Intended Use
The Aradigm Corporation SmartMist™ Asthma Management System is intended for use by asthma patients who self medicate with metered dose inhalers (MDI) and who measure peak expiratory flow rate (PEFR) as part of their asthma management programs.
Device Description
The Aradigm Corporation SmartMist™ Asthma Management System is a single patient use prescribed metered dose inhaler (MDI) accessory and peak flow meter. The SmartMist™ is composed of the non-disposable, battery powered, portable SmartMist™ Controller and the SmartMist™ Spirometry Airway. In addition to it; primary purpose of assisting with drug delivery and its secondary purpose of monitoring lung function of patient compliance monitoring is available. The SmartMist™ Asthma Management System is designed to work with a particular style of MDI, without modification. The entire MDI-canister and plastic actuator-is inserted into the SmartMist™ without the introduction of any flaps or valves. The MDI is easily removed for cleaning or for manual dosing should the SmartMist™ become inoperable. As the patient inhales through their prescribed MDI that they have inserted into the SmartMist™, the device's microprocessor monitors the inhalation flow rate and volume detected by the system's pressure transducer. If the inhalation flow rate and volume fall within the factory programmed parameters, the microprocessor triggers its mechanism to actuate the MDI canister; aerosol medication is delivered to the patient. Feedback regarding the inhalation flow rate is provided to the patient in the form of red and green LEDs. When the green LED is illuminated, the patient is breathing at the recommended inhalation rate for aerosol drug delivery. The SmartMist™ Asthma Management System also functions as an electronic peak flow meter. When the user exhales through the Spirometry Airway, the device's microprocessor determines the peak expiratory flow rate (PEFR) and forced expiratory volume in one second (FEV). The peak flow rate is displayed to the patient in the liquid crystal display window. A record of PEFR, FEV , and dosing (inhalation) events is stored in the SmartMist™ memory for later retrieval, if desired, by a trained medical practitioner. Therefore, the SmartMist™ also provides patient compliance monitoring at the option of the practitioner. Use of MDI medications with the SmartMist™ provides to the patient continual inhalation technique training. Since the SmartMist™ will not deliver the medication unless the patient's inhalation is at the proper flow rate, the patient eceives technique feedback each time the SmartMist™ is used for delivery of medication. Red and green indicators provide easily understood flow rate feedback to the patient.

The device description explicitly states it is composed of hardware components: a non-disposable, battery powered, portable SmartMist™ Controller and the SmartMist™ Spirometry Airway. It also mentions a microprocessor, pressure transducer, LEDs, and a liquid crystal display window.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The SmartMist™ Asthma Management System is a device that assists with drug delivery (metered dose inhaler accessory) and monitors lung function (peak flow meter). It interacts directly with the patient's respiratory system (inhaling and exhaling air).
  • No Sample Analysis: The device does not analyze any biological samples taken from the patient. It measures physical parameters related to breathing.

Therefore, the SmartMist™ Asthma Management System falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.

4. Description of Device:

The Aradigm Corporation SmartMist™ Asthma Management System is a single patient use prescribed metered dose inhaler (MDI) accessory and peak flow meter. The SmartMist™ is composed of the non-disposable, battery powered, portable SmartMist™ Controller and the SmartMist™ Spirometry Airway. In addition to it; primary purpose of assisting with drug delivery and its secondary purpose of monitoring lung function of patient compliance monitoring is available.

The SmartMist™ Asthma Management System is designed to work with a particular style of MDI, without modification.

the factory programmed parameters, the microprocessor triggers its mechanism to actuate the MDI canister; aerosol medication is delivered to the patient.

Feedback regarding the inhalation flow rate is provided to the patient in the form of red and green LEDs. When the green LED is illuminated, the patient is breathing at the recommended inhalation rate for aerosol drug delivery.

The SmartMist™ Asthma Management System also functions as an electronic peak flow meter. When the user exhales through the Spirometry Airway, the device's microprocessor determines the peak expiratory flow rate (PEFR) and forced expiratory volume in one second (FEV). The peak flow rate is displayed to the patient in the liquid crystal display window.

A record of PEFR, FEV , and dosing (inhalation) events is stored in the SmartMist™ memory for later retrieval, if desired, by a trained medical practitioner. Therefore, the SmartMist™ also provides patient compliance monitoring at the option of the practitioner.

Use of MDI medications with the SmartMist™ provides to the patient continual inhalation technique training. Since the SmartMist™ will not deliver the medication unless the patient's inhalation is at the proper flow rate, the patient eceives technique feedback each time the SmartMist™ is used for delivery of medication. Red and green indicators provide easily understood flow rate feedback to the patient.

5. Statement of Intended Use:

The Aradigm Corporation SmartMist™ Asthma Management System is intended for use by asthma patients who self medicate with metered dose inhalers (MDI) and who measure peak expiratory flow rate (PEFR) as part of their asthma management programs.

6. Statement of Technological Characteristics:

The SmartMist™ Asthma Management System has no significant change in design, materials, energy source or other technological characteristics compared to the predicate devices. The SmartMist™ Asthma Management System is similar in function to other such devices. The SmartMist™ combines functions that historically have been available to patients only as separate device. The SmartMist™, then, is compared to three separate predicate devices: the MDI medication delivery functions of the SmartMist™ are compare to the Monaghan Medical AeroChamber® MDI Accessory; the spirometry functions are compared to the MEDTRAC Technologies PeakLog™ Peak Flow Meter; and the training functions are compared to the Vitalograph A.I.M. Aerosol Inhalation Monitor.

As an accessory to MDI medication delivery, the SmartMist™ differs from the predicate in that the SmartMist™ is an active electromechanical device rather than a passive mechanical device. For the spirometry functions, the primary difference is the method of pressure measurement. Whereas the predicate device utilizes heated wire technology, the SmartMist™ utilizes solidstate pressure transducer technology. For the training functions, the SmartMist™ trains the patient each time they use the device to inhale their MDI medication. The predicate device only trains in the practitioner's office using a custom placebo MDI.
