CONCEPTION D'UNE LUMIÈRE PERMETTANT UNE INTÉGRATION OPTIMALE D'UNE FIBRE EN VUE D'UNE DÉTECTION OPTIQUE DE FORME ET MÉTHODE DE DETECTION DE FORME ASSOCIÉE
A shape sensing enabled instrument includes a flexible longitudinal body (300) including a plurality of longitudinal members (310) held together to form a lumen (205). The longitudinal members have frictional contact therebetween and are configured to engage neighboring longitudinal members during bending, twisting or external pressure to maintain dimensions of the lumen. A shape sensing optical fiber (302) is disposed within the lumen.
