The Smart Kit is disposable and is indicated for autologous fat transfer is also technically called as autologous fat grafting or reinjection of concentrated adipose-tissue into the recipient body areas. The Smart kit can be used for concentration and transfer of homogenous adipose tissues with legally marketed lipoplasty system when the concentrated and homogenous fat tissue is re-injected into the recipient body areas of the same patient autologously. This device is intended for autologous fat transfer. The Smart Kit is intended for use in the following surgical specialties when the concentration of harvested adipose tissue is desired. Neurosurgery / Gastrointestinal Surgery / General surgery / Orthopedic Surgery / Gynecological Surgery / Thoracic Surgery / Laparoscopic Surgery / Arthroscopic Surgery / Plastic and reconstructive surgery
The fat harvested by liposuction, called as lipoaspirates, contains fat tissues, bloody impurities and tumescent solution. The harvested lipoaspirates are not appropriate for autologous fat transfer without removal of the bloody impurities and tumescent solution containing anesthetic agent, anti-coagulant agent, antibiotics and etc. In addition, the harvested fat tissues are not homogeneous and contain bigger fibrotic tissues. Smart kit is designed and developed for harvest of a variety of sizes of homogeneous adipose tissues in a closed sterile way for autologous fat transfer surgical technique. Using a separate cannula, Manual handheld suction unit, and plunger, aspirate the adipose tissue or fill the syringe with adipose tissue and centrifuge with the cap in front of the syringe. Centrifuged adipose tissue is divided into blood and fluid layer, adipose tissue layer, and free oil layer. Those are located at the bottom of the piston. After centrifugation, the plunger is pushed unlocked to the piston and free oil is drained to the outside of the syringe as the free oil moves to the top of the piston through the hole at the front of the piston. Open the cap in front of the syringe, lock the plunger completely and push it, the blood and fluid layers at the bottom of the adipose tissue will be drained and only the adipose tissue will remain inside the syringe. Depending on the syringe capacity, there are three types of piston: 10ml, 20ml, 60ml. The built-in filter adapter consists of a filter for separating the fiber and adipose tissue to facilitate movement through needles of lumpy adipose tissues and a body for receiving it. Connect the syringe containing the adipose tissue and the empty syringe to the connection parts at both ends of the built-in filter adapter and push the plunger of the syringe containing the adipose tissue to allow the adipose tissue to pass through the filter. Fiber and adipose tissues larger than the pore size is filtered, and adipose tissue smaller than the pore size of the filter is passed through to separate adipose tissue.
The provided text describes a medical device called "Smart Kit" and its performance testing for FDA 510(k) clearance, asserting its substantial equivalence to a predicate device. However, the document does not contain details of a study proving the device meets acceptance criteria related to a specific AI algorithm or its performance in a clinical setting.
The "Performance Testing" section focuses on physical and chemical properties of the device itself (e.g., appearance, water tightness, material compatibility, sterilization). The "Cell Viability Test" is the most relevant performance metric that could be interpreted as a clinical outcome, but it is a general statement about maintaining cell viability for autologous fat transfer.
Therefore, most of the requested information about AI model performance, sample sizes for test/training sets, expert adjudication, MRMC studies, and standalone AI performance cannot be extracted from this document, as it describes a physical medical device, not an AI algorithm.
Below is a table of acceptance criteria and reported device performance from the document. The remaining requested information is largely not applicable or not provided in the context of this device's clearance.

2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample size for the "bench tests." The tests listed are primarily physical, chemical, and biological characterization tests performed on the device itself or its materials, rather than a clinical human subject test set. The data provenance is not specified, but these are laboratory tests rather than patient data.
3. Number of Experts Used to Establish Ground Truth and Their Qualifications
Since the tests performed are bench tests (biocompatibility, mechanical, sterility, extraction, cell counts/viability), the concept of "ground truth" established by human experts in a diagnostic or clinical context is not applicable. The ground truth for these tests is based on objective laboratory measurements and established scientific standards (e.g., ISO guidelines, ASTM standards, chemical analysis techniques).
4. Adjudication Method for the Test Set
Adjudication methods like "2+1" or "3+1" are relevant for clinical studies where human interpretation of medical images or outcomes needs consensus. For the bench tests described, adjudication is not applicable. The "results" are objective measurements.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC comparative effectiveness study was done. The document describes bench testing to demonstrate functionality and substantial equivalence to a predicate device, not a human reader study.
6. Standalone (Algorithm Only) Performance Study
Not applicable. This device is an Automatic Tissue Processing Unit, a mechanical/biological processing system, not an AI algorithm.
7. Type of Ground Truth Used
The "ground truth" for the performance data in this submission consists of:
- Objective physical measurements: Dimensions, leakage, adhesive strength.
- Chemical analysis results: Residuals of cleaning liquid, pH, KMnO4 reducing agents, evaporating residue, heavy metals, UV-vis spectrum.
- Biological assay results: Nucleated cell count and viability.
- Standardized biological test outcomes: Biocompatibility tests (cytotoxicity, sensitization, systemic toxicity, pyrogenicity, hemolysis) performed according to ISO standards, where "Pass" is the objective outcome based on the standard's criteria.
8. Sample Size for the Training Set
Not applicable. This device is not an AI/ML algorithm that requires a training set. The data presented is for validation and verification of the physical device's performance.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this type of device.
