No
The device description details a mechanical filtration system with no mention of software, algorithms, or data processing that would indicate AI/ML. The performance studies focus on mechanical and biological equivalence to predicate devices.
No
The device is described as a system for harvesting, filtering, and transferring autologous fat tissue. Its function is to prepare the fat tissue for reinjection for aesthetic body contouring, rather than directly treating a disease or condition.
No
The device is described as a system for harvesting, filtering, and transferring autologous fat tissue for aesthetic body contouring. Its purpose is to prepare fat grafts, not to diagnose a condition.
No
The device description clearly outlines multiple physical components (filters, bags, ports, slider) and describes a mechanical process for filtering fat tissue. There is no mention of software as a component or function of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "harvesting, filtering and transferring of autologous fat tissue for reinjecting back into the same patient for aesthetic body contouring." This describes a process performed on tissue outside the body, but the purpose is for reimplantation into the same patient, not for diagnostic testing of the tissue itself.
- Device Description: The device is a system for processing fat tissue. It involves filtration and transfer, which are physical manipulations of the tissue. It does not describe any components or processes related to analyzing biological samples for diagnostic purposes (e.g., detecting markers, analyzing cellular components for disease).
- Lack of Diagnostic Elements: There is no mention of analyzing the fat tissue for any diagnostic information, such as disease markers, cellular abnormalities, or other indicators of a patient's health status.
- Focus on Body Contouring: The primary indication is "aesthetic body contouring," which is a therapeutic or cosmetic procedure, not a diagnostic one.
IVD devices are specifically designed to examine specimens derived from the human body (like blood, urine, tissue) to provide information for the diagnosis, monitoring, or treatment of a disease or condition. This device's function is to prepare tissue for reimplantation, not to diagnose anything from the tissue.

Device Description
The Puregraft 50 System is a sterile, single use, closed system intended for the preparation and delivery of autologous fat grafts back to the same patient for aesthetic body contouring in cosmetic and reconstructive surgery applications. The dual filtration bag system connects to an off the shelf sterile luer lock syringe through a swabable luer activated valves interface. The attached slider is used to facilitate the movement of liquids through the filter mesh and out of the Puregraft bag through the drain stub as waste.
The Puregraft 50 System is composed of the following components:
- Outer Membrane: 2
- Filter 74 micron: 1
- Filter 800 micron: 1
- Tissue Port: 1
- Drain Port: 1
- Attached Slider: 1
The Puregraft 50mL System is a sterile, single-use, 100mL capacity mixing bag measuring approximately 184 mm x 96 mm and consists of 2 filters layered between a polyvinyl chloride (PVC) outer shell and 2 ports on the bottom of the bag. Each port is labeled and designed to assure the proper connection is made with a luer fitting. The "tissue" port and the "drain" port contains a female swabable luer fitting designed to connect to a luer syringe. The "tissue" port and the "drain" port are designed as one-way valves to assure that the contents within the Puregraft 50mL Bag are not accidently spilled from the bag. The Puregraft 50mL Bag contains two (2) filters that are continuous within the bag. The first filter is a 800 micron filter mesh and the second filter is a 74 micron filter. The Puregraft 50 Bag has an attached plastic "slider" that is used to compress the Puregraft bag as a means to facilitate the movement of liquids through the filter mesh and out of the Puregraft bag to waste; through the "drain" port. All materials are medical grade and DEHP free.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Nonclinical testing was performed on the Puregraft 50 System in addition to the 850/PURE System and Puregraft 250/PURE System predicate device that included biological performance verification and bench-top testing such as tensile strength, pressure, and drop testing.

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 of1/3 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.(b)

EQUIVALENCE TO MARKETED PRODUCT
The Puregraft 50 System shares indications and design principles with the following predicate devices which have been determined by FDA to be substantially equivalent to a precardaet device: the Cytori Puregraft® 250/PURE System (K092923), and Puregraft 850/PURE System (K113255); both are a Class II medical device that have been cleared for marketing in the United States under K092923 and K113255 respectively.
Indications for Use
The Puregraft 50 System and the predicate devices are substantially equivalent as they share identical indications for use language and they are all indicated for the same surgical procedures of harvesting, filtering, and transferring autologous tissues for reinjecting back into the same patient for body contouring. The Puregraft 50 System's indications for use are identical to the cleared indications for use of the predicate devices. Specifically, the Cytori Puregraft 50 System is indicated for:
The Cytori Puregraft 50 System is indicated for use in the harvesting, filtering and transferring of autologous fat tissue for reinjecting back into the same patient for aesthetic body contouring.
Design and Materials
The design and materials of the Puregraft 50 System and the Puregraft 250/PURE System (K092923) and Puregraft 850/PURE System (K113255) are substantially equivalent as thy are all single-use, polymer constructed, manually operated systems that receive adipose tissue, filter the adipose tissue, and temporarily hold the adipose tissue until it is removed or placed into a syringe that delivers / re-injects the adipose tissue back into the same patient during the same surgical procedure. The Puregraft 50 System is substantially equivalent to the predicate devices as they are all constructed of a polymeric flexible housing bag with a filter unit within the bag and ports to accept and remove the tissue with a syringe. These predicate devices also share design principles of accepting adipose tissue from the patient and subsequently transport the adipose tissue through a tube into a polymeric collection chamber/bag that contains a filtering mechanism of various pore sizes that restricts the movement of adipose tissue and only allows fluids and small debris to pass through the filter and become deposited into a waste container.
Mechanical and Nonclinical Testing Summary
As a means to confirm the substantial equivalence between the Puregraft 50 System, the Puregraft 250/PURE System Puregraft 850/PURE System, nonclinical testing was performed on the Puregraft 50 System in addition to the 850/PURE System and Puregraft 250/PURE System predicate device that included biological performance verification and bench-top testing such as tensile strength, pressure, and drop testing. The nonclinical testing demonstrates that the Puregraft 50 System is substantially equivalent to the Puregraft 250/PURE System and Puregraft 850/PURE System predicate devices.
