The heart pumps blood through both pumps at the same time via a downwards movement of the plane between the atria and ventricles \u2013 the atrioventricular plane \u2013 delivering a pulsatile flow. Realheart TAH mimics this movement with its own atrioventricular plane, providing pulsatile blood flow that human organs are adapted to. Realheart TAH is designed to carefully mimic the natural blood flow to minimize blood damage and blood-related side effects that are common with existing heart pumps. To this end, the design undergoes thorough testing using multiple methods, including computer simulations, bench tests, and animal studies.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"rve\" data-content-width=\"474\"><iframe loading=\"lazy\" title=\"Realheart TAH In Depth\" width=\"474\" height=\"267\" src=\"https:\/\/www.youtube.com\/embed\/lLdMcu_P4e8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div><!-- Responsive Video Embeds plugin by www.kevinleary.net -->\n<\/div><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Designed to minimize the risk of infections and internal bleeding<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">During treatment with implanted artificial hearts, infections can occur where the driveline passes through the skin. Realheart uses a thin driveline made of biocompatible material to minimize the risk of infection for the first product, but will evaluate the possibilities of cordless versions for future products.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Blood-related side effects are multifactorial problems. High shear stress and lack of pulse \u2013 both characteristics of existing continuous flow pumps \u2013 are noted as risk factors for many blood-related side effects. High shear stress can also damage blood cells themselves, leading to further complications. Realheart has carried out computer simulation studies in collaboration with University of Bath that concluded that Realheart TAH design results in low shear stress.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">First in the world with atria<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Compared to all other technologies on the market and those under development, we believe that Realheart TAH has the lowest risk of side effects thanks to the device\u2019s natural blood flow pattern. No other technology known to Realheart can achieve pulsatile synchronized pumping on the right and left sides in combination with independently adjusted pumps for right\/left balance, all controlled by the pressures in the atria &#8211; because no other heart pump has atria.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although the product is designed and undergoing tests to minimize the risk of side effects, possible side effects can only be confirmed through clinical trials in patients.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Realheart TAH in Brief \u2022 Delivers physiological blood flow, pressure, and oxygenation&nbsp;\u2022 Uses two atria and two ventricles to closely mimic natural blood flow\u2022 Automatically adjusts blood flow volume based on atrial pressure\u2022 Can pump different blood volume from the right and left ventricle to maintain right\/left balance as in the natural heart.
