Executive Summary
Hypertension Diagnostics (HDI) has gained what it claims is a significant US patent relating to the core technology in its cardiovascular profiling systems. The patent describes methods and apparatus for processing an arterial blood pressure waveform in order to extract clinically useful information regarding the state of the cardiovascular system. HDI's products can provide blood pressure values and non-invasively detect changes in the compliance or elasticity of large and small arteries. Changes in elasticity can indicate whether a patient has underlying vascular disease that might require further evaluation, says the St Paul, Minnesota firm.
