There is provided a method of advancing an instrument along a path, comprising: selectively steering a distal portion of the instrument to assume a selected curve along the path; and creating a three dimensional model of the selected curve in the memory of an electronic motion controller. <??>There is also provided a method of advancing an instrument along a path, comprising: attempting more than one time to selectively steer the distal portion of the instrument along the path; selecting a curve from the attempts to selectively steer the distal portion of the instrument along the path; and logging the curve into the memory of an electronic motion controller adapted to control the instrument. <??>Provided also is an apparatus, comprising: an elongated instrument body having a selectively steerable distal portion and an automatically controllable proximal portion, the selectively steerable distal portion being configured to selectively assume a selected curve along a desired path, and the automatically controllable proximal portion being configured to propagate the selected curve along the elongated instrument body as the elongated instrument body is advanced along the selected curve; a proximal handle attached to the elongated instrument body; an electronic motion controller connected to the proximal handle and having an electronic memory; a three dimensional model of the selected curve created in the electronic memory of the electronic motion controller; and a steering control connected the handle for selectively steering the selectively steerable distal portion. <IMAGE> |
