The poor contractility of the detrusor muscle in underactive bladders (UABs) fails to increase
the pressure inside the UAB, leading to strenuous and incomplete urination. However,
existing therapeutic strategies by modulating/repairing detrusor muscles, eg,
neurostimulation and regenerative medicine, still have low efficacy and/or adverse effects.
Here, we present an implantable magnetic soft robotic bladder (MRB) that can directly apply
mechanical compression to the UAB to assist urination. Composed of a biocompatible …
