The Lipipor Infusion Filters are indicated for the removal of inadvertent particulate debris and microbial contaminants larger than 1.2 μm and entrained air which may be found in intravenous solutions, parenteral nutrition admixtures, and injectable lipid emulsions. They are also indicated for the removal of inadvertent enlarged lipid droplets from parenteral nutrition admixtures and injectable lipid emulsions. # Device Description The Lipipor NLF1A and TNA2A Infusion Filters are available in one model each. The Lipipor NLF2A Infusion Filter is available in two models, one for use when additional tubing from the filter to the patient is preferred (NLF2A), and the other for use when the additional extension tubing is not needed (NLF2NTA). All of the subject filters are disposable filters for infusion solutions that are comprised of the following components, with minor variations as outlined below: - Filter housing - holds the filtering elements comprised of a 1.2 μm Supor (Polyethersulfone) hydrophilic membrane and Polytetrafluorethylene/polyester air elimination membrane. o In the NLF2A variant, the NLF2A filter housing has microbore tubing at the exit or downstream Page | 1 {5} K261403_510K Summary port and a molded input port that permits connection using a female luer connector; the NLF2NTA filter housing has a male luer connector at the exit or downstream port and a molded input port that permits connection using a female luer connector. - Female luer connector - provides connection to the tubing that is connected to the packaging that holds the infusion solution. - Microbore tubing - one section of tubing connects the filter housing to the male luer connector and retains the tubing clamp; the other connects the female luer connector to the filter housing. - Tubing clamp - provides a method to stop the flow of the infusion solution to the patient; o The NLF2NTA Infusion Filter is not supplied with microbore tubing or a tubing clamp. - Male luer connector - provides connection to the medical device in contact with the patient. ### Comparison of Technological Characteristics with the Predicate Device The subject and predicate devices have the same fundamental design, consisting of the filter media and housing along with associated connection tubing/hardware. In addition, the subject and predicate filters operate based on the principle of size exclusion, also known as direct interception filtration, where particles larger than the pore size of the filter's hydrophilic membrane (1.2 μm) are retained and do not proceed with the solution to the patient. The main technological differences between the subject Lipipor Infusion Filters and the predicate device are: - The device housing sizes and effective filtration areas; - The holdup volumes (resulting from the differences in filter housing sizes); - The membrane material is polyethersulfone, versus polyamide (nylon) in the predicate; - The maximum operating pressures are higher in the subject filters. - A table comparing the key features of the subject and predicate devices is provided below. | | Subject Devices | | | Predicate Device | Comparison | | --- | --- | --- | --- | --- | --- | | Element | NLF1A Infusion Filter | NLF2A & NLF2NTA Infusion Filters | TNA2A Infusion Filter | 3N1 (TNA1) Intralipid filter (K905794) | | | Indications for Use | The Lipipor NLF1A, NLF2A, NLF2NTA, and TNA2A Infusion Filters are intended for use within the healthcare environment such as hospitals, healthcare facilities or clinical settings for infusion line filtering.

The minor differences in indications do not alter the intended therapeutic use, nor do they affect the subject devices' safety and effectiveness when used as labeled. In addition, the minor technological differences between the devices raise no new questions of safety or effectiveness. Performance data further support that the subject devices are as safe and as effective as the predicate. Thus, the subject filters are substantially equivalent to the previously cleared predicate device.
