At least one of the first and second jaw members (12, 14) includes scoring structure (20) capable of scoring calcifications or tissue or any other anatomical structure, with a direction of a scoring force along a jaw closing axis (25) that extends between surfaces (22, 24) of the first and second jaw members (12, 14), respectively, which face each other. The first jaw member (12) has a cutting element (18) arranged to cut in a cutting direction (27) transverse to the jaw closing axis (25). ## Claims ### Claim 1 A transcatheter device comprising: a first jaw member, a second jaw member and a linkage mechanism coupled to said first and second jaw members for changing a distance between said first and second jaw members; at least one of said first and second jaw members comprising scoring structure capable of scoring calcifications or tissue or any other anatomical structure, wherein a direction of a scoring force applied by said scoring structure is along a jaw closing axis that extends between surfaces of said first and second jaw members, respectively, which face each other; and wherein said first jaw member comprises a cutting element arranged to cut in a cutting direction transverse to said jaw closing axis. ### Claim 2 (depends on 1) The transcatheter device according to claim 1, wherein said linkage mechanism comprises one or more wires wrapped around a pivot member which is coupled to said first jaw member, a distal end of said one or more wires being coupled to said second jaw member, and wherein movement of a proximal end of said one or more wires in a proximal direction reduces a distance between said first and second jaw members. ### Claim 3 (depends on 1) The transcatheter device according to claim 1, wherein said cutting direction is along a distal-proximal axis of the device. ### Claim 4 (depends on 1) The transcatheter device according to claim 1, wherein said cutting direction is perpendicular to said jaw closing axis. ### Claim 5 (depends on 1) The transcatheter device according to claim 1, wherein said scoring structure comprises sharp or non-sharp protrusions or any combination thereof. ### Claim 6 (depends on 1) The transcatheter device according to claim 1, wherein said cutting element comprises a sharp edge movable past a sharp edge of said first jaw member. ### Claim 7 (depends on 1) The transcatheter device according to claim 1, wherein said cutting element is a rotational cutting element. ### Claim 8 (depends on 1) The transcatheter device according to claim 1, wherein said cutting element is an oscillating cutting element. ### Claim 9 (depends on 1) The transcatheter device according to claim 1, wherein said cutting element is shaped as a tube with a longitudinal cutout portion. ### Claim 10 (depends on 1) The transcatheter device according to claim 1, further comprising a cutter mover coupled to said cutting element. ### Claim 11 (depends on 1) The transcatheter device according to claim 1, wherein a distal end of said first jaw member is formed with a cutout window, which defines a sharp edge of said first jaw member. ### Claim 12 (depends on 1) The transcatheter device according to claim 1, wherein a distal end of said first jaw member comprises a distal stop to limit a travel of said cutting element.
