Intended Use

The Puregraft® 850/PURE 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.

Device Story

Puregraft 850/PURE System is a sterile, single-use, closed-loop system for processing autologous fat tissue. Components include a 1275mL mixing bag with integrated 800-micron and 74-micron filters, a 5L drain bag, tissue access port adapters, and syringe adapters. Used in conjunction with manual instruments (anodized aluminum stand and slider tool). Operation: Adipose tissue is collected into the mixing bag; the slider tool externally compresses the bag to force liquids and debris through the filters into the drain bag, retaining processed fat. The system is used in clinical settings by physicians during cosmetic and reconstructive surgery. Output is processed autologous fat tissue ready for reinjection. Benefits include efficient filtration and transfer of fat tissue for autologous grafting, maintaining a closed system to minimize contamination risk.

Clinical Evidence

No clinical data. Substantial equivalence is supported by nonclinical bench testing, including biological performance verification, tensile strength, pressure, and drop testing.

Technological Characteristics

System consists of PVC bags and tubing, medical grade and DEHP-free. Filtration utilizes 800-micron and 74-micron mesh filters. Manual operation via external slider compression. Sterilized via gamma irradiation. Closed-loop, single-use design.

Indications for Use

Indicated for patients undergoing aesthetic body contouring procedures requiring the harvesting, filtering, and transfer of autologous fat tissue for reinjection into the same patient.

Regulatory Classification

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). Consensus standards and labeling restrictions.

# Puregraft®850 Drain Bag

The Puregraft® 850 Drain Bag is a sterile, single use, 5 liter bag measuring approximately 11," x 8° with a 0.125 inch drain tube measuring 48 inches in length. The drain tube is provided with a pinch clamp on the exterior of the tubing to control the ingress and egress of fluids to and from the Waste Bag. The attached drain tubing contains a luer lock fitting that mates with the male luer lock on the "drain" port of the Puregraft® 850 Bag. All materials are medical grade and DEHP free.

### Luer-Lock Syringe Adapter

The Luer-Lock Syringe Adapter is a sterile, single use, female cylinder measuring approximately 1.5" in length consisting of a swabable luer adaptor on one end and a tapered bore on the opposite end. The swabable female luer mates with a luer-type syringe tip and the tapered bore mates (press fit) with the male end of a Toomey Syringe Adapter and allows for the transfer of material from a Toomey style syringe into a luer style syringe.

#### Tissue Access Port Adapter (TAPA)

The Tissue Access Port Adapter (TAPA) is a sterile, single use, male / female cylinder measuring approximately 1.5" in length and 0.75mm in diameter at the female end and 0.25" on the male end. The female end has a tapered bore of approximately 0.5" and is designed to mate (press fit) with a Toomeystyle irrigation syringe. The male end of the Tissue Access Port Adapter is designed to mate (press fit) with the tapered end of the Luer-Lock Syringe Adapter which allows for the transfer of material from a Toomey style syringe to a luer style syringe. The male end of the Toomey Syringe Adapter is also designed to fit into the Tissue Inlet Port of the Puregraft® 850 Bag which allows for the transfer of tissue from a Toomey style syringe into the Puregraft® 850 Bag.

**Page 4 of 4**

#### EQUIVALENCE TO MARKETED PRODUCT

The Puregraft® 850/PURE System shares indications and design principles with the following predicate device which has been determined by FDA to be substantially equivalent to a premarket device: the Cytori Puregraft® 250/PURE System (K092923); a Class II medical device that has been cleared for marketing in the United States under K092923.

#### Indications for Use

The Puregraft® 850/PURE System and the predicate devices are substantially equivalent with respect to their indications for use, as they are all indicated for the same surgical procedures of harvesting, filtering and transferring of autologous fat tissue for reinjecting back into the same patient.

#### Design and Materials

The design and materials of the Puregraft® 850/PURE System and the predicate device are substantially equivalent, as they are both 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® 850/PURE System is substantially equivalent to the predicate device as they both consist of a polymeric housing chamber with a filter unit within the chamber. The predicate device also shares design principles of accepting adipose tissue from the patient and subsequently transport the adipose tissue through 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. The Puregraft® 850/PURE System is also substantially equivalent to the predicate device as they both have substantially equivalent tissue volume capacities.

#### Nonclinical Summary

As a means to confirm the substantial equivalence between the Puregraft® 250/PURE System and the Puregraft® 850/PURE System, nonclinical testing was performed on the Puregraft® 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® 850/PURE System is substantially equivalent to the Puregraft® 250/PURE System predicate device.
