Abstract
Heart failure with preserved ejection fraction (HFpEF) is a serious condition in which the stiffened left ventricle cannot properly contract or relax, compromising oxygenated blood flow to the rest of the body. This puts excess strain on the left atrium and can eventually lead to cardiogenic shock. The current solution for HFpEF is the implantation of a left ventricular assist device (LVAD), a device containing a pump that is implanted in your chest to effectively bypass the left ventricle. Modern designs however require an external power supply and controller which restrict user mobility and lifestyle. A transdermal inductive rechargeable battery has been designed in collaboration with faculty from SBHSE and medical students from Creighton University to enable the elimination of the percutaneous lead that acts as an active wound site, as well as the elimination of wearable battery packs. The battery design is novel as implantable rechargeable batteries on the market are only capable of powering low-requirement devices such as pacemakers. An LVAD requires approximately 5V on average, leading the BEATBattery design to include a 12V battery implementing step-down mechanisms to allow for a large stored charge to reduce interval time between charging. The BEATBattery is designed to be implanted in the abdomen to reduce potential for undesirable interactions in placement and charging process. Implantation is made possible through the BEATBattery’s design in which the battery is housed in insulating rubber silicone and all device components are coated in biocompatible epoxy. In order to charge the BEATBattery, an inductive module must be placed at the surface at the skin twice a day with a charge time of less than an hour. The BEATBattery poses high potential in the biomedical industry and has potential applications to additional high-power implanted medical devices on the market.
