Embodiments of the present invention provide mesoscale or microscale three-dimensional devices, structures, instruments, and the like. In particular, instruments that are useable in minimally invasive surgery are described that include multiple tools that are deployable from a distal end of one or more housings or retractable into a distal end of one or more housings via the applying of tension to either end of one or more chain or chain-like elements that extend from the proximal end of the one or more housings. |
