The LIPOcel delivers High Intensity Focused Ultrasound (HIFU) energy that can disrupt the Subcutaneous Adipose Tissue (SAT) to provide a non-invasive approach to achieve a desired aesthetic effect. The LIPOcel is specifically indicated for non-invasive waist circumference reduction.

LIPOcel, the Subject Device, is a medical device indicated for non-invasive waist circumference reduction. It consists of a control unit, Touch LCD monitor, power supply unit, and driver unit for irradiation and for setting parameters after the main power and key switch is turned on. The ultrasound energy that is generated from the pulse generator operates the HIFU transducer, and is irradiated from the cartridge when the footswitch or the finger switch on the handpiece is pressed in the READY state and the energy is delivered into the target tissue. HIFU energy is irradiated based on linear scanning method through the hand-piece depending on irradiation energy, irradiation spacing and irradiation distance, that are set in advance by the user. The Subject Device's L13 Cartridge uses the focused ultrasound energy to focus from the transducer onto the fat layer at a depth of 13mm from the surface of the skin. As a result, tissue temperature rises over 55°C and thermal coagulation occurs. Using thermal effects generated by the HIFU transducer, cellular disruption of the subcutaneous adipose tissue occurs. This thermal coagulation results in the contraction of the collagen and subsequently results in destruction of the adipose tissue. The destroyed adipose tissue is cleared via an inflammatory response.

1. Table of Acceptance Criteria and Reported Device Performance:

The document describes the device's performance in terms of waist circumference reduction. It does not explicitly state pre-defined acceptance criteria in a quantitative format for the primary effectiveness endpoint (waist circumference reduction). However, it reports the study outcome, which implicitly serves as the performance achieved.
