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.

#### DEVICE DESCRIPTION

#### Design Characteristics

The Cytori AFT System is provided in two packaged assemblies: 1). Cytori AFT Tissue Collection Canister and 2). Cytori AFT Delivery Syringe. The Cytori AFT Tissue Collection Canister is a single-use disposable device designed to utilize house vacuum to create suction within the hollow liposuction cannula and remove subcutaneous fatty tissue from the patient and transport the adipose tissue into the collection canister. The Cytori AFT Delivery Syringe is a, sterile, single-use 60cc piston syringe.

#### AFT Tissue Collection Canister

The Cytori AFT Tissue Collection Canister is a sterile, single-use, manual device consisting of a cannula. connection tubing and a tissue collection container that relies on house vacuum for its energy supply. The cannula handle is attached to the tissue collection container via connection tubing. The cannula is a hollow tube with a single opening near the tip to communicate house vacuum to the tissues and subsequently aspirate, harvest and filter subcutaneous fatty tissues from the tissue collection container. The cannula tip is fabricated from medical grade stainless steel and the handle is fabricated from medical grade polypropylene. The connection tubing is fabricated from medical grade polyvinyl chloride (PVC) that is DEHP free. The Collection Canister is fabricated from medical grade polycarbonate to assure robustness in the operating room environment. The tissue collection container contains various capped/sealed luer ports and a 265 micron filter to entrap the tissue while allowing liquid to pass through to a hospital-provided collection trap.

The stainless steel cannula that contacts the patient is provided in various sizes ranging from 15 - 36 cm in length and 3.0 - 4.6 mm in diameter with a single opening near the tip of the cannula. The tip region of the cannula may have a single or multiple openings that range in size from 4 to 12 mm in length distributed uniformly or randomly throughout the end of the cannula. The device is provided with a diameter of 20 mm and may be provided in diameters ranging from 20 to 60 mm. The connecting tubing is provided with an inner diameter of 9.6 mm (3/8"), an outer diameter of 14.3 mm (9/16"), and a wall thickness of 2.2 mm. The tubing that connects the cannula handle to the tissue collection canister is provided in a length of 4 feet and may be provided in lengths ranging from 1 - 8 feet. The bottom of the tissue collection canister is also provided with the same 3/8" inner diameter connection tubing of various lengths. The proximal end of the exiting connection tubing may be provided with a barbed tubing connector to assist in the attachment of like-sized tubing for purposes of connecting the Cytori AFT System to house vacuum and/or assorted waste traps. Connection tubing leading to and from the tissue collection container is provided with a stepped clamp to facilitate manual control of the vacuum supplied to the cannula. The stepped clamps also allow the operator to seal the connection tubing on both sides of the Collection Canister and prevent spillage of the collected fluids/tissues, thereby facilitating safe transport and disposal of the waste materials.

#### AFT Delivery Syringe

The Cytori AFT Delivery Syringe is a polymeric 60cc volume luer-lock style sterile, single-use syringe consisting of a polypropylene barrel with printed graduations, a polypropylene plunger, and a polyisoprene latex free rubber stopper at the end of the plunger.

#### Material Composition

The components of the Cytori AFT System that have direct patient contact are fabricated from surgical stainless steel.

## Sterility

The Cytori AFT System is sterilized by ethylene oxide (EtO) gas.

## In Vitro Testing

Mechanical testing of the Cytori AFT System demonstrates that the device is substantially equivalent to the predicate devices.

## EQUIVALENCE TO MARKETED PRODUCT

The Cytori AFT System shares indications and design principles with the following predicate devices which have been determined by FDA to be substantially equivalent to premarket devices: Shippert Medical Tissu-Trans (K050797), MacroPore Puricel Lipoplasty System (K042261), Exel International Disposable Syringe (K861153) and Genesis Biosystems Lipivage (510(k) number unknown); Class I and II medical devices that were cleared for marketing in the United States under K050797, K042261, and K861153. respectively.

#### Indications for Use

The Cytori AFT 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 aspirating, harvesting, filtering, and transferring autologous tissues.

## Design and Materials

The design and materials of the Cytori AFT System and the predicate devices [Shippert Medical Tissu-Trans (K050797), MacroPore Puricel Lipoplasty System (K042261), Exel International Disposable Syringe (K861153) and Genesis Biosystems Lipivage (510(k) number unknown)] are substantially equivalent, as they are all single-use, polymer constructed, manually operated systems that utilize manual or external sources of vacuum to withdraw, hold, and/or inject fluids/tissues into the body. The Cytori AFT System is substantially equivalent to the Tissu-Trans (K050797), Puricel Lipoplasty System (K042261), and the Lipivage predicate devices, as they all consist of a polycarbonate tissue collection canister with flexible tubing attached to a stainless steel cannula that contacts the patient. The Cytori AFT System is substantially equivalent to the Tissu-Trans (K050797), Puricel Lipoplasty System (K042261), and the Lipivage predicate devices, as they all share design principles of utilizing house-vacuum to aspirate adipose tissue from the patient and subsequently transport the adipose tissue through a tube into a cylindrical collection chamber that contains a filtering mechanism of pores to allow fluids to pass, but retains the adipose tissue within the chamber. The Cytori AFT System is substantially equivalent to the Tissu-Trans (K050797), Puricel Lipoplasty System (K042261), and the Lipivage predicate devices, as they all consist of a polymeric housing chamber with a filter unit within the chamber. The Cytori AFT System is substantially equivalent to the Tissu-Trans (K050797), Puricel Lipoplasty System (K042261), and the Lipivage predicate devices, as they all have connection ports on the superior ends of the housing chamber for the attachment of suction tubing/stainless steel cannulas that contact the patient and connection ports on the inferior end of the housing chamber to connect to vacuum tubing that draws house vacuum and carries waste to the waste trap. The Cytori AFT System is substantially equivalent to the Tissu-Trans (K050797) and the Lipivage predicate devices, as they are all equipped with a separately packaged plunger device to deliver the tissue back to the same patient.
