SURGICAL STAPLING DEVICE
First Claim
1. A surgical stapling device, including:
- an elongated body portion having proximal and distal portions; and
a head portion positioned adjacent the distal portion of the body portion, the head portion including;
a shell assembly; and
an anvil assembly movable relative to the shell assembly along a longitudinal axis between unapproximated and approximated positions, the anvil assembly including an anvil head and a center rod extending proximally from the anvil head, the center rod including a plurality of receiving structures each configured and dimensioned to receive a flexible member securable to tissue to selectively draw tissue into the shell assembly during approximation of the anvil assembly and the shell assembly, the center rod including a marker positioned between the receiving structures in a location indicating an amount of tissue to be drawn into the shell assembly, the marker being visually distinct from both an outer surface of the center rod, and from the receiving structures.

Abstract
A surgical stapling device an elongated body portion having proximal and distal portions, and a head portion positioned adjacent the distal portion of the elongated body portion. The head portion includes a shell assembly and an anvil assembly movable relative to the shell assembly between un-approximated and approximated positions. The anvil assembly includes a center rod and an anvil head connected to the center rod. The center rod includes at least one aperture extending transversely therethrough and configured and dimensioned to receive a flexible member such that the flexible member extends transversely through the center rod.

12. An anvil assembly movable in relation to a shell assembly of a surgical stapling device, the anvil assembly comprising:
-
an anvil head; and a center rod extending proximally from the anvil head, the center rod including a plurality of receiving structures each configured and dimensioned to receive a flexible member securable to tissue to selectively draw tissue into the shell assembly, the center rod including a marker positioned between the receiving structures in a location indicating an amount of tissue to be drawn into the shell assembly, the marker being visually distinct from both an outer surface of the center rod, and from the receiving structures. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A head portion of a surgical stapling device, the head portion comprising:
-
a shell assembly; and an anvil assembly movable relative to the shell assembly, the anvil assembly comprising; an anvil head; and a center rod extending proximally from the anvil head, the center rod including a proximal receiving structure, a distal receiving structure, and an intermediate receiving structure positioned between the proximal receiving structure and the distal receiving structure, each of the receiving structures being configured and dimensioned to receive a flexible member securable to tissue to selectively draw tissue into the shell assembly during approximation of the shell assembly and the anvil assembly, the center rod including a marker positioned between the proximal receiving structure and the intermediate receiving structure in a location indicating an amount of tissue to be drawn into the shell assembly, the marker being visually distinct from both an outer surface of the center rod, and from each of the receiving structures. - View Dependent Claims (20)
