The summary describes a traditional heart-lung machine with standard components and sensors. There is no mention of AI, ML, or any related technologies in the device description, intended use, or performance studies.
No
The device is a heart-lung machine used during cardiopulmonary bypass. While it assists in maintaining physiological functions during surgery, it is a supportive device, not one directly treating a disease or condition for therapeutic purposes.
No
The device is a heart-lung machine used during cardiopulmonary bypass. It is primarily a therapeutic device that supports the patient's circulatory and respiratory functions, not one that diagnoses medical conditions. While it includes sensors for monitoring, these are for monitoring extracorporeal perfusion during treatment, not for diagnosing a disease.
No
The device description explicitly lists numerous hardware components such as pumps, sensors, clamps, and a console base, indicating it is a physical medical device with integrated software, not a software-only device.
Based on the provided information, the Essenz HLM is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is "to be used during cardiopulmonary bypass for procedures lasting six (6) hours or less." This describes a device used on a patient during a surgical procedure, not a device used to examine specimens from a patient outside the body.
- Device Description: The description details a heart-lung machine with components like pumps, sensors, and controls for monitoring extracorporeal perfusion. These are all components of a system designed to support a patient's circulatory and respiratory functions during surgery.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, tissue, etc.) or providing diagnostic information based on such analysis. The device's function is to mechanically support the patient's vital functions.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. The Essenz HLM does not fit this definition.

VIII. SUBSTANTIAL EQUIVALENCE
The Essenz HLM is as safe and effective as the predicate S5 System. The Essenz HLM has the same intended use and indications, similar technological characteristics, and the same principles of operation as its predicate devices. The minor technological differences between the cleared and modified devices do not raise different questions of safety or effectiveness. Performance and validation data demonstrate that the subject Essenz HLM is as safe and effective as the predicate devices.
