摘要：
Flexible elongate device systems and methods include a flexible elongate device having a flexible body and an axial support structure. The axial support structure includes at least one groove extending along a length of the axial support structure. The flexible elongate device further includes a plurality of control elements for actuating the flexible elongate device. Each of the plurality of control elements extends through one of the at least one groove of the axial support structure. In some embodiments, the at least one groove includes a plurality of grooves spaced circumferentially around the axial support structure. In some embodiments, the flexible body includes lumens that extend through the at least one of the grooves. The control elements are disposed in the lumens. In some embodiments, the flexible body includes a main lumen that extends centrally through the flexible body. The main lumen provides a channel for a medical tool.
