Indications for Use
The Sleepnet Mojo 2 Full Face Vented Mask, Veraseal 3 Full Face Vented Mask, and V3 Full Face Vented Mask are intended to be used with positive airway pressure devices, such as CPAP or bi-level, operating at or above 3 cm H2O. The masks are to be used on adult patients (>30 kg.) for whom positive airway pressure therapy has been prescribed.
Device Story
Patient interface masks (Mojo 2, Veraseal 3, V3) for delivery of positive airway pressure therapy; used with CPAP or bi-level devices. Masks provide seal over nose and mouth; include exhalation port for CO2 flushing and anti-asphyxia valve for fault conditions (e.g., power failure). Used in home or hospital/institutional settings by adult patients. Devices are passive until connected to a blower. Magnets in mask/headgear clips facilitate attachment. Updated labeling includes contraindications and warnings regarding magnetic field interference with medical implants (e.g., pacemakers, ICDs) to prevent potential displacement or malfunction of implants. No physical device modifications made.
Clinical Evidence
No clinical data; bench testing only. Performance data from the predicate device was leveraged as the subject device design is identical.
Technological Characteristics
Full face vented masks with gel bladder, mask shell (soft or rigid), exhalation elbow with anti-asphyxia valve, and 4-point headgear. Materials identical to predicate. Permanent magnets (380mT field strength) used in headgear clips. Non-sterile. Cleaning via mild soap/water or isopropyl alcohol. ISO 10993-1 compliant for permanent surface/tissue contact.
Indications for Use
Indicated for adult patients (>30 kg) prescribed non-invasive positive airway pressure therapy (CPAP or bi-level) at or above 3 cm H2O. Contraindicated for patients or individuals in close physical contact with the mask who have active medical or metallic implants (e.g., pacemakers, ICDs, neurostimulators, aneurysm clips, metallic stents, ocular implants, insulin pumps, CSF shunts, cochlear implants, dental implants, metallic cranial plates) that may interact with magnets.
Regulatory Classification
Identification

#### Discussion of Differences
The subject device includes a new contradiction and updated warning, which was not included in the predicate device – K190254. There are no other differences between the subject and predicate devices.
In March 2024, Sleepnet underwent a voluntary recall (Event 94169) of its masks that contained magnets. Specifically, the subject device was part of this recall. This recall was initiated based on information obtained from post market surveillance indicating a possible risk to patients and anyone in close physical contact with the subject device, having an active medical implant or metallic implant that can be impacted by the magnetic field.
The magnets in these masks provide a quick and easy method of attaching and detaching the mask from the headgear. However, when a magnet comes into close proximity to certain medical implants or metallic implants, it could interfere with the performance or the position of the implant. This could potentially lead to serious injury or death.
Therefore. Sleepnet intends to update its contraindications and warnings as a proactive measure to provide additional safety information to patients and healthcare professionals. To date, there has been no Medical Device Reports associated with the Sleepnet masks with magnets.
Modifications Made to device: No modifications have been made to the device.
Modifications to Labeling:
The Instructions for Use (IFU) have been updated with the following new contraindication and revised warning statement.
#### New Contraindication
Do not use this mask if you or anyone (example: household members, bed partners, caregivers, etc.) in close physical contact with your mask has an active medical implant or metallic implant that will interact with magnets. Implant examples include, but are not limited to, pacemakers, implantable cardioverter defibrillators (ICD), neurostimulators, aneurysm clips, metallic stents, ocular implants, insulin/infusion pumps, cerebral spinal fluid (CSF) shunts, embolic coils, metallic splinter, implants to restore hearing or balance with implanted magnets (such as cochlear implants), flow disruption devices, contact lenses with metal, dental implants, metallic cranial plates, screws, burr hole covers, bone substitute device, magnetic metallic implants/electrodes/valves placed in upper limbs, torso, or higher, etc. If you have any questions regarding the implant, consult your physician or the manufacturer of your implant.
{14}------------------------------------------------
### Updated Warning
Magnets are used in the mask and headgear clips with a field strength of 380mT. With the exception of the devices identified in the contraindication, ensure that the mask is kept at least 6 inches (approx.16 cm) away from any other medical implants or medical devices that can be impacted by the magnetic fields to avoid possible effects from localized magnetic fields. For instance, the functioning of implants may change, or implants may move within the body due to magnetic attraction/repulsion. This applies to you or anyone in close physical contact with your mask.
#### Discussion of Differences
Apart from the contraindication and updated warning above, there are no other differences between the subject devices and the predicate K190254 devices.
### Substantial Equivalence Conclusion
The Sleepnet Mojo 2 Full Face Vented Mask, Veraseal 3 Full Face Vented Mask, and V3 Full Face Vented Mask have identical indications, technological characteristics and principles of operation and performance to the predicate and performance testing demonstrates that the subject device is substantially equivalent to the predicate.
