Abstract
A medical instrument includes a nested conduit extending through an elongate flexible body. A tendon extends through an inner lumen of the inner conduit. A first control element is coupled to the outer conduit and a second control element is coupled to the inner conduit. Each of the first and second control elements is adjustable between a first state and a second state. The outer conduit is axially constrained proximate the first control element in the first state of the first control element and is not axially constrained in the second state. The inner conduit is axially constrained proximate the second control element in the first state of the second control element and is not axially constrained in the second state. An articulatable length of the nested conduit is variable based on adjustment between the first and second states of the first control element and the second control element.
