Optimizing Tissue Interaction with Helium Driven Plasma plus Radiofrequency using a Porcine Model




Diane I. Duncan, MD


A study of a helium plasma radiofrequency energy device for the coagulation of subdermal tissue was conducted in a live porcine model. The purpose of the study was to determine the impact of multiple treatment variables on internal and external tissue temperatures with the intent of establishing a range of optimal device settings.

The maximum change in external tissue temperature after 6 passes was less than 4°C, meaning that skin temperature would not go beyond 41°C assuming a starting temperature of 37°C (body temperature). Based on the results of this study, device power settings ranging from 60% to 80% power and a helium flow rate setting of 2LPM was determined to be appropriate due to clinical performance and ease of gas management at these settings.

  • 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 including skin tightening indication referenced in this article.
  • Apyx Medical manufactures and owns the Renuvion/J-Plasma technology discussed in this article.

Risk associated with the use of the Renuvion technology may include unintended burns (deep or superficial), pneumothorax, scars, temporary or permanent nerve injury, pain, discomfort, gas buildup resulting in temporary and transient crepitus or pain, infection, hematoma, seroma; asymmetry and/or unacceptable cosmetic result. There may be additional risks associated with the use of other devices along with Renuvion and there may be an increased risk for patients who have undergone prior surgical or aesthetic procedures in the treatment area. As with any procedure, individual results may vary. 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. Refer to the Instructions for Use for the currently approved or cleared indications.
