The method, device and system for electrical sealing of a puncture opening in a blood vessel wall. In a first embodiment, a vascular sealing probe has two bipolar electrodes formed thereon, is insertable to a position whereat the bipolar tip is adjacent t...
|6371923||Time-domain system and method for relaxation measurement and estimation of indicator dilution for continuous estimation and display of cardiac ejection fraction and end diastolic volume|
The invention estimates a cardiac performance value such as cardiac output (CO) and cardiac ejection fraction (EF) by sensing a downstream indicator concentration signal y(t) that corresponds to an indicator (preferably heat) signal x(t) injected upstream...
|6045512||System and method for continuous estimation and display of cardiac ejection fraction and end diastolic volume|
The cardiac ejection fraction EF is estimated based on the parameters of a model of an indicator (such as thermal) dilution through the heart. A channel model is defined by an upstream indicator injector, such as a heater, positioned preferably in the rig...
