1. A surgical fastener applying apparatus, comprising:
- a cartridge half-section having at least one upstanding plate extending from an upper surface of the cartridge half-section, wherein the upstanding plate is located near a proximal end thereof and defines a channel formed therein; and
an anvil half-section selectively matable with the cartridge half-section, wherein said cartridge and anvil half-sections are relatively movable from an unmated position to a mated position with one another, the anvil half-section supporting a pin configured for selective engagement in the channel of the upstanding plate, the pin having a body portion and a head portion extending radially outward from the body portion, the pin limiting an angle at which the cartridge half-section and the anvil half-section are properly mateable wit one another from a position where they are separate and not in contact, and wherein the body portion of the pin defines a longitudinal axis and the head portion of the pin defines a longitudinal axis, and wherein the longitudinal axis of the body portion of the pin is spaced from the longitudinal axis of the head portion of the pin.

6. A surgical fastener applying apparatus, comprising:
-
a cartridge half-section having an upstanding plate extending from an upper surface of the cartridge half section, wherein the upstanding plate is located near a proximal end thereof and defines an open ended channel formed therein; and an anvil half-section selectively matable with the cartridge half-section, wherein said cartridge and anvil half-sections are relatively movable from an unmated position to a mated position with one another, the anvil half-section supporting a pin selectively receivable in the channel of each upstanding juxtaposed plate, the pin having a body portion defining a length and a head portion extending radially outward from the body portion and extending along at least a portion of the length of the body portion, the pin limiting an angle at which the cartridge half-section and the anvil half-section are properly mateable wit one another from a position where they are separate and not in contact, and wherein the cartridge half-section and anvil half-section are pivotable relative to one another about an axis of the body portion of the pin when the pin is inserted into the channels of the pair of upstanding plates. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
