• Device Name: FLUTTER D
• Applicant: Bradstreet Clinical Research Assoc., Inc.
• Product Code: BYI · Anesthesiology
• Decision Date: Jun 5, 1998
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 868.5665
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Flutter®D is to be used to assist in the clearance of excessive secretions from the lungs of patients with cystic fibrosis, bronchitis, bronchiectasis and other diseases which cause the lungs to produce excessive amounts of mucus. It may also be used in conjunction with a medical need for positive expiratory pressure (PEP) therapy.

Device Story

Flutter®D is a handheld, expiration-resisting mucus clearance device. Input: patient exhaled air. Operation: internal high-density steel ball rests in a plastic circular cone; exhaled air forces ball to move, creating resistance and internal airway vibrations. Output: oscillatory vibrations and positive expiratory pressure (PEP). Usage: patient exhales into mouthpiece; vibrations mobilize mucus from deep airways to throat for expectoration. Used in clinical or home settings by patients under medical guidance. Benefits: loosens mucus from airway walls, maintains airway patency during exhalation, and accelerates expiratory airflow to facilitate mucus removal.

Clinical Evidence

No clinical trials performed on the Flutter®D. Equivalence is based on the established clinical efficacy of the predicate Flutter® device in clearing mucus and facilitating expectoration in patients with cystic fibrosis, bronchitis, and bronchiectasis.

Technological Characteristics

Handheld device; materials include hardened plastic mouthpiece, plastic cover, and high-density steel ball. Principle of operation: passive mechanical oscillation via ball-valve resistance. Energy source: patient-generated expiratory airflow. Form factor: handheld. No software or electronic components.

Indications for Use

Indicated for patients with cystic fibrosis, chronic bronchitis, bronchiectasis, or other conditions causing excessive lung mucus production requiring airway clearance and PEP therapy.

Regulatory Classification

Identification

A powered percussor is a device that is intended to transmit vibration through a patient's chest wall to aid in freeing mucus deposits in the lung in order to improve bronchial drainage and that may be powered by electricity or compressed gas.

## SUMMARY OF SAFETY AND EFFECTIVENESS

August 1, 1997 Date of Preparation:

Device Name: Flutter®D Mucus Clearance Device

Powered Percussors Classification Name:

Manufacturer:

Atrion Medical Products Inc. (formerly Ryder International Corp.) for VarioRaw SA, a subsidiary of Scandipharm, Inc., Birmingham, Alabama.

Predicate:

Flutter® Mucus Clearance Device which was cleared for market under K940986 and K946083.

Device Description:

The Flutter®D is a small hand held device consisting of a hardened plastic mouthpiece at one end, a plastic cover with an opening at the other end, and a valve on the inside created by a high density steel ball resting in a plastic circular cone.

Intended Use and Technological Characteristics:

The Flutter®D is to be used to assist in the clearance of excessive secretions from the lungs of patients with cystic fibrosis, bronchitis, bronchiectasis and other diseases which cause the lungs to produce excessive amounts of mucus. It may also be used in conjunction with a medical need for positive expiratory pressure (PEP) therapy.

The Flutter®D is an expiration resisting device that delivers internal vibrations to patients' airways. The moveable ball inside the Flutter®D opposes the patient's exhaled air, creating a resistance to his expiration due to the weight of the steel ball.

The vibrations cause an oscillation effect down in the smallest airway passages within the lungs. With repeated vibrations, mucus secretions are mobilized from deep within the lungs to the throat where they can be huffed up and expectorated.

Clinical and Non-Clinical Similarities and Differences:

The original Flutter® has been shown to be effective in clearing mucus from patients with cystic fibrosis, bronchitis, bronchiectasis and other diseases in which mucus accumulates in the lungs and is effective in dislodging mucus from airway walls and thus facilitating its clearance by subsequent voluntary cough. It may also be useful in conjunction with a medical need for positive expiratory pressure (PEP) therapy.

Although no clinical trials have been performed on the Flutter®D disposable device, the modifications in design and material were minor and did not significantly affect the oscillation patterns generated by a continuous air flow; therefore, Flutter®D will be as effective as the original Flutter® in dislodging mucus from airway walls and facilitating mucus clearance and in conjunction with a medical need for positive expiratory pressure (PEP) therapy.

Dear Ms. Bradstreet:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions aqainst misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic. (QS) . . inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

Device Name: Flutter®D Mucus Clearance Device

Indications for Use:

The efficacy of the Flutter®D as a mucus clearance device for cystic fibrosis patients is based on its ability to 1) vibrate the airways (which loosens mucus from the airway walls), 2) intermittently increase endobronchial pressure (to maintain the patency of airways during exhalation, so that mucus does not become trapped as it moves up the airways), and 3) accelerate expiratory airflow (to facilitate the upward movement of mucus through the airways so that it can be more easily coughed out). Flutter D may also be useful in the removal of mucus from the lungs of patients who have chronic bronchitis or bronchiectasis and in conjunction with a medical need for Positive Expiratory Pressure (PEP) Therapy.
