Intended Use

The AeroChamber Plus* Flow-Vu* Anti-Static Valved Holding Chamber is intended to be used by adult and pediatric patients who are under the care or treatment of a physician or licensed healthcare professional. The device is intended to be used by these patients to administer aerosolized medication from most pressurized Metered Dose Inhalers and Soft Mist Inhalers. The intended environments for use include the home, hospitals and clinics. It is a single patient, multiple use device.

Device Story

AeroChamber Plus Flow-Vu is a valved holding chamber (VHC) designed to interface between a pMDI or SMI and a patient. It contains an aerosol plume from the inhaler, allowing for a delay between device actuation and patient inhalation. A valve acts as a movable barrier, directing patient exhalation away from the chamber to minimize aerosol loss. Used in home, hospital, or clinic settings by patients under professional care. The device helps ensure consistent delivery of aerosolized medication, potentially improving drug deposition. It is a single-patient, multi-use device.

Clinical Evidence

No clinical data. Substantial equivalence is supported by bench-only aerosol characterization testing comparing SMI formulations with and without the VHC, and mechanical/biocompatibility testing for the new mask configuration.

Technological Characteristics

Constructed of thermoplastic polymer, thermoplastic elastomer, and silicone. Dimensions: 5.86" length x 1.75" diameter; 149 cc volume. Operates as a valved holding chamber. Non-sterile, single-patient, multi-use. Biocompatibility testing conducted per ISO 10993 standards (parts 3, 5, 10, 11, 12, 17, 18).

Indications for Use

Indicated for adult and pediatric patients under the care of a physician or licensed healthcare professional for the administration of aerosolized medication from pressurized Metered Dose Inhalers (pMDI) and Soft Mist Inhalers (SMI).

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.

Predicate Device AeroChamber Plus* Flow-Vu* Anti-Static Valved Holding Chamber Trade Name: 510(k) Number: K112010 510(k) Owner: Trudell Medical International The predicate device has not been subject to a recall. ## 4. Device Description The AeroChamber Plus* Flow-Vu* Anti-Static Valved Holding Chamber (VHC) is a holding chamber used for the administration of aerosolized medications. The AeroChamber Plus* Flow-Vu* Anti-Static VHC line of products is designed to be used with a broad range of FDA approved pressurized metered dose inhaler (pMDI) or soft mist inhaler (SMI) pharmaceutical formulations prescribed by a healthcare provider. It is a single patient, multi-use device intended to be used by patients who are under the care or treatment of a licensed health care professional. This device is not used with a specific drug nor is it distributed with such drugs. # 5. Principle of Operation The VHC has two primary modes of operation, one is to contain an aerosol plume from a metered dose inhaler or soft mist inhaler and the second is to deliver the aerosol to the patient. The device is designed to allow for the potential delay between actuation of the metered dose inhaler and the inhalation breaths of the patient. The containment is accomplished by a valve acting as a movable barrier between the chamber and the mouthpiece or mask. The valve acts to direct the patient's exhalation away from the chamber to minimize any aerosol loss to the atmosphere between inhalation breaths. The chamber is sized to ensure the proper amount of aerosol is available for delivery through the valve. {4}------------------------------------------------ # Section 5 - 510(k) Summary ## 6.

All in vitro and in vivo studies were performed by an independent source and included the following battery of tests: Cytotoxicity, Sensitization, Intracutaneous Reactivity, Acute Systemic Toxicity, Genotoxicity and Extractables/Leachables with a Biological Risk Assessment. {9}------------------------------------------------ # Section 5 - 510(k) Summary | ISO Standard | Biological Endpoint | |--------------|---------------------------------------------------------------------------------------| | 10993-5 | Tests for In Vitro Cytotoxicity | | 10993-10 | Tests for Irritation and Skin Sensitization | | 10993-11 | Tests for systemic toxicity (Acute Toxicity) | | 10993-3 | Tests for genotoxicity (Bacterial Reverse Mutation Study and Mouse Lymphoma Assay) | | 10993-12 | Sample preparation and reference materials | | 10993-17 | Establishment of allowable limits for leachable substances | | 10993-18 | Chemical characterization of materials | ## Summary of Biocompatibility Testing Conducted # 9.3 Mechanical Testing (AeroChamber Plus* Flow-Vu* Anti-Static VHC, Adult Small Mask) The following mechanical tests were performed on the subject device: - . Environmental Testing - Flow Performance ● - Life Cycle Testing . - . Drop Testing - Resistivity Verification # 10. Clinical Performance Summary Not applicable, the determination of substantial equivalence is not based on Clinical Performance data. # 11. Conclusion Change in Intended Use for AeroChamber Plus* Flow-Vu* Anti-Static VHC product line: The non-clinical data demonstrate that the AeroChamber Plus* Flow-Vu* Anti-Static VHC (facemask and mouthpiece configurations) used in combination with Soft Mist Inhaler formulations is comparable to use of a SMI formulation alone. Use of the VHC device with an SMI does not raise any new questions of safety and/or effectiveness. Addition of AeroChamber Plus* Flow-Vu* Anti-Static VHC Adult Small Mask configuration: The non-clinical data demonstrate that the AeroChamber Plus* Flow-Vu* Anti-Static VHC, Adult Small Mask is substantially equivalent to the predicate (AeroChamber Plus* Flow-Vu* Anti-Static VHC, Adult Large Mask). Use of the subject device does not raise any new questions of safety and/or effectiveness.
