1. A device, comprising:
a work element, the work element comprising:
a tube comprising, at a distal end thereof, at least one articulable scoop-like structure, the at least one articulable scoop-like structure being configured to press against a wall of a vascular structure to isolate a work area within the vascular structure from areas proximal and distal thereto; and
at least one rotatable articulable beak, disposed co-axially within the tube, the at least one articulable beak being separate from and independently rotatable relative to the at least one articulable scoop-like structure, the at least one articulable beak comprising a plurality of surfaces that define voids that form a first tendon, a second tendon and a first living hinge disposed between the first tendon and the second tendon, the at least one articulable beak being configured to selectively open and close against the at least one scoop-like structure as the living hinge flexes and to cut tissue within the isolated work area,
wherein the at least one articulable scoop-like structure comprises at least one second living hinge and at least one third tendon that are configured to enable the at least one articulable scoop-like structure to articulate and press against the wall of the vascular structure independently of the at least one articulable beak.
