Title : Implantable Wireless Neuroprosthesis for Bladder Control After Spinal Cord Injury: A Brain-Bladder Closed-Loop Interface
Author(s) : Dr. Marcus Johnson, Dr. Yuki Tanaka
Abstract :
Neurogenic bladder dysfunction after spinal cord injury (SCI) severely impacts quality of life. We developed an
implantable, wireless neuroprosthesis establishing a closed-loop interface between cortical bladder sensation areas
and sacral root stimulators. Using electrocorticography (ECoG) decoding of bladder fullness states and real-time
pudendal nerve feedback, the system enabled on-demand, physiological voiding in 6 SCI patients during a 12-month
trial. Participants achieved 85% voluntary voiding success, reduced urinary tract infections by 70%, and eliminated
indwelling catheter dependence in 4 cases. This brain-bladder interface restores autonomic function through
biomimetic neural engineering.
