The circuit connects the anesthesia gas machine to the patient by means of an oronasal face mask or by a connection to an artificial airway, such as an endotracheal tube. In the case of the Zefon circuit, a heat moisture exchange filter is included to minimize viral and bacterial contamination of the inspiratory and expiratory limbs of the circuit. ## Device Story Zefon Anesthesia Circuit with Bacterial Filter facilitates delivery of medical gases from anesthesia machine to patient. Device connects to patient via oronasal face mask or artificial airway (endotracheal tube). Integrated heat moisture exchange (HME) filter minimizes viral and bacterial contamination within inspiratory and expiratory limbs of circuit. Used in clinical anesthesia settings by healthcare professionals. Benefits include gas delivery and reduction of cross-contamination risk. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Anesthesia circuit assembly including integrated heat moisture exchange (HME) bacterial filter. Designed for connection between anesthesia gas machine and patient airway interfaces (mask/endotracheal tube). ## Regulatory Identification A breathing circuit bacterial filter is a device that is intended to remove microbiological and particulate matter from the gases in the breathing circuit. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 A substantially equivalent determination assumes compliance to 895. with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) ---------inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. {1}------------------------------------------------ Page 2 - Mr. Scott Ryan This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4648. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
