Tilt top anvil for a surgical fastener device
First Claim
1. An anvil assembly comprising:
- a center rod; and
an anvil head pivotally secured to the center rod, the anvil head being adapted for pivotal movement from an initial tilted reduced profile position to an operative firing position in response to movement of the anvil assembly in relation to a shell assembly of a surgical stapling device.

Abstract
A tilt top anvil assembly is provided for use with a surgical stapling device for performing end-to-end anastomosis of tissue. The tilt top anvil assembly included an anvil head, a center rod and a biasing member. The anvil head is pivotally secured to the center rod about a transverse axis which is offset from the longitudinal axis of the center rod. The biasing member is supported on the anvil assembly at a position to urge the anvil head to a tilted reduced profile position. The anvil assembly includes a first abutment surface which is operatively connected to the anvil head is movable into engagement with a second abutment surface formed on a surgical stapling device during approximation of the anvil assembly to move the anvil head from the tilted reduced profile position to an operative firing position. When the anvil assembly is moved to the unapproximated or spaced position, the biasing member is positioned to return the anvil assembly back to its tilted reduced profile position.
