Braun Medial Inc. 0.22 Micron Flat Epidural Filter # Device Description: The Portex® Epidural Filter is a 0.2um (micron) filter used in epidural anesthesia for the filtration of aqueous drugs and is designed to help protect the patient from injected microorganisms or particulate matter. The Filter is comprised of a 0.2 um supported membrane enclosed in a modified acrylic leak proof transparent housing with male Lucr with a rotating Locking Hub and a female Luer Lock. The filtration area is 5.25 cm², has a flow rate of ≥ 200ml/Min @ 45 psi and can withstand a pressure of ≥ 115 psi during bolus injections. The priming volume of the filter is 0.8 ml and the hold up volume is 0.45 ml as determined by weight. The filter has a bubble point of ≥46psi. The filter has 100% bacterial retention. ### Indications for Use: An anesthesia conduction filter is a microporous filter used while administering to a patient injections of local anesthetics to minimize particulate (foreign material) contamination of the injected fluid. {1}------------------------------------------------ #### Technological Characteristics: The design of the proposed filter is similar to the predicate device. Both are a round flat filter with male and female Lucr lock fittings. Both of the devices are a hydrophilic membrane enclosed in a plastic housing. The proposed is comprised of a 0.2micron filter and the predicate of a 0.22 micron filter. All statements and representations set forth herein regarding or related to "substantially equivalent" or "substantial equivalence" are in the limited context of the definition and purpose of substantial equivalence in the Federal Food, Drug, and Cosmetic Act, as amended, and applicable regulations of the Food and Drug Administration, and are not made in the context of, for any purpose related to, or as an admission against interest under, any other laws or regulations, including patent laws (whether in the context of patent infringement or otherwise). #### Non-Clinical Data: Data submitted demonstrates that the epidural filter performs equivalently to the predicate device. Data submitted covers; dimensional characteristics, flow rate, bubble point, ISO 594-1 and ISO 594-2 testing and bacterial retention, #### Clinical Data: Not required. #### Conclusion: The proposed device is safe and effective and is substantially equivalent to the predicate device.
