Intended Use

The MEDOS HILITE 1000 & 800 LT Hollow Fiber Oxygenators are indicated for use in procedures requiring the extracorporeal oxygenation of and carbon dioxide removal from human blood. The 1000 & 800 LT are neonate, infant oxygenators intended for use at blood flow rates of 0.2 to 1.0 liters per minute for the HILITE 1000 and 0.2 to 0.8 liters per minute for the HILITE 800 LT for periods of up to six (6.0) hours. Federal Law (US) restricts this device to sale by or on the order of a physician.

Device Story

Hollow fiber membrane oxygenator with integrated heat exchanger; used in cardiopulmonary bypass for neonates/infants. HILITE 1000 utilizes polypropylene gas-permeable mat; HILITE 800 LT utilizes polymethylpentene plasma-tight mat. Heat exchanger uses polyester non-porous hollow fibers within polycarbonate housing. Blood flows outside fibers; water flows through inner lumen for heat exchange. Device facilitates gas exchange and temperature control during extracorporeal circulation. Operated by perfusionists/physicians in clinical settings. Benefits include efficient gas exchange and thermal regulation during short-term bypass procedures.

Clinical Evidence

Bench testing only. No clinical data provided. Safety and performance validated through functional testing in accordance with FDA Guidance for Cardiopulmonary Bypass Oxygenators.

Technological Characteristics

Hollow fiber membrane oxygenator and heat exchanger. Materials: polypropylene (HILITE 1000), polymethylpentene (HILITE 800 LT), polyester (heat exchanger fibers), polycarbonate (housing). Principle: gas exchange via hollow fiber membrane; heat exchange via non-porous hollow fibers. Standalone device. No software/electronics.

Indications for Use

Indicated for neonates and infants requiring extracorporeal oxygenation and CO2 removal during cardiopulmonary bypass. Flow rates: 0.2-1.0 L/min (HILITE 1000) and 0.2-0.8 L/min (HILITE 800 LT). Duration: up to 6 hours. No contraindications noted.

Regulatory Classification

Identification

A cardiopulmonary bypass oxygenator is a device used to exchange gases between blood and a gaseous environment to satisfy the gas exchange needs of a patient during open-heart surgery.

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Guidance for Cardiopulmonary Bypass Oxygenators 510(k) Submissions.”

#### Classifications Names & Citations: 4.

21 CFR 870.4350, Oxygenator, Cardiopulmonary Bypass, Class II, DTZ, Cardiovascular

### 5. Description:

The MEDOS HILITE 1000 & 800 LT Hollow Fiber Oxygenators consist of a hollow fiber membrane oxygenator and extracorporeal heat exchanger. The MEDOS HILITE 1000 hollow fiber membrane consists of a polypropylene gas permeable mat. The MEDOS HILITE 800 LT hollow fiber membrane consists of a polymethylpentene plasma tight mat. The unique mat design increases the interaction between blood and gas, creating a highly efficient blood oxygenator. The heat exchanger consists of a polyester non-porous hollow fiber configured heat exchanger as the primary element to effect heat exchange. This element is encased by a polycarbonate housing, which directs the blood around the outside of the fibers while water flows through the inner lumen of the fibers and therefore effects heat exchange while minimizing priming volume.

#### Indications for use: 6.

The MEDOS HILITE 1000 & 800 LT Hollow Fiber Oxygenators are indicated for use in procedures requiring the extracorporeal oxygenation of and carbon dioxide removal from human blood. The 1000 & 800 LT are neonate, infant oxygenators intended for use at blood flow rates of 0.2 to 1.0 liters per minute for the HILITE 1000 and 0.2 to 0.8 liters per minute for the HILITE 800 LT for periods of up to six (6.0) hours.

#### 7. Contra-indications:

For oxygenators, no contra-indications have been noted.

#### 8. Comparison:

The MEDOS HILITE 1000 & 800 LT Oxygenators have the same device characteristics as the predicate device.

#### 9. Test Data:

In accordance with FDA Guidance for Cardiopulmonary Bypass Oxygenators 510(k) submissions, the MEDOS HILITE 1000 and 800 LT Oxygenators have completed extensive safety, performance, and validation testing prior to release. Final testing for the systems includes various performance tests designed to ensure that the device meets all of its functional requirements and performance specifications. Safety tests have further been performed to ensure the device complies with applicable industry and safety standards.

### 10. Literature Review:

A review of literature pertaining to the safety and effectiveness has been conducted. Appropriate safeguards have been incorporated in the design of the MEDOS HILITE 1000 & 800 LT Oxygenator.

### 11. Conclusions:

Based upon the testing and comparison to the predicate device, the MEDOS HILITE 1000 & 800 LT Oxygenators have the same intended use, with similar technological characteristics. MEDOS Medizintechnik AG therefore posits that its device is equivalent in safety and effectiveness to predicate devices.
