New Ultrasound Implant Breakthrough Could Transform Spinal Cord Injury Recovery
American researchers have successfully placed a tiny ultrasound device as a temporary implant at the site of a spinal cord injury in animals to monitor and identify changes in blood flow.
- Johns Hopkins Medicine engineers and surgeons tested the MUSIC device in an animal proof-of-concept study.
- The implant measures the size of a small Band-Aid and is placed during spinal surgery.
- The project received a $13.48 million award from the U.S. Defense Department.
The device, called Multimodal Ultrasound System for Injury Care (MUSIC), is designed to enhance feedback about what happens at and around the injury site during intensive care unit recovery. Researchers developed the tool to support key clinical decisions and minimize complications such as strokes, blindness, or additional movement loss.
Principal investigator Amir Manbachi stated that local biological injuries require local monitoring tools. “When the biology of spinal cord injury is local, our devices should also be able to track and treat local physiology,” Manbachi explained, according to medicalxpress.com.
The implant functions as a mobile MRI device to alleviate the need to move immobile patients frequently during early recovery. The diagnostic aspect delivers real-time data regarding blood flow, spinal fluids, excess fluid accumulation, and medication response.
The therapeutic ultrasound feature explores focused ultrasound technology to respond when blood flow in small vessels around the injury drops or spikes outside acceptable ranges. The system previously secured a Food and Drug Administration breakthrough device designation in 2023.
Findings published in Science Advances demonstrate that the temporary implant is feasible, safe, and potentially useful. Co-creator Nicholas Theodore noted the critical nature of timing for patient recovery.
“Timing is critical for recovery,” Theodore said. “This research represents a fusion of multiple industries, disciplines and applications that we envision has the power to fine-tune and personalize the care that a person receives following their surgery, which could support and improve their health outcomes months and years later.”
Researchers intend to scale the application to assist patients across diverse demographics, including soldiers with battlefield wounds as well as civilians affected by vehicle crashes, falls, and sports accidents.
