Abstract: A system is disclosed that includes an optical fiber including a first optical module and a gate. The gate can be capable of moving between closed and opened states to form a slit. At least one storage medium can be included having encoded thereon executable instructions that, when executed by the at least one processor, cause the system to carry out a method including directing light from the first optical module through the slit onto the stone to form a pair of lines with a spacing between the pair of lines; and determining a size of the stone, based on a distance from a distal tip of the optical fiber and the spacing between the pair of lines.

Abstract: Methods and systems for determining and mapping a location of a distal end region of an elongate shaft. An illustrative method may comprise obtaining data from an accelerometer located in the elongate shaft adjacent a distal end thereof, determining a length of the elongate shaft inserted into a body from a reference point, merging the accelerometer data and the length of the elongate shaft to localize the distal end region of the elongate shaft, reconstructing a line of travel of the medical device within the body, and superimposing the reconstructed line of travel over an image of an anatomy of the patient.
