One company aims to reduce pain in a pediatric medical procedure, while the other seeks to lower unnecessary antibiotic prescriptions.

The grants will assist Actuated Medical in developing a device to improve bone biopsies and bone marrow aspirations in children, and ENTvantage Diagnostics in developing a more accurate tool to diagnose sinus infections in children, and thereby reduce inappropriate use of antibiotics.

Funded by the U.S. Food and Drug Administration and based at The Children’s Hospital of Philadelphia, the PPDC provides know-how and seed funding to help innovators translate promising ideas into commercial medical devices for use in children.

The new round of awards is the second by the PPDC, following a group of three $25,000 seed grants announced in February 2015 to innovative firms that applied to the Consortium’s first request for proposals in June 2014.

"We are excited to provide these funds to innovators of promising medical devices that will address unmet clinical needs of pediatric patients around the world," said bioengineer Matthew R. Maltese, Ph.D., of The Children’s Hospital of Philadelphia, the Consortium’s executive director and principal investigator.

A bone access system proposed by Actuated Medical, of Bellefonte, Pa., aims to reduce patient discomfort, improve the success rate for first-attempt samples, reduce clinician fatigue, and shorten procedure times for bone biopsy and bone marrow aspiration procedures. Physicians performing these procedures on children currently face multiple challenges.

This patient population requires deep sedation or anesthesia to tolerate bone access procedures. Children also have small, curved bones, which increase the risk of needle slippage and damage to surrounding tissue.

The lack of CT or other image guidance during pediatric bone access increases the difficulty of maintaining the desired needle trajectory, which results in failed access and repeated insertions, as well as increased post-operative pain and risk of infection. This new device under development will reduce insertion force and needle slippage, allowing for faster and more reliable bone penetration.
