This research aims to enhance chemotherapy delivery using tapered magnetic soft continuum catheters.
Developed a tapered catheter design inspired by octopus tentacles.
Utilized discrete elastic modeling, finite element methods, and material point method simulations.
Tested deflection behaviors under magnetic actuation.
Implemented microchannel networks for targeted drug delivery in a neurovascular tumor model.
The material point method showed higher accuracy in capturing catheter deflections.
Experimental results indicated improved deflection under low magnetic fields.
Tapered designs enhanced localized drug delivery compared to systemic methods.
