Description:

The Marquette Tonoport V is an ambulatory blood pressure monitor. The accuracy of its blood pressure measurement technology has yet to be proven to MDR requirements. Blood pressure measurements are taken from the upper arm. It is intended for ambulatory blood pressure monitoring.

Assessment:

There appears to be no peer-reviewed clinical validation information available on the technology used in the Marquette Tonoport V to measure blood pressure. However, this device appears to be very similar to a validated device by the same (OEM) manufacturer, but equivalence needs to be proven according to a protocol compliant with (EU) 2017/745 and MEDDEV 2.7/1 rev 4.

Recommendations:

	Accuracy Assessment	Recommendation	Basis
BP	Medaval	None	Although equivalence to another device is claimed, this has not been tested to MDR requirements.

Validation Publications for Equivalent Devices:

Note: This is a provisional list, as equivalence according to EU Regulation 2017/745 (e.g. MEDDEV 2.7/1 rev 4) is not proven. Accordingly, these publications are not used in the assessment of star-ratings.
