Noninvasive Central Venous Pressure Monitor

Biological tissue is relatively transparent to near infrared light, and photons can penetrate tissue to a depth of up to a few centimetres.

Mespere’s CVP Monitor shines near infrared photons into the tissue containing central venous blood vessels and analyzes the density variation in the diffusely reflected photons that are associated with the central venous hemodynamics.

Mespere’s handheld monitor connected to a disposable patch, allows physicians to record information such as central venous blood pressure, venous oxygenation and eventually cardiac output are calculated non-invasively in real time, using a pain-free and non-invasive method.

Current Method

The current method of CVP monitoring involves catheterization through a vein into the right atrium of the heart.

First Central Venous Catheterization - 1905
Clinical utilization well established
Over 3 million/year

Limitations of Current Method

Invasive
Expensive
High risk of infection
Application in OR/Catheterization labs only

Benefits of Mespere CVP Monitor

Break though hand-held device with a disposable patch offers physicians and their patients a revolutionary pain-free method for measuring CVP.
Powerful, small and portable
Cost effective with no compromise to patient care
Potential to transform venous monitoring and enable monitoring of venous hemodynamics in cardiologists’ clinics, heart failure clinics, ICU’s, and dialysis clinics.

The technology is based on the patent pending application, United States Utility Patent Application No: 11/707,905, “Method and Device for Measuring Parameters of Cardiac Function”. In addition, Mespere has also filed for patent protection under the PCT for International protection, and specifically has filed PCT International Application No. PCT/CA2008/0026

Our current prototype consists of a Medical tablet PC and sensor patch, we are developing a customized portable device with integrated display and docking station.

Extensible platform design provide for Central Venous Pressure monitoring (CVP) and future development of products for central venous oxygenation (ScvO2), cardiac output, and home monitoring.
