A flexible shaft ( 28 ) to be inserted into a channel of a living body provided with a plurality of adjacently abutting cells ( 26 ), the walls ( 30 ) of which are formed from wall sections. For this reason the flexible shaft ( 28 ), which is particularly cost-effective to produce and which demonstrates high flexibility paired with ample stability, is constructed such that in at least one cell ( 26 ) in the cross-section of the wall ( 30 ) a concave wall section ( 44, 46, 48 ) is circumferentially alternated with a corresponding neighboring convex wall section ( 50, 52, 54 ). |
