The summary describes a standard endotracheal tube with a pressure indicator, and the performance studies focus on physical, mechanical, and biocompatibility testing. There is no mention of AI, ML, image processing, or data-driven performance metrics.
Yes
The device, an Endotracheal Tube, is used for airway management and aiding in the removal of subglottic secretions, which are therapeutic interventions.
No
The device is an endotracheal tube intended for airway management and removal of subglottic secretions, describing functions related to treatment and support rather than diagnosis. While one variant has a pressure indicator to "monitor intra-cuff pressure," this monitoring serves to ensure proper device function and patient safety during treatment, not to diagnose a medical condition.
No
The device description clearly describes a physical Endotracheal Tube, a hardware medical device, and details physical, mechanical, and chemical testing.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "airway management by oral intubation and aid in the removal of subglottic secretions." This is a direct medical intervention on a patient's body, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The device is an "Endotracheal Tube," which is a physical device inserted into the airway. It's used for mechanical support and secretion removal, not for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any diagnostic testing procedures.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.

Dear Diana Hong:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal
