Abstract:
A device including:(a) a shaft having at least one flexible portion along its length between a proximal end and a distal end; (b) at least two longitudinally bendable pulling and/or pushing elements acting on the shaft in an axial direction of the shaft at different distances from the proximal end of the shaft, the at least two pulling and/or pushing elements each extending to the proximal end of the shaft; (c) a fixing device located in a fixed position with respect to the shaft adjacent to the proximal end of the shaft, the fixing device having each of the at least two pulling and/or pushing elements extending there through, and being adapted to reside alternatively in a releasing position in which the pulling and/or pushing elements are unsecured to the fixing device and are substantially free to move axially there through, or a locking position in which each pulling and/or pushing element is fixed in place with respect to the fixing device; (d) an elongated tip having a proximal end connected to the distal end of the shaft and a distal end extending from the shaft; and (e) a tip control device located adjacent to the proximal end of the shaft and connected to the elongated tip for controlling the longitudinal form of the elongated tip.
