First Claim
Patent Images
1. An anvil assembly for use with a surgical fastener applying apparatus, the anvil assembly comprising:
- an anvil head defining a longitudinal axis and formed from a first material; and
an anvil plate supported by the anvil head and including a plurality of fastener pockets, the anvil plate being formed from a second material different from the first material and selected from the group consisting of steel, titanium, magnesium, aluminum, and zinc alloy.

Abstract
An anvil assembly for use therewith a surgical fastener applying apparatus including an anvil plate and an anvil head configured and dimensioned to support the anvil plate. The anvil plate and the anvil head may be formed from different materials. The anvil plate can include a tapered outer side wall allowing the anvil assembly to realize a substantially uniform proximal-most surface upon assembly.

12. A method of manufacturing an anvil assembly for use with a surgical fastener applying apparatus, the method comprising the steps of:
-
providing an anvil head defining a longitudinal axis; providing an anvil plate including an outer side wall that tapers towards the longitudinal axis of the anvil head such that an acute angle is defined between the outer side wall and the longitudinal axis; positioning the anvil head and the anvil plate in contacting relation; and deforming a portion of the anvil head towards the anvil plate to fixedly secure the anvil head and the anvil plate together such that the anvil assembly includes a substantially uniform proximal-most surface. - View Dependent Claims (13, 14)

15. A surgical fastener applying apparatus, comprising:
-
a surgical fastener retention assembly including a plurality of surgical fasteners each having first and second legs; and an anvil assembly including a tissue contacting surface with a plurality of fastener pockets formed therein each including a pair of cavities configured and dimensioned to receive corresponding legs of one of the surgical fasteners, the cavities being connected by a linear section including a pair of arcuate forming surfaces each configured and dimensioned to engage and redirect a corresponding leg of the surgical fastener to thereby achieve a formed configuration of the surgical fastener, the cavities being substantially spherical in configuration to provide increased surface area configured and dimensioned for contact with corresponding legs of the surgical fastener to guide the legs of the surgical fasteners into contact with the arcuate forming surface. - View Dependent Claims (16, 17, 18, 19, 20, 21)
