Abstract

Systems and methods for controlling patient catheters are disclosed. A system in accordance with a particular embodiment includes a catheter carrying multiple active elements, and a controller connected to the catheter. The controller can include a housing having directional indicators, and multiple control elements coupled to the multiple active elements. Individual control elements can be moveable relative to the housing to control the motion of the active elements, and the multiple control elements can be positioned so that manipulation of the multiple control elements in a first order that is clockwise or counterclockwise as identified by the directional indicators moves the multiple active elements in a first manner, and manipulation of the multiple control elements in a second order opposite the first order moves the multiple active elements in a second manner opposite the first manner.
