Soft-Robotic Magnetic Microfluidic Catheter for Delivery of Aqueous-Based Dual-Component Embolic Formulations
Transcatheter embolization requires materials that can be steered through tortuous vessels, solidify rapidly in situ, remain clearly visible under fluoroscopy, and, ideally, carry therapeutic cargo without harming tissue. To meet these requirements, we present a fully water-based, two-component PEI-PEG hydrogel delivered through a soft-robotic, microfluidic catheter that keeps the precursors…
