    Insights

    Pediatric heart failure (HF) treatment needs better blood pumps. This study develops a miniaturized wireless power system for the Jarvik 2000 Child blood pump, improving implantability and reducing infection risk.

    Area of Science:

    • Biomedical Engineering
    • Pediatric Cardiology
    • Medical Device Development

    Background:

    • Heart failure (HF) affects thousands of children annually in the US.
    • Current blood pump technology for children lags behind adult advancements, hindering implantability.
    • Existing wireless powering transfer systems (WPTS) are too large for pediatric use.

    Purpose of the Study:

    • To develop a miniaturized, fully implantable wireless powering transfer system (WPTS) for the Jarvik 2000 Child blood pump.
    • To address the limitations of current pediatric circulatory support devices.
    • To improve outcomes for children with heart failure.

    Main Methods:

    • Design of thin (36 um) planar coils for behind-the-ear implantation.
    • Development of an amplifier and rectifier circuit.
    • Integration of the WPTS with the Jarvik 2000 Child blood pump.

    Main Results:

    • Successful design of miniaturized components for pediatric WPTS.
    • Demonstration of a system capable of delivering 15.7V and 0.5A to the blood pump.
    • Preliminary work indicates feasibility for improved blood pump implantability in children.

    Conclusions:

    • The developed wireless powering transfer system shows promise for enhancing pediatric heart failure treatment.
    • Miniaturized WPTS can overcome current limitations in pediatric blood pump technology.
    • This innovation may lead to reduced infections and improved patient outcomes in pediatric HF management.

    Anatomy of the Circulatory System

    The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.

    ATP Driven Pumps III: V-type Pumps01:30

    ATP Driven Pumps III: V-type Pumps

    V-type pumps are ATP-driven pumps found in the vacuolar membranes of plants, yeast, endosomal and lysosomal membranes of animal cells, plasma membranes of a few specialized eukaryotic cells, and some prokaryotes. They are also known as the V1Vo-ATPase, that couple ATP hydrolysis to transport protons against a concentration gradient.
    The peripheral or cytosolic V1 domain with eight subunits is involved in ATP hydrolysis. The integral or transmembrane V0 domain containing at least five subunits...

    ATP Driven Pumps II: P-type Pumps

    The P-type pumps are a large family of integral membrane transporter ATPases. They are divided into five major types based on substrate specificity, from I to V.
    A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...

    Self-Help Support Groups

    Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.

    Pumped Concrete01:13

    Pumped Concrete

    Concrete in large quantities can be pumped across long distances for placing in inaccessible sites. This system comprises a hopper that receives concrete from a mixer, a pump to propel the concrete, and pipelines that facilitate its delivery.
    For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...

    Power01:08

    Power

    The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...
