An adjustable stylet includes a core wire having a portion surrounded by a compression member preferably comprised of a flat wire spring. Depending upon the configuration, compression or relaxation of the compression member in response to forces at the tip or handle of the stylet results in adjustments to the characteristics of the stylet. In a first embodiment, the stiffness of the stylet is adjustable. In a second embodiment, the length of the stylet is adjustable. In a third embodiment, both the stiffness and the length of the stylet are adjustable.
