The Novalung System is indicated for long-term (> 6 hours) respiratory/cardiopulmonary support that provides assisted extracorporeal circulation and physiologic gas exchange (oxygenation and CO2 removal) of the patient's blood in adults with acute respiratory failure or acute cardiopulmonary failure, where other available treatment options have failed, and continued clinical deterioration is expected or the risk of death is imminent. These may include:
- · Failure to wean from cardiopulmonary bypass following cardiac surgery in adult patients
- · ECMO-assisted cardiopulmonary resuscitation in adults
The Novalung System is a blood oxygenation and carbon dioxide removal system designed to provide extracorporeal cardiac and/or pulmonary support. The following therapies are available with the Novalung System:
- Extracorporeal CO2 removal (ECCO2R)
- Extracorporeal membrane oxygenation (ECMO) ●
The Novalung System consists of the Novalung console and XLung kit. The Novalung console is composed of the following components: - Control panel ●
- Power supply ●
- Sensor box ●
- . Pump drive
The Novalung console powers and monitors the operation of the blood pump head in the extracorporeal circuit. The control panel has a touchscreen display on which all data, parameters, and values are displayed. Parameters can be selected and adjusted by pressing the touchscreen as well as by using the control panel function keys and the center knob. The control panel is attached to the power supply, which provides power to the console. The console also provides two (2) battery packs that supply power to the console if there is a power failure.
The sensor box allows data to be transferred to the console and displayed on the control panel. It has connectors for pressure sensors that connect to the XLung kit tubing set and a flow sensor.
The XLung kit contains a disposable tubing set and accessories (gas line, priming line, stopcocks, luer caps, Christmas tree connector, tubing clamps, cable ties). The tubing set is pre-connected to a hollow fiber membrane oxygenator (XLung oxygenator) and blood pump head (Deltastream DP3 3/8"), which forms an extracorporeal circuit. All blood-contacting surfaces of the tubing set, except for the blood pump head, are coated with x.ellence coating.
The XLung kit tubing has 3 integrated pressure sensors (IPS) that connect to the sensor box. The flow sensor detects air bubbles in the extracorporeal circuit and measures blood flow. The XLung kit provides treatment for a blood flow range of 1-7 L/min and has a total extracorporeal priming volume of 605 mL ± 10%.
The blood pump head is pre-connected to the XLung kit tubing set, which is provided sterile. Blood flow in the XLung kit tubing set is driven by the pump drive when it is connected to the blood pump head.
The following accessories are available with the Novalung System: - Bracket and rail connector
- Flow sensor ●
- Pressure sensor connecting cables
- System cart ●
- Compact holder spike and bracket
- Pump drive holders ●
- . Infusion holder
The provided text describes the Novalung System, an extracorporeal circuit and accessories for long-term respiratory/cardiopulmonary failure. It outlines the device's indications for use, its components, and various tests conducted to demonstrate its substantial equivalence to predicate devices. However, the document does not present a table of specific acceptance criteria alongside reported device performance for these tests. Instead, it generally states that "All testing met predetermined acceptance criteria" and provides summaries of the types of tests performed and their overall conclusions.
Therefore, many of the requested details about acceptance criteria, specific performance metrics, sample sizes for test sets, expert qualifications, and ground truth establishment cannot be extracted directly from this document.
Here's a summary of the information that can be extracted or inferred from the provided text, and an explanation for what cannot:

(a)
Identification. An extracorporeal circuit and accessories for long-term respiratory/cardiopulmonary support (>6 hours) is a system of devices and accessories that provides assisted extracorporeal circulation and physiologic gas exchange of the patient's blood in patients with acute respiratory failure or acute cardiopulmonary failure, where other available treatment options have failed, and continued clinical deterioration is expected or the risk of death is imminent. The main devices and accessories of the system include, but are not limited to, the console (hardware), software, and disposables, including, but not limited to, an oxygenator, blood pump, heat exchanger, cannulae, tubing, filters, and other accessories (e.g., monitors, detectors, sensors, connectors).(b)
Classification —Class II (special controls). The special controls for this device are:(1) The technological characteristics of the device must ensure that the geometry and design parameters are consistent with the intended use, and that the devices and accessories in the circuit are compatible;
(2) The devices and accessories in the circuit must be demonstrated to be biocompatible;
(3) Sterility and shelf-life testing must demonstrate the sterility of any patient-contacting devices and accessories in the circuit and the shelf life of these devices and accessories;
(4) Non-clinical performance evaluation of the devices and accessories in the circuit must demonstrate substantial equivalence of the performance characteristics on the bench, mechanical integrity, electromagnetic compatibility (where applicable), software, durability, and reliability;
(5) In vivo evaluation of the devices and accessories in the circuit must demonstrate their performance over the intended duration of use, including a detailed summary of the clinical evaluation pertinent to the use of the devices and accessories to demonstrate their effectiveness if a specific indication (patient population and/or condition) is identified; and
(6) Labeling must include a detailed summary of the non-clinical and in vivo evaluations pertinent to use of the devices and accessories in the circuit and adequate instructions with respect to anticoagulation, circuit setup, performance characteristics with respect to compatibility among different devices and accessories in the circuit, and maintenance during a procedure.
