Abstract:
1. A system, comprising: an elongate instrument having a proximal end, a distal end and at least one lumen defined therein; a shape sensing fiber comprising a first portion and a second portion, wherein at least the first portion of the shape sensing fiber is positioned in the at least one lumen of the elongate instrument; and an anchor slide fixed to at least the second portion of the shape sensing fiber, wherein the anchor slide is axially movable but prevented from vertical, yaw, and pitch movement, wherein the anchor slide reduces axial strain on the shape sensing fiber, and wherein the anchor slide is a registration point for matching a coordinate system of the shape sensing fiber to a coordinate system of the elongate instrument or a known structure to register the shape sensing fiber to the elongate instrument or a known structure.
