In the Arterial line: Arterial blood oxygen partial pressure (pO2), Arterial blood temperature (artT). The duration of application is limited to 6 hours of continuous use. Essenz ILBM consists of the following components / disposables: B-Capta Venous and Arterial Sensors, Essenz ILBM Sensor Module, B-Capta Venous and Arterial Reference Element Holders, B-Capta disposable Venous and Arterial Cuvettes. The B-Capta venous sensor is an optical sensor which measures hematocrit/hemoglobin and oxygen saturation using an optical reflectance technology when connected to its dedicated disposable cuvette.

The Heater-Cooler 3T System is used to circulate water through heat exchangers to warm or cool a patient during cardiopulmonary bypass procedures lasting 6 hours or less.

The Heater-Cooler System 3T is an independent (i.e., independent of the water supply) 3circuit heating/cooling base unit that includes three water circuits for the patient supplied by one tank (for the heating/cooling blanket, the oxygenator) and one interchangeable heating/cooling circuit for cardioplegia. If required, patient and cardioplegia circuits can be switched off separately, in order to increase the activated functional group's heating and/or cooling performance. The following optional components and accessories are also available for the Heater-Cooler System 3T: 1. Heating-cooling blankets; 2. Water circuit tubing; and 3. Various cables. The Heater-Cooler System 3T includes a disposable aerosol collection set that consists of a canister connected to the Heater-Cooler System 3T and the user facility's vacuum source that captures emissions that are drawn from the tank using negative pressure created by the user facility's vacuum. The changes proposed in the current 510(k) include the offering of a Deep Cleaning service by LivaNova to customers. The safety of the Heater-Cooler System 3T is ensured by the regular disinfection and cleaning, monitoring of the bacteria levels and by the aerosol collection set, as described in the Operating Manual that was cleared in K191402. The Deep Cleaning service is intended to address cases where heavily contaminated devices cannot meet the acceptable level described in section 6.5.2 of the Operating Instructions. In this situation, to allow the device to return to clinical use, the customer may choose to return the device for the Deep Cleaning service. The Deep Cleaning service is intended to reduce bioburden levels within the water circuit, thereby reducing the risk of NTM Aerosolization in the clinical setting. There are no changes to design or intended use.

ESSENZ Patient Monitor is a modularly structured program package that is exclusively used with LivaNova Heart-Lung Machines. The system allows detailed recording of perfusion data during cardiopulmonary bypass as well as the processing and evaluation of this data. The data may be recorded automatically or entered manually.

The ESSENZ Patient Monitor is used to collect and view data generated during cardiopulmonary bypass surgery. It interfaces with LivaNova Heart-Lung machines to capture this data. The ESSENZ Patient Monitor includes the following main components: - Software: The data-recording software installed on the Perfusion System Monitor hardware; known as "ESSENZ Patient Monitor". It is used to save and process the collected data. - Hardware: The Perfusion System Monitor. It is used to display and transfer the collected data. - Hardware: A mast holder to mount the Perfusion System Monitor on a vertical mast of the respective LivaNova HLM.
