Intended Use
The KING LTS is intended for use in adult patients (in excess of 25 kg) for controlled ventilation during anesthesia for procedures that are short in duration oonlour vehilation is considered to have a low risk of aspiration of stomach contents.
Device Description
Tube with two attached, inflatable balloons. Ventilation openings between the balloons. Can be sterilized in an autoclave. Proximal ISO Standard 15mm connector for attachment to breathing circuit. Medical grade polymers or approved materials for all components in contact with the anesthesia gas stream. Connected to a Breathing Circuit. Inserted blindly. Seals the esophagus. Cuffs are inflated with one inflation port. Instructions that patient should have fasted before using the product. Latex free product.
More Information

No
The summary describes a mechanical airway device with no mention of software, algorithms, or any features indicative of AI/ML.

Yes
The device is described as affecting the body directly by facilitating controlled ventilation during anesthesia, which aligns with the definition of a therapeutic device.

No
The device description indicates it is used for controlled ventilation during anesthesia, and its components describe an airway device. There is no mention of it being used to identify or analyze a medical condition.

No

The device description clearly outlines a physical tube with inflatable balloons, connectors, and materials, indicating it is a hardware device, not software-only.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a device used for controlled ventilation during anesthesia. This is a direct intervention on a patient's respiratory system, not a test performed on a sample taken from the body to diagnose a condition.
  • Device Description: The description details a physical airway device with balloons and connectors for a breathing circuit. This aligns with a medical device used for airway management, not a diagnostic test kit or instrument.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information about a patient's health status.

In summary, the KING LTS is a medical device used for airway management, not an in vitro diagnostic device.
