This $195,291 award, effective August 1, 2024 through July 31, 2026, will result in a lumped parameter model that...
- This Project Grant award of $769,994, awarded on September 5, 2025 by the National Heart, Lung, and Blood Institute (CFDA 93.837 - Cardiovascular Diseases Research), supports research to investigate the impact of left ventricular assist device (LVAD) implantation on cerebral hemodynamics and cognition. The project aims to clarify the relationship between LVAD physiology and neurovascular health, with the goal of identifying hemodynamic metrics that can be used to personalize and improve...
- Percassist Inc. received a $663,129 Project Grant award from the National Heart Lung and Blood Institute of the Department of Health and Human Services. The award was made under the Cardiovascular Diseases Research program (CFDA 93.837), which supports heart and vascular research. The grant funds the development of a percutaneous ventricular assist device for chronic heart failure patients. Specifically, Percassist will design and test a balloon catheter implant that can be delivered minimally...
- The National Heart, Lung, and Blood Institute (NHLBI) awarded a $1,024,635 Project Grant under the Cardiovascular Diseases Research program (CFDA 93.837) to Corvion, Inc. in Webster, Texas to develop a Totally Implanted Left Ventricular Assist Device (TI-LVAD). The goal is to create an ultra-low-power blood pump, implantable battery, and wireless charging system that eliminates the need for a percutaneous driveline and external power supply, reducing complications and improving quality of life...
- This Project Grant award of $870,467.00, provided by the National Heart Lung and Blood Institute (CFDA 93.837 - Cardiovascular Diseases Research), supports the development of Ension Inc.'s Bearingless Flux Reversal Motor for Neonatal and Pediatric Extracorporeal Life Support Applications. The project aims to address shortcomings of the current clinically available bearingless pediatric blood pump, the Abbott PediMag, by creating an innovative, multifunctional, and advanced compact ECLS...
- This Project Grant award, funded by the National Heart, Lung, and Blood Institute (NHLBI) under the Cardiovascular Diseases Research program (CFDA 93.837), supports the development of unfixed, immune-compatible, and regenerative xenogeneic biomaterials for transcatheter heart valve replacements by Vivita Technologies, Inc. (Davis, CA). The $496,255 award aims to validate Vivita's patented SPEAR Platform™ technology, which produces "BARE™ patches" that avoid rapid immune destruction...
- This federal Project Grant award from the National Heart, Lung, and Blood Institute (NHLBI) under the Cardiovascular Diseases Research program (CFDA 93.837) provides $455,826 to conduct a double-blind, randomized, placebo-controlled trial to determine the effects of chronic sildenafil administration on vascular remodeling during left ventricular assist device (LVAD) support. The study aims to assess the impact of sildenafil, a phosphodiesterase-5 inhibitor, on aortic stiffness, carotid...
BLOOD TRAUMA, VASCULAR REMODELING, AND VASOREGULATION WITH TOTAL BODY CONTINUOUS VERSUS PULSATILE ARTIFICIAL CIRCULATION - PROJECT ABSTRACT LEFT VENTRICULAR ASSIST DEVICE SUPPORT IS STANDARD THERAPY FOR PATIENTS WITH ADVANCED, LIFE-THREATENING HEART FAILURE. HOWEVER, CURRENT-GENERATION IMPELLER-BASED BLOOD PUMPS HAVE INTRODUCED A NEW "NON-PULSATILE" PHYSIOLOGY WITH FREQUENT ADVERSE EVENTS. LACK OF PULSATILITY CONTRIBUTES TO BLOOD TRAUMA, ENDOTHELIAL AND ARTERIAL REMODELING, AND ABNORMALITIES IN VASOREGULATION THAT PREDISPOSE PATIENTS TO BLEEDING, THROMBOSIS, DIASTOLIC HYPERTENSION, AND STROKE. CYCLIC SPEED MODULATION IN WHICH DEVICE IMPELLER SPEED IS RAPIDLY INCREASED/DECREASED HAS BEEN DEVELOPED TO GENERATE PULSATILE BLOOD FLOW. THIS EMERGING TECHNOLOGY HAS POTENTIAL TO COMBINE DURABILITY OF IMPELLER-DRIVEN DEVICES WITH PHYSIOLOGIC BENEFITS OF PULSATILITY IN ORDER TO REDUCE ADVERSE EVENTS AND IMPROVE QUALITY OF LIFE FOR PATIENTS WITH ARTIFICIAL CIRCULATION DEVICES. TO DATE, NO INVESTIGATION HAS CHARACTERIZED (PATHO)PHYSIOLOGIC EFFECTS OF TOTAL-BODY PULSATILE VERSUS NON-PULSATILE BLOOD FLOW WITH THE SAME DEVICE. THE BIVACOR TOTAL ARTIFICIAL HEART IS A FIRST-OF-ITS-KIND, IMPELLER-BASED TOTAL ARTIFICIAL HEART WITH THE ABILITY TO GENERATE CONTINUOUS (NON-PULSATILE) OR PULSATILE BLOOD FLOW THROUGH CYCLIC IMPELLER SPEED MODULATION. IN A CHRONIC BOVINE MODEL, WE PROPOSE TO INVESTIGATE IN VIVO EFFECTS OF NON-PULSATILE VERSUS PULSATILE FLOW WITH THE BIVACOR ON BLOOD TRAUMA, ARTERIAL REMODELING, AND VASOREGULATION. WE ANTICIPATE THAT COMPARED TO NON-PULSATILE SUPPORT, PULSATILE FLOW WILL 1) REDUCE BLOOD TRAUMA, 2) PREVENT PATHOLOGIC CHANGES IN ENDOTHELIAL AND ARTERIAL WALL ARCHITECTURE AND FUNCTION, AND 3) MAINTAIN NORMAL VASOREGULATION DURING POSTURAL CHANGES, TRANSITION TO EXERCISE, SLEEP, AND OTHER ACTIVITIES OF DAILY LIVING. DATA WILL PROVIDE INSIGHT INTO PATHOPHYSIOLOGIC MECHANISMS OF ADVERSE EVENTS IN PATIENTS WITH IMPELLER-BASED BLOOD PUMPS. FINDINGS WILL ALSO BE USEFUL FOR THE DEVELOPMENT OF ARTIFICIAL PULSATILITY ALGORITHMS THAT MIMIC PHYSIOLOGIC PULSATILITY IN ORDER TO MINIMIZE BLOOD TRAUMA, PREVENT ARTERIAL REMODELING, AND APPROPRIATELY MODULATE VASOMOTOR TONE DURING DAILY ACTIVITIES.
