... of this study is to evaluate several catheters using time-action analysis during a navigation task in bifurcations of various geometries. The relation between the geometry of bifurcations, the catheters, and the time taken to perform specific actions is investigated. Nine novices manipulated five widely used...

.... The CAM vessels of a developing chicken embryo have been shown to be an appropriate model for human retinal veins. The effect of microneedle geometry and vessel size on puncture forces was investigated. The results of this work are important for researchers working on robotic vitreoretinal surgical...
