Pediatric Implantable heart Project Reinstated After Federal Grant Cancellation and Family Relief
USA: A four-year-old boy in Philadelphia remains tethered to a hospital bed while awaiting a life-saving heart transplant, highlighting a gap in pediatric cardiac care. About one in 100 babies in the United States are born with congenital heart defects, yet there is no implantable artificial heart designed specifically for infants and young children. The child, Caleb Strickland, is being sustained by an external ventricular assist device (VAD) that supports circulation but must remain connected to a bedside machine, preventing discharge and forcing families to live inside the hospital as they wait—sometimes up to a year—for a donor organ.
For nearly two decades biomedical engineer James Antaki has pursued a radically different solution: a surgically implantable pump the size of a double‑A battery intended for babies and toddlers. Unlike the external VAD keeping Caleb hospitalized, Antaki’s device would sit inside the body and could allow young patients to go home while awaiting transplantation. The long‑running project was abruptly halted last April when the Department of Defense, which administers a $6 million multi‑year award, informed Antaki that work must stop at the direction of the administration, citing no further explanation.
Caleb’s mother, Nora Strickland, pressed for answers about why research that might spare other families the strain of prolonged hospital stays was interrupted. Antaki, likewise, said he could not see how the research related to broader political debates referenced by authorities, and both he and the family described the cancellation as devastating for patients who could benefit from the technology.
Following renewed discussions between Cornell University and the White House, the stop‑work order was lifted and the grant has been reinstated. The reinstatement brought relief and disbelief to the researcher and to families following the project, and it restored momentum to efforts aimed at developing an implantable pediatric heart pump that could change how very young patients are bridged to transplant.
