What is the difference between the performance, clinical performance and clinical benefit?

In accordance with the MDR, the performance of a device is its ability to achieve its intended purpose as stated by the manufacturer, and may relate to the user of the device.

By extension, the clinical performance of a device is the ability of the device to achieve its intended purpose, thereby leading to a clinical benefit when used as intended.

Clinical benefit means the positive impact of a device on the health of
an individual, expressed in terms of a meaningful, measurable, patient-relevant clinical outcome(s), including outcome(s) related to diagnosis, or a positive impact on patient management, or public health.
