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.

Special Controls

*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}------------------------------------------------

### Similar - Indications for Use

The indications for use of the proposed device and predicate device are not exactly the same, the main difference is that the proposed device is a level 4 isolation gown, while the predicate device is a level 3 isolation gown. However, the biocompatibility test for proposed device was performed and the results showed no adverse effect. And the performance testing for proposed device was also performed and the results demonstrated that the proposed AAMI4 Isolation Gown can meet the barrier protection level 4 requirement. Therefore, these differences will not affectiveness of the proposed device.

### Similar - Design

The design of the proposed device and predicate device are not exactly the same. The proposed device does not have the Thumb loop and Flexneck™ patented design compared to the predicate device. However, this does not affect the intended use. In addition, the performance testing results demonstrated that the proposed AAMI4 Isolation Gown can meet the barrier protection level 4 required by PB70. Therefore, these differences will not affect the safety and effectiveness of the proposed device.

## Different - Weight per square

The weight per square of the proposed device is different from the predicate device. The weight per of the proposed device is 43 g/m², and the predicate device is 39.97 g/m². However, the difference in the weight per square will not affect the intended use. In addition, the performance testing results demonstrate that the proposed isolation gown can meet the barrier protection level 4 requirement as required by PB70. Therefore, this difference will not affect the safety and effectiveness of the proposed device.

### Different - Size

The size for the proposed device is different from the predicate device. The proposed device is available in one size universal (U), while the predicate device is available in sizes large and X-large. However, the difference in the size will not affect the device performance. This difference will not affect the safety and effectiveness of the proposed device.

#### Different - Hydrostatic pressure

The hydrostatic pressure for the proposed device is different from the predicate device. However, the hydrostatic pressure results demonstrate that the proposed device meets the barrier protection level 4

{8}------------------------------------------------

requirement, i.e., at least 50cmH2O, as required by PB70. Therefore, this difference will not affect the safety and effectiveness of the proposed device.

### Different - Water impact

The water impact for the proposed device is different from the predicate device. However, the water impact test was conducted on the proposed device and the results demonstrate that the proposed device meets the barrier protection level 4 requirement, i.e., no more than 1.0g, as required by PB70. Therefore, this difference will not affect the safety and effectiveness of the proposed device.

#### Different - Breaking strength

The breaking strength for the proposed device is different from the predicate device. Breaking strength is one of the indicators to evaluate the ability of the isolation gown to withstand destructive force. The higher the breaking strength value, the stronger the ability to withstand destructive force. The MD and CD breaking strength of the proposed device are higher than the predicate device. Therefore, this difference will not affect the safety and effectiveness of the proposed device.

## Different - Tearing strength

The tearing strength for the proposed device is different from the predicate device. The CD tearing strength of the proposed device is similar to the predicate device, while the MD tearing strength of the proposed device is smaller than the predicate device. However, the CD and MD tearing strength of the proposed device meets ASTM F2407-20's requirement of greater than 10N. Therefore, this difference will not affect the safety and effectiveness of the proposed device.

#### Different - Linting

The water linting for the proposed device is different from the predicate device. However, the linting test was conducted on the proposed device and the testing results demonstrate that the proposed device can meet the requirements of log10<4. Therefore, this difference will not affect the safety and effectiveness of the proposed device.

#### Different - Seam strength

The seam strength was conducted on the proposed device and the testing results demonstrate that the seam strength of the proposed device meets ASTM F2407-20's requirement of greater than 30N. Therefore, this difference will not affect the safety and effectiveness of the proposed device.

### Different - Barrier protection level

The barrier protection level for the proposed device is different from the predicate device. The barier protection level for the proposed device is level 4, while the barrier protection level for the predicate device is level 3. However, the performance testing results demonstrate that the proposed device can meet the barrier protection level 4 required by PB70. Therefore, this difference will not affect the safety and effectiveness of the proposed device.

{9}------------------------------------------------

Different - Viral barrier (resistance to bacteriophage Phi-X174)

The viral barrier was conducted on the proposed device and the testing results demonstrate that the proposed device can prevent virus penetration, which meets the barrier protection level 4 requirement as required by PB70. Therefore, this difference will not affect the safety and effectiveness of the proposed device.
