No
The device description and performance studies focus solely on the physical properties and filtration capabilities of a surgical face mask. There is no mention of any computational or analytical functions that would involve AI or ML.
No
The device is described as a surgical face mask intended to protect from transfer of microorganisms, body fluids, and particulate matter, which is a barrier function rather than a therapeutic one.
No
Explanation: The device description and intended use clearly state that the Nordiwell Surgical Face Masks are for protection against transfer of microorganisms, body fluids, and particulate matter, serving as a barrier. There is no mention of the device being used to diagnose any condition or disease.
No
The device description clearly outlines physical components (layers of polypropylene, nosepiece, ties/ear-loops) and the performance studies are focused on physical properties and biocompatibility, not software functionality.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the mask is for protecting patients and healthcare workers from the transfer of microorganisms, body fluids, and particulate matter. This is a physical barrier function, not a diagnostic test performed on a sample from the human body.
- Device Description: The description details the physical construction and materials of the mask. There is no mention of reagents, assays, or any components used to analyze biological samples.
- Performance Studies: The performance studies focus on the physical properties of the mask (filtration efficiency, fluid resistance, flammability) and its biocompatibility. These are not studies related to the accuracy or performance of a diagnostic test.
IVD devices are used to examine specimens from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This surgical face mask does not perform any such function.
N/A
Intended Use / Indications for Use
When properly worn, the surgical face masks are intended to patient and healthcare workers from transfer of microorganisms, body fluids and particulate matter. This device is non-sterile and for single use only.

Device Description
The Nordiwell Surgical Face Masks are composed of 3-layers and are flat-pleated. The mask materials consist of an outer layer (polypropylene spunbond, blue), inner layer (polypropylene spunbond white), filter (polypropylene melt-blown, white) and ties (polypropylene spunbond white). The mask contains a malleable nosepiece which is centrally positioned between the opposed side edges along the top edge of the mask. The nosepiece is a stable anchor in the vicinity of the nose and readily bent to conform to contours of a person's face. Thus the nosepiece can provide a firm fit over the nose and then to secure the mask over the users' mouth and face.
The mask is a single use, provided non-sterile.
This device is not made with natural rubber latex and Shelf-life of the device is 2 years.
The subject of this submission is a design change to the ear-loop in the Nordiwell Medical Face Mask(K202615). The ear-loop of the Nordiwell Medical Face Mask(K202615) is changed to tie in the subject device.

§ 878.4040 Surgical apparel.
(a)
Identification. Surgical apparel are devices that are intended to be worn by operating room personnel during surgical procedures to protect both the surgical patient and the operating room personnel from transfer of microorganisms, body fluids, and particulate material. Examples include surgical caps, hoods, masks, gowns, operating room shoes and shoe covers, and isolation masks and gowns. Surgical suits and dresses, commonly known as scrub suits, are excluded.(b)
Classification. (1) Class II (special controls) for surgical gowns and surgical masks. A surgical N95 respirator or N95 filtering facepiece respirator is not exempt if it is intended to prevent specific diseases or infections, or it is labeled or otherwise represented as filtering surgical smoke or plumes, filtering specific amounts of viruses or bacteria, reducing the amount of and/or killing viruses, bacteria, or fungi, or affecting allergenicity, or it contains coating technologies unrelated to filtration (e.g., to reduce and or kill microorganisms). Surgical N95 respirators and N95 filtering facepiece respirators are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9, and the following conditions for exemption:(i) The user contacting components of the device must be demonstrated to be biocompatible.
(ii) Analysis and nonclinical testing must:
(A) Characterize flammability and be demonstrated to be appropriate for the intended environment of use; and
(B) Demonstrate the ability of the device to resist penetration by fluids, such as blood and body fluids, at a velocity consistent with the intended use of the device.
(iii) NIOSH approved under its regulation.
(2) Class I (general controls) for surgical apparel other than surgical gowns and surgical masks. The class I device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9.

7. Description of the change
The sole modification is the replacement of the ear-loop of the predicate device with a tie attachment. The essential function and performance of the face mask depend on the main body of the mask. The function of ear-loop and tie is to allow the main body of the mask to cover important parts of the face to achieve a protective effect. According to the Instruction for Use, both the ear-loop and tie can achieve the function of fixing the mask. So the modification does not affect the indication for use, essential function and performance of the device.
The labeling will require minor changes in the device name, description and donning/doffing procedures.
8. Performance data
8.1. Non-clinical Performance Testing:
(1) Bench testing was conducted to demonstrate the performance of the subject device. The bench testing includes the following tests: Fluid Resistance Performance (ASTM F1862-17) Particulate Filtration Efficiency (ASTM F2299-17) Bacterial Filtration Efficiency (ASTM F2101-19) Differential Pressure (Delta P) (EN 14683:2019, Annex C and ASTM F2100-19) Flammability (16 CFR 1610)
(2) Biocompatibility evaluation and test Biocompatibility evaluation conducted in accordance with the FDA's 2016 guidance and ISO10993-1:2018 supports that the subject devices are biocompatible. The biocompatibility test includes the following tests: In Vitro Cytotoxicity Test(ISO 10993-5: 2009) Skin Irritation Test(ISO 10993-10:2010) Skin Sensitization Test(ISO 10993-10:2010)
8.2. Clinical Performance Testing
No clinical study is included in this submission.
9. Conclusion
7
The conclusion drawn from the nonclinical tests demonstrates that the subject device in 510(K) submission K210181, the Nordiwell Surgical Face Mask is as safe, as effective, and performs as well as or better than the legally marketed predicate device cleared under K202615.
