Evaluated tissue cluster size (mm²), cell viability, and red blood cell content. Results demonstrated suitable characteristics for intended use and equivalence to predicate. ## Technological Characteristics Closed-loop system; 100mL canister filter; vortex mixer with sterile cover sleeve. Mechanical processing principle; no non-manual energy used for fragmentation. Canister is sterile (SAL 10^-6); mixer is multi-use with single-use sterile cover. ## Regulatory Identification A suction lipoplasty system is a device intended for aesthetic body contouring. The device consists of a powered suction pump (containing a microbial filter on the exhaust and a microbial in-line filter in the connecting tubing between the collection bottle and the safety trap), collection bottle, cannula, and connecting tube. The microbial filters, tubing, collection bottle, and cannula must be capable of being changed between patients. The powered suction pump has a motor with a minimum of 1/3 horsepower, a variable vacuum range from 0 to 29.9 inches of mercury, vacuum control valves to regulate the vacuum with accompanying vacuum gauges, a single or double rotary vane (with or without oil), a single or double diaphragm, a single or double piston, and a safety trap. ## Special Controls *Classification.* Class II (special controls).

DEVICE Name of Device: VorFat System Common or Usual Name: Lipoaspirate Washing System For Aesthetic Body Contouring Classification Name: Suction Lipoplasty System Regulation Number: 21 CFR 878.5040 Regulatory Class: Class II Product Code: QKL Classification Panel: General and Plastic Surgery ## III. PREDICATE DEVICE Primary: The Lipogems System, K171135 / BK220712 ## IV. DEVICE DESCRIPTION The canister with filter (fat canister) of the VorFat System is a closed loop tissue collection system that includes a vacuum port, collection port, tissue port and lid. The canister with filter was previously cleared in K092482. It is used with legally marketed lipoplasty systems to separate, filter, and microfragment adipose tissue for re-injection. As the tissue is harvested from the patient, it enters the collection canister via the collection port in the canister lid. The vacuum port is connected to the standard waste canister, which is connected between the device and the legally marketed lipoplasty system. During harvest, waste is filtered out to the waste canister. After harvest, the collection canister is secured in the adapter attached to the mixer. The mixer applies a mechanical action to the tissue in the collection canister that allows for reduction of the fat cluster sizes. This gentle processing diminishes tissue damage, thereby preserving the cell viability and tissue micro-architecture of the adipose tissue. The product is a micronized fraction of fatty tissue that can be transferred to syringes via the tissue port for autologous fat re-injection. The canister filter is offered in a 100mL size. {1} The subject device VorFat System includes a canister, vortex mixer with canister adapter, and sterile cover for the mixer. The mechanical action of the Subject Device mixer produces a micronized fraction of the adipose tissue, and this technological characteristic is comparable to the predicate device K171135/BK220712. There is no additional non-manual energy delivered to aid in fragmentation of the adipose tissue. ## V. INDICATION FOR USE The VorFat System is intended for the closed-loop processing of lipoaspirate tissue in medical procedures involving the harvesting, concentrating and transferring of autologous adipose tissue harvested with a legally marketed lipoplasty system.

The fat canister is provided in the manufacturer's original packaging with original labeling. | Same | | Operational Principle | Fat is aspirated into a syringe, and transferred to the Lipogems System device, where under constant gravity the fat is mixed with saline and undergoes micronization of the lipidic clusters through a sieve. The unit is shaken while the saline flows through, thus removing oil and blood residuals, and further reducing the clusters. This processing diminishes tissue disaggregation, thus preserving the cell and tissue micro-architecture of the adipose tissue. Finally, the concentrated adipose tissue clusters are passed out of the device into a collecting syringe for transferring back to the patient. | The VorFat System is a closed loop tissue collection system that includes a canister filter (fat canister) and vortex mixer, used with a legally marketed lipoplasty system to separate, filter, and microfragment adipose tissue for autologous reinjection. The canister is connected to a rapid stirrer/vortex mixer. The mechanical mixing action diminishes tissue disaggregation, thus preserving the cell and tissue micro-architecture of the adipose tissue. The result of processing with the VorFat System is a homogenous and micronized fraction of adipose tissue, which allows a patient's subcutaneous fat to be processed for autologous reinjection within the operative procedure time. | Substantially equivalent | | Sterility | Canister: Sterile, SAL 10^{-6} Mixer: Shaken by hand by user | Canister: Sterile, SAL 10^{-6}, purchased from third party, previously cleared Mixer: Non-sterile (covered with sterile sleeve during use) | Same | | Single Use? | Canister: Single Use | Canister: Single Use Mixer: Multi-use Cover sleeve: Single Use | Same | {3} ## VII. PERFORMANCE DATA The following performance data were provided in support of the substantial equivalence determination. ### Bench Testing/Assessment The following evaluations were performed for the VorFat System configuration to demonstrate substantial equivalence: - Tissue Cluster Size Analysis (Adipose Aggregate/Cluster Size in mm²) - Cell Viability - Red Blood Cell Content Both the subject and predicate devices had suitable characteristics for their indication for use. ## VIII. CONCLUSIONS Based on the information contained within this submission, Alma Lasers, Inc. believes that the VorFat System is substantially equivalent to the identified predicate device and does not introduce any new or significantly modified risks, and no new questions of safety and efficacy. --- **Source:** [https://fda.innolitics.com/device/BK220668](https://fda.innolitics.com/device/BK220668) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
