In previous work, milli-swimmers have proved capable of accomplishing tasks in vitro like the abrasion of blood clots. This project is an exploration of the further capabilities and performance of these milli-scale swimmers. One conceptual design explores the ability for a device to deliver and place a stent, enabled by a flexible 3D printed profile. Variations of swimmer designs were fabricated and tested experimentally to compare with simulated models. Simulations using computational fluid dynamics software and the Navier Stokes equations were performed in order to predict the angular velocity needed to keep each design suspended at a neutral position in a blood-mimicking fluid. This velocity is used to judge performance of the swimmers in order to isolate variables that most influence their navigational ability. These parameters may be used in an automated design optimization so that specialized devices can be made for various purposes and patient needs. Further work in this field could potentially enable new types of surgery with highly specialized biomedical devices being used at smaller scales than have been accomplished before.en-USThe author of this work is the copyright owner.
