The present disclosure provides a kirigami-inspired injectable stent system. The stent systems and methods enable radial/circumferential and longitudinal delivery of an extended release of therapeutics within tubular structures of the body, such as the GI tract and trachea. According to some aspects, a kirigami-based injectable stent system is provided that can enable drug release through deposition of therapeutic-coated needles of the stent in the tubular mucosa, such as often found in the gastrointestinal tract or trachea.

Kirigami-inspired stents for sustained local delivery of therapeutics

Systems and methods related to reconfigurable medical devices are described. In some embodiments, a reconfigurable medical device may include a central core and a plurality of arms. The arms may be rotatably coupled to the central core such that the plurality of arms may rotate outwards away from the central core to selectively reconfigure the reconfigurable device between a retracted configuration and an expanded configuration. In an initial state, the arms may be biased outwards away from the central core into the expanded configuration. When the reconfigurable device is exposed to a temperature greater than a threshold temperature, the arms may be biased towards the central core into the retracted configuration. In some embodiments, a reconfigurable medical device may include therapeutic compound-loaded needles coupled to distal portions of the arms.
