Intended Use

Vortex is indicated for use as a spacer/valved holding chamber for use in delivery of aerosol medication with metered dose inhalers.

Device Story

Vortex is a reusable spacer/holding chamber designed to facilitate aerosolized drug delivery from metered dose inhalers (MDI). The device consists of an anodized aluminum cylinder, an elastomeric MDI adapter, and a valved mouthpiece. The aluminum construction is non-electrostatic to minimize drug deposition. During operation, the MDI is inserted into the adapter; the chamber allows the drug plume to expand before inhalation. Integrated inhalation and exhalation valves reduce the need for precise patient coordination during MDI actuation. The device is intended for use by patients requiring MDI therapy. It is available as a standalone unit or packaged with a mask. The device is cleaned and disinfected by the user. By improving drug delivery efficiency and reducing coordination requirements, the device helps ensure consistent medication administration.

Clinical Evidence

No clinical data. Substantial equivalence was established through bench testing, including drug delivery performance per FDA guidance and inhalation/exhalation resistance measurements (all <250 pascal at 30 lpm).

Technological Characteristics

Reusable valved holding chamber. Materials: Anodized aluminum cylinder (non-electrostatic), elastomeric MDI adapter, and valved mouthpiece. Principle: Expansion chamber with inhalation/exhalation valves to reduce MDI coordination requirements. Dimensions/form factor: Cylindrical chamber. Connectivity: None. Sterilization: Reusable/cleanable.

Indications for Use

Indicated for use as a spacer/valved holding chamber to assist patients in the delivery of aerosolized medication via metered dose inhalers (MDI).

Regulatory Classification

Identification

A nebulizer is a device intended to spray liquids in aerosol form into gases that are delivered directly to the patient for breathing. Heated, ultrasonic, gas, venturi, and refillable nebulizers are included in this generic type of device.

### Device Description

Vortex is a new spacer/holding chamber designed to assist patients using metered dose inhalers (MDI) for aerosolized drug delivery. Vortex may provide enhanced drug delivery, ease of use and ability to clean/disinfect the device.

Vortex is a reusable device consisting of an aluminum cylinder with an elastomeric fitting on one end to accept metered dose inhalers and a valved mouthpiece on the other end to interface with the patient. The elastomeric fitting may be removed for cleaning and/or replacement.

Vortex will be available as a stand-alone item and will also be available packaged with a mask.

#### Intended Use

ve orex is indicated for use as a spacer/valved holding chamber for use in delivery of aerosol medication with metered dose inhalers.

### Technological Characteristics Compared to Predicate Device

Vortex and Aerochamber are both valved holding chambers used to aid in the delivery of MDI v often and released include a cylindrical chamber to allow the MDI drug plume to expand nrior to inhalation by the patient. In addition, both make use of inhalation and exhalation valves to reduce coordination related problems with MDI actuation.

Vortex and Aerochamber make use of thermoplastic components and elastomeric valves and MDI adapters. However, Vortex makes use of a non-electrostatic (anodized aluminum) cylinder to reduce the likelihood of drug deposition on the cylinder.

### Non-clinical Test Summary

Testing to compare Vortex to Aerochamber was conducted. Characteristics evaluated include:

- Drug delivery (per FDA guidance): Respirable drug delivered through Vortex is comparable to . or greater than Aerochamber.
- Fit with MDI elbows: Vortex fit all MDI elbows evaluated. .
