Peripheral Nerve Injury (PNI) leads to significant motor and sensory impairments, with limited recovery potential in injuries exceeding 3 cm, Conventional treatments often fail to achieve full functional restoration. Suction-based approaches at lesion sites have demonstrated promising outcomes in nerve regeneration. This work presents a novel wireless, magnetically actuated micropump composed of biodegradable materials, such as poly(octamethylene-maleate(anhydride)citrate) (POMaC), for nerve repair applications. The micropump integrates a magnetic ring within its membrane, enabling deflection under alternating magnetic field (4Hz,pm 150mT), generating a net under-pressure of 1.3 kPa within 8 minutes. It provides a potential solution to facilitate nerve healing. ... Read more
