Abstract

A measurement system for assisting in guiding a tubular-shaped medical device in a body includes a multicore fiber for insertion into a tubular-shaped medical device such that a position of the tip of the multicore fiber corresponds with a position near the tip of the tubular medical device. A plurality of Bragg gratings is inscribed in the multicore fiber. The plurality of Bragg gratings is spaced apart from each other and positioned along the length of the multicore fiber. A measurement device for reading out optical signals is obtained as a function of a total length of a multicore fiber portion inserted in the body. The measurement device is adapted for deriving shape information of the multicore fiber when the multicore fiber is inserted.
