Intended Use
The LUNG FLUTE™ is indicated for the collection of sputum samples for laboratory analysis and pathologic examination.
Device Description
The LUNG FLUTE™ is shaped like a pipe or flute with a plastic mouthpiece at one end. A Mylar reed is attached inside a square hardened plastic tube that flairs on the end to increase the internal air mass, which provides acoustical impedance. When the patient exhales through the "flute-like" device, the reed inside the tube oscillates and acts in tandem with the rest of the device and the lung cavity itself to produce a sound frequency that approximates the resonance frequency of pulmonary secretions. The LUNG FLUTE™ facilitates mucus clearing by generating and delivering a specific low frequency sound that vibrates the airways and lung secretions, causing lung secretions to thin and become expelled.

No
The device description and performance studies focus on the mechanical and acoustic properties of the device for sputum induction, with no mention of AI or ML.

No
The intended use is for sputum sample collection, not for treating a condition, even though its mechanism of action affects secretions.

No

The device is indicated for the collection of sputum samples, which are then used for laboratory analysis and pathologic examination. It is a tool for sample collection, not for diagnosing conditions itself.

No

The device description clearly outlines a physical device with a mouthpiece, plastic tube, and Mylar reed, indicating it is a hardware-based medical device.

Based on the provided information, the LUNG FLUTE™ is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for the collection of sputum samples for laboratory analysis. It is a tool to facilitate the collection process, not a device that performs the diagnostic test itself.
  • Device Description: The description focuses on the mechanical action of the device to help clear mucus and produce sputum. It does not describe any components or processes that analyze biological samples in vitro.
  • Performance Studies: The performance study compares the quality of the collected sputum samples (based on biomarker concentrations) using the LUNG FLUTE™ versus another collection method (nebulized hypertonic saline). It does not evaluate the performance of a diagnostic test performed by the device.
  • Predicate Device: The predicate device is "Sputum induction by nebulized hypertonic saline," which is another method for sample collection, not a diagnostic device.

An IVD device is typically a reagent, instrument, or system intended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. The LUNG FLUTE™'s role is to obtain the sample that will then be used in an IVD test performed elsewhere (in a laboratory).

Summary of Performance Studies

A cohort of chronic bronchitis patients underwent sputum induction using the LUNG FLUTE™ and nebulized hypertonic saline. Sputum samples were analyzed for biomarkers indicative of lower respiratory tract samples. Salivary samples were analyzed representing upper respiratory tract samples. The biomarker analyzed were: Neurophil, Macrophages, Squamous Cells, Interleukin-8, Fibrinogen and Elastase. Wilcoxon signed rank test, using a p
