Model N40 adds: Skeletal Muscle Mass; Actual: Weight, BMI, Impedance Values ## Device Story SLIMMANAGER (Models N40, SM-300) is a body composition analyzer using Bioelectrical Impedance Analysis (BIA). Device sends weak electric current through body; detects impedance response based on water content in muscle/cellular fluids versus fat/bone tissues. Transforms impedance data into estimates of lean tissue, fat, and water mass. N40 features integrated Linux system with touch monitor; SM-300 interfaces with external PC. Used by individuals for self-monitoring; measurements saved locally or transmitted via Internet to personal web page for progress tracking without expert intervention. Output provides users with body composition metrics to monitor health changes over time. ## Clinical Evidence Bench and clinical testing performed. Results indicate device is as safe and effective as predicate devices. No specific clinical trial metrics (e.g., sensitivity, specificity) provided in summary. ## Technological Characteristics BIA technology; 8-electrode tactile configuration. N40: Linux-based with touch monitor. SM-300: PC-interfaced. Power: AC100-120/200-240V. Connectivity: Internet transmission for web-based data storage. Measuring scope: 1-200kg (N40), 1-150kg (SM-300). ## Regulatory Identification An impedance plethysmograph is a device used to estimate peripheral blood flow by measuring electrical impedance changes in a region of the body such as the arms and legs. ## Special Controls *Classification.* Class II (special controls). The device, when it is a body composition analyzer which is not intended to diagnose or treat any medical condition, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9. ## Predicate Devices - Biospace InBody 230 ([K062603](/device/K062603.md)) - AIIA communication Inc.

SLIMMANAGER(SM-X, SM-E) K051589 - 3. Indications for Use (intended use) (Models SM-300 and N40) For Measurement in healthy subjects of: Estimated : ECW, ICW, TBW, ECW/TBW, Body Fat, Body Lean +Dry Lean Metabolic Rates, Segmental Lean Mass. Model N40 adds: Skeletal Muscle Mass; Actual: Weight, BMI, Impedance Values - 4. Description of the Device: SLIMMANAGER is a body composition analyzer and uses Bioelectrical Impedance Analysis technology to determine body composition parameters. Using a principle that an electric current has a low impedance when it flows in muscle or cellular fluids containing lots of water while it has a high impedance such as in fat and bone tissues slowing and stopping an applied current, BIA sends an extremely weak electric current through the body and detects the relative response after it flows our body's various substances, and then it can determines lean tissue, fat, water mass. All measurements made by SLIMMANAGER can be recorded & saved in the website real-time by the Internet transmission as well in the device, and in his own page people could check their changing progress even a minute change without an expert's advice at anywhere, at anytime. N-40 is designed by Linux system with touch monitor, while SM-300 should be interfaced with customer's PC. - 5. Safety and Effectiveness, comparison to predicate device. The results of bench and clinical testing indicates that the new device is as safe and effective as the predicate devices. {1}------------------------------------------------ Image /page/1/Picture/0 description: The image shows the text "K073227 PAGE 2 OF 2".
