associated with the use of J-Plasma may include: Helium embolism due to insufflation of gas into the surgical site or due to inadvertent introduction into the venous or arterial blood supply system; ineffective hemostasis; infection of the treatment site post-treatment; unintended injury (burn, scarring, increased healing time) due to excessive treatment; pneumothorax, hematoma, pain, erythema, edema, or bleeding. As with all energy devices there are inherent risks associated with its use, refer to the IFU for further information.

The Renuvion/J-Plasma Precise Open® Handpiece is intended to be used with compatible J-Plasma electrosurgical generators for the delivery of radiofrequency energy and/or helium plasma for cutting, coagulation and ablation of soft tissue during open surgical procedures. The Renuvion/J-Plasma Precise & Precise Open Handpieces are compatible with electrosurgical Generators BVX-200H, and BVX-200P.
