By imitating the human heart\u2019s primary pumping principle, a physiological pressure and flow is created that should reduce the risk of blood clots and provide energy-efficient pumping. These factors are important to give the patient a good quality of life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Over the years, Realheart has developed a series of prototypes and gradually solved one challenge after another. Blood circulation, pump function, pressure, and pulse generation have been verified in ethically approved animal experiments.<\/p>\n\n\n\n<div style=\"height:41px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Development plan<\/h2>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"851\" src=\"https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera-1024x851.jpg\" alt=\"\" class=\"wp-image-4682\" srcset=\"https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera-1024x851.jpg 1024w, https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera-300x249.jpg 300w, https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera-768x638.jpg 768w, https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera-526x437.jpg 526w, https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera-720x598.jpg 720w, https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera-960x797.jpg 960w, https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera-1140x947.jpg 1140w, https:\/\/dev.realheart.se\/wp-content\/uploads\/2021\/09\/blobar-eng-kopiera.jpg 1447w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Preclinical studies<\/h4>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h5 class=\"wp-block-heading\" style=\"font-size:18px\"><strong>Digital studies<\/strong><\/h5>\n\n\n\n<ul class=\"wp-block-list\"><li>Virtual implants in animals and human heart failure patients in collaboration with Virtonomy GmbH<\/li><li>Computer simulation of blood flow in the pump (Computational Fluid Dynamics, CFD) in collaboration with University of Bath under the direction of Dr. Katharine Fraser&nbsp;<\/li><\/ul>\n\n\n\n<h5 class=\"wp-block-heading\" style=\"font-size:18px\"><strong>Laboratory studies<\/strong><\/h5>\n\n\n\n<ul class=\"wp-block-list\"><li>Blood tests at Karolinska University Hospital in a jointly run laboratory&nbsp;<\/li><li>Performance studies in simulated clinical scenarios using a hybrid mock circulation simulator (simulating the human body) at KU Leuven under the direction of Dr. Libera Fresiello<\/li><li>Blood flow pattern analysis using 4D MRI in collaboration with Link\u00f6ping University<\/li><li>Endurance tests of components and the whole TAH system in custom made test rigs at Realheart&#8217;s laboratory in V\u00e4ster\u00e5s<\/li><\/ul>\n\n\n\n<h5 class=\"wp-block-heading\" style=\"font-size:18px\"><strong>Anatomical and animal studies<\/strong><\/h5>\n\n\n\n<ul class=\"wp-block-list\"><li>Anatomy studies in humans under the direction of Professor Bart Meyns at KU Leuven<\/li><li>Short-term and long-term studies in sheep at Medanex Clinic in Belgium&nbsp;<\/li><\/ul>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Clinical trials<\/h4>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">As artificial hearts are not a common product category the description below is the current best estimate of the route to market.
