Clinical Evaluation of Linear Z for Body Contouring

tiistai 1. syyskuuta 2026 päivittänyt: Jeisys Medical Inc

Prospective, Single-center, Single-arm Clinical Research Evaluating the Safety and Effectiveness of Linear Z for Non-invasive Body Contouring of the Abdomen and Flanks

This clinical study will evaluate the safety and effectiveness of LinearZ, a non-invasive focused ultrasound device, for body contouring of the lower abdomen and flanks.

Approximately 30 adults with localized fat in the abdomen and flanks will participate in the study. Each participant will receive one treatment with LinearZ to the lower abdomen and flanks and will be followed for approximately 90 days.

The main purpose of the study is to determine whether treatment with LinearZ reduces the circumference of the treated area 90 days after treatment. The study will also evaluate changes in body circumference at Day 30, changes in body contour and appearance, participant satisfaction, body weight, body mass index (BMI), and body composition. Standardized photographs and three-dimensional images will also be used to assess changes in the treated areas.

The safety and tolerability of the treatment will be evaluated throughout the study by monitoring adverse events and treatment-related pain or discomfort.

Yksityiskohtainen kuvaus

This is a prospective, single-center, single-arm, open-label clinical study designed to evaluate the safety and effectiveness of LinearZ for non-invasive body contouring of the lower abdomen and flanks.

Approximately 30 eligible adult participants with localized, visible, and measurable subcutaneous adiposity of the abdomen and flanks will be enrolled. All eligible participants will receive a single treatment with LinearZ to the lower abdomen and bilateral flanks. There is no randomization or comparator group in this study.

LinearZ is a focused ultrasound device designed to deliver ultrasound energy at specific depths within subcutaneous tissue for non-invasive body contouring. Treatment will be performed according to predefined study procedures and sponsor-approved treatment instructions. Treatment parameters, including the treatment area, cartridge type, treatment depth, energy level, and number of treatment lines or shots, will be documented.

Participants will undergo screening and baseline assessments before treatment and will return for follow-up assessments approximately 30 and 90 days after treatment.

The primary effectiveness assessment is the change from baseline in the circumference of the treated area at Day 90. Circumference measurements will be performed using standardized procedures at predefined anatomical landmarks.

Additional effectiveness assessments include change in circumference at Day 30, aesthetic improvement, participant satisfaction, changes in body weight and body mass index (BMI), and changes in body composition. Standardized clinical photography and three-dimensional imaging will also be used to document and evaluate changes in body contour. Independent blinded evaluators will review standardized images to help minimize assessment bias.

Safety and tolerability will be evaluated throughout the study by monitoring treatment-emergent adverse events, device-related adverse events, serious adverse events, and treatment-related pain or discomfort. Immediate post-treatment skin reactions and other local responses will also be assessed.

Each participant will participate in the study for approximately 90 days from the day of treatment.
