Intended Use
Sheridan cuffed, uncuffed and reinforced tracheal tubes are designed for oral or nasal intubation and are indicated for airway management.
Device Story
Sheridan Spiral-Flex Endotracheal Tubes are sterile, single-use devices designed to establish a patent airway for ventilation. The tube is inserted into the trachea via the mouth or nose. It features a spiral wire embedded between two layers of PVC, a compatible cuff, inflation line, pilot balloon, one-way valve, and a 15mm connector. The device is used by clinicians in clinical settings for airway management. The tube facilitates mechanical ventilation or oxygenation, benefiting patients requiring airway support. The device includes a Murphy eye, bite block, and X-ray marker for clinical positioning and safety.

## Dear Lori Pfohl:
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 statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part
{1}------------------------------------------------
801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4. Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

## J. Comparison to the Predicate
Table 7.1 illustrates the similarities and differences between the subject and predicate devices. The basic technological and operating principles are the same for both devices. Although the wording is not identical, both the subject and predicate devices are for airway management. Both the subject and predicate devices are intended for similar patient populations adult and pediatric, male and female. Both the subject and predicate devices are disposable, sterile, single patient use devices. As evidenced by comparison Table 7.1. above, the subject device is substantially equivalent to the predicate device. There are no significant differences that would affect safety and efficacy.
## K. Performance Data
The bench testing performed verifies that the performance of the subject device is substantially equivalent in terms of critical performance characteristics to the predicate device. These tests include:
- Visual Inspection (No delamination on tip of reinforced tubes) ●
- Cuff inflation deflation test ●
- Inflation system leak test
- Cuff herniation test
- Pilot Cuff Pull test ●
- Simulated Use Test
- ISO 10993-1:2009 - Biological Evaluation of Medical Devices -- Part 1: Evaluation and testing within a risk management process
The testing performed verifies that the performance of the subject device is substantially equivalent in terms of critical performance characteristics to the predicate device.
The subject devices were tested to the requirements of ASTM F623.
{6}------------------------------------------------
# L. Conclusion
The subject device has the same intended use and technological characteristics and construction as the predicate. Test results demonstrate that the subject device meets it's intended use. It is for these reasons that the subject device can be found substantially equivalent to the predicate devices.
