Claim Text:
1. A system comprising: a variable stiffness guidewire including a guidewire body, the guidewire body having a proximal end and a distal end; an actuator interface at the proximal end of the guidewire body and including an inner canister and an outer canister at least partially telescoping relative to one another; a tension cable coupled to the outer canister and coupled to the distal end of the guidewire body, the tension cable movable within the inner canister; and an actuator couplable to the actuator interface and configured to move the outer canister relative to the inner canister to vary the stiffness of the guidewire, wherein the stiffness is adjusted by moving the outer canister distally relative to the inner canister and the actuator includes a crimper configured to maintain the stiffness of the guidewire body at the desired stiffness.
