Introduction: Renuvion was the first FDA approved helium plasma device utilized for subdermal tissue heating to reduce skin laxity. The purpose of this study was to demonstrate that the use of Renuvion improves the outcomes, skin quality and reduces the edema faster after lipoabdominoplasty.
Materials And Methods: Patients with abdominal skin laxity after a weight loss of at least 20 kg, nonsmokers, without major comorbidities, with a minimum 2-year follow-up and standardized pre- and postoperative photographs were included in this study.

Thighplasty is a widely performed body contouring procedure, utilizing various surgical techniques for thigh lifting, including medial scar positioning, vertical and horizontal procedures, and liposuction. Despite its popularity, thighplasty is associated with high complication rates and suboptimal postoperative outcomes.This article presents a novel technique: the J medial thighplasty combined with helium plasma radiofrequency technology (HPRF) to address moderate skin and soft-tissue laxity and ptosis in the inner thighs.

This study explores the effects of different passivation gases on the properties of polymers formed on aluminum (Al) sidewalls during the etching process in Al-based interconnect structures. The research compares the use of nitrogen (N) and ethylene diluted with helium (CH/He) as passivation gases, focusing on the resulting polymer's composition, thickness, and strength, as well as the levels of residual chlorine post-etch. The findings reveal that using CH leads to the formation of a thinner, weaker polymer with lower chlorine residue compared to the thicker, stronger polymer formed with N.

Under various atmospheric conditions, laser-induced breakdown spectroscopy (LIBS) is a powerful technique for elemental analysis, including in Earth- and Mars-like environments. However, understanding the plasma behavior and its dependence on ambient pressure and laser parameters remains a challenge. In this study, a numerical model based on a three-temperature Eulerian radiation framework under non-local thermodynamic equilibrium conditions is employed to investigate the interaction of a nanosecond laser pulse with a graphite target under helium (He) and carbon dioxide (CO atmospheres.

Background: Application of helium-based plasma radiofrequency (RF; Renuvion, Apyx Medical, Clearwater, FL) in the subcutaneous plane results in tissue coagulation and contraction. Although, traditionally, the impact of thermal devices on skin laxity is assessed by measuring changes in skin surface area, this indirect measure does not permit intraoperative assessment or differentiation of effects from various treatments.
Objectives: To determine the amount of soft tissue contraction achieved by multiple passes of helium plasma RF energy to the subcutaneous connective tissues following power-assisted liposuction (PAL).
