Abstract:
1. An anvil assembly comprising an anvil shaft and an anvil head, the anvil shaft movable longitudinally to move the anvil head longitudinally between distal and proximal positions, the anvil head having anvil depressions for forming surgical staples, the anvil head mounted to the anvil shaft, the anvil shaft having a longitudinal axis and first and second spaced apart elongated projections fixedly attached to the anvil shaft to prevent all movement of the projections in relation to the anvil shaft, wherein longitudinal movement of the anvil shaft moves the projections longitudinally, the first projection having a first end fixedly attached to the anvil shaft and extending outwardly with respect to the anvil shaft and the second projection having a second end fixedly attached to the anvil shaft and extending outwardly with respect to the anvil shaft, the first end being spaced axially distally along the longitudinal axis from the second end such that the first end is closer to the anvil head than the second end, the projections forming multiple spaced apart purse-string suture capturing regions along the shaft.
