Publication number: 20190117863Abstract: A positive displacement pump that triggers with the beating of a mammalian heart, through the monitoring of an ECG signal is disclosed. A programmable delay from the detection of the forthcoming contraction of the heart enables the pump to syncopate the ejection of the fluid with the events occurring in the cardiovascular system. This delayed ejection could be used to overlay the ejected fluid from the pump with a pressure wave in the artery of systemic circulation through a catheter connection between the pump and a physiological model (e.g., cow, dog, human). The outcome of this use could be to raise the pulse pressure in the system to take advantage of physiological pathways that respond to this transient change in blood pressure. The novelty of this system stems from the adaptable control architecture designed to augment the pulsatile characteristics of the cardiovascular system.Type: ApplicationFiled: October 4, 2018Publication date: April 25, 2019Inventor: Charles Taylor
