Spectra S1 Plus and Spectra S2 Plus (K150476) manufactured by Uzinmedicare Co. The predicate device has not been subject to any design related recalls.

# 5. Device Description

The MINUET LCD and MINUET LCD eco are portable, multiple-user, powered breast pumps to be used in home or health care settings. These devices are the same, except the MINUET LCD has a rechargeable battery whereas the MINUET LCD eco does not. The devices have two major components: control unit (pump) and breast shield kit (breast shield, diaphragm, tubing, silicone massager, and bottle components). Users have the option of single or double pumping. The devices have two operating modes: massage and expression. The massage mode has seven suction levels whereas the expression mode offers nine suction levels. The vacuum strength range is 50-280 mmHq.

# 6. Indications for Use

The MINUET LCD and MINUET LCD eco are multiple-user, powered breast pumps intended to express and collect milk from the breasts of lactating women.

# 7. Comparison of Intended Use and Technological Characteristics of the Subject Device and Predicate Device

| Devices | K180075 (subject devices) | K150476 (predicate device) |
|------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Indications for Use | The MINUET LCD and MINUET LCD<br>eco are multiple-user, powered breast<br>pumps intended to express and<br>collect milk from the breasts of<br>lactating women. | The Spectra S1 Plus and Spectra S2 Plus<br>are single-user, powered breast pumps<br>intended to express and collect milk from<br>the breasts of lactating women. |
| Pump type | Same as the predicate | Diaphragm |
| Vacuum strength | Same as the predicate | 50-280 mmHg |
| Suction level | Massage Mode: 7 levels | Massage Mode: 5 levels |
| Suction level | Expression Mode: 9 Levels | Expression Mode: 12 Levels |
| Cycle speed | Massage Mode: 23-120 cycles/min<br>Expression Mode: 13-60 cycles/min | 38-70 cycles/min |
| Back flow protection | Same as the predicate | Backflow protector (diaphragm) on the top<br>of milk collection assembly |
| Visual indicator | Same as the predicate | LCD |
| Software control | Same as the predicate | Yes |
| Power supply - Mains | AC/DC adapter with micro USB cable | AC/DC converter |
| Power supply - Battery | Same as the predicate | Rechargeable lithium ion battery |
| Pump option | Same as the predicate | Single or double |

The subject and predicate devices have intended use – expressing mill from the breasts of lactating women. They also use the same fundamental technoloqy - a microprocessor-controlled diaphragm pump and a solenoid. They have the same vacuum strength range, backflow prevention mechanism, and pump options. They also have comparable power supplies.

The subject and predicate devices have different technological characteristics, as they have different suction levels under each operational mode. Also, the subject devices have high cycle speed up to 120 cycles/min under massage mode. These differences between the subject and predicate devices do not raise different questions of safety and effectiveness.

# 8. Summary of Non-Clinical Performance Testing

The following studies have been conducted on the subject devices to support substantial equivalence to the predicate device:

- Biocompatibility studies on the breast shield, as follows: .
- Cytotoxicity testing per 10993-5:2009 O
- Guinea Pig Maximization Sensitization testing per ISO 10993-10:2010 O
- Irritation testing per ISO 10993-10:2010 O
- Electrical safety testing in accordance with: .
- IEC 60601-1:2005+ CORR. 1 (2006) + CORR. 2 (2007) + AM1 (2012) O
- IEC 60601-1-11:2015 O

{5}------------------------------------------------

- Electromagnetic compatibility testing per IEC 60601-1-2:2014 .
- Battery safety testing in accordance with: .
- AAMI/ANSI ES60601-1:2005 o
- IEC 62133:2012 o
- . Software verification and validation testing in accordance with FDA quidance: "The content of premarket submissions for software contained in medical devices" dated May 11, 2005
- . Bench tests using internal test protocols to demonstrate device performance, including vacuum level settings, speed settings, backflow/cross-contamination protection, battery operation, and use-life

#### 9. Conclusion

The subject and predicate devices have the same intended use. Although there are differences in technological characteristics between the subject and predicate devices, these differences do not raise different questions of safety or effectiveness. The performance data demonstrate that the subject devices are substantially equivalent to the predicate device.
