NIH grant funds development of pediatric feeding tube placement device

Researchers at Children’s National Hospital have received grant funding from the National Institute of Diabetes and Digestive and Kidney Diseases, within the National Institutes of Health (NIH), to finalize development of the Pediatric PUMA-G System, the world’s first and only ultrasound-based procedure for placing feeding tubes into the stomach. The funding will also support the first clinical trial of this technology in pediatric patients.

“Children’s National was chosen because we have a strong record of innovating pediatric devices and surgical procedures through the Sheikh Zayed Institute and we have a busy clinical interventional radiology service,” says Karun Sharma, M.D., Ph.D., director of Interventional Radiology and associate director of clinical translation at the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI) at Children’s National. “We are proud to be a part of this collaboration that will potentially help improve care of pediatric patients who cannot tolerate feeding by mouth.”

The feeding tubes are vital for children who cannot eat or swallow and require liquid nutrition (known as enteral feeding). Common feeding tube placement procedures for children may expose them to risks from invasive surgical tools or from ionizing radiation, which may lead to cancer in young patients at elevated rates. The PUMA-G System is less invasive and uses ultrasound to help physicians image the body during the procedure.

The grant, totaling $1.6M, will clinically evaluate the Pediatric PUMA-G System in collaboration with CoapTech, a biotechnology medical device company and two other premier pediatric medical centers — New York-Presbyterian Morgan Stanley Children’s Hospital and Children’s Hospital of Philadelphia.
