A Stent with “Spines” for Drug Delivery
August 31, 2021 | Terry Sharrer
“Researchers at MIT have developed a kirigami-style stent that can provide localized drug delivery through needle-like projections that pop out when the stent is extended. The ‘spines’ on the stent’s surface deliver drug-loaded microparticles into the surrounding tissue, allowing for sustained drug release for an extended period. The technology is well suited to administering drugs within tubular structures, such as those found in the GI tract, the respiratory system, and blood vasculature.” The spines are retractable for stent removal.
