SINGLE LOOP SURGICAL FASTENER APPARATUS FOR APPLYING VARIABLE COMPRESSION
First Claim
1. A surgical fastener applying apparatus comprising a first jaw and a second jaw, the first jaw containing a first row of first surgical fasteners and a second row of second surgical fasteners, the second jaw containing a first row of first anvil pockets and a second row of second anvil pockets, the first and second rows of anvil pockets deforming the respective first and second rows of fasteners, at least one of the first fasteners having a first unformed length and forming a single loop configuration having a first formed length to form a first compressive space when deformed by the anvil pocket, and at least one of the second fasteners having a second unformed length and forming a single loop configuration having a second formed length to form a second compressive space when deformed by the anvil pocket, wherein the first unformed length is less than the second unformed length and the first formed length is less than the second formed length.

Abstract
A surgical fastener applying apparatus comprising a first jaw containing a first row of first surgical fasteners and a second row of second surgical fasteners and a second jaw containing a first row of first anvil pockets and a second row of second anvil pockets deforming the respective first and second rows of fasteners. At least one of the first fasteners has a first unformed length and a first formed length forming a single loop configuration to form a first compressive space when deformed by the anvil pocket. At least one of the second fasteners has a second unformed length and a second formed length forming a single loop configuration having a second compressive space. The first unformed length and first formed length of the at least one first fastener is less than the second unformed length and second formed length of the at least one second fastener.

- 13. A surgical fastener applying apparatus comprising a fastener assembly having a first pair of first rows of fasteners and a second pair of second rows of fasteners and a corresponding first pair of rows of anvil pockets and a second pair of rows of anvil pockets to deform the respective fasteners, wherein at least one of the fasteners of the first pair of rows of fasteners when formed into a single loop configuration applies a first compressive force on tissue and at least one of the fasteners of the second pair of rows of fasteners when formed into a single loop configuration applies a second different compressive force on tissue.
- 18. A surgical fastener applying cartridge and anvil assembly for use with a surgical fastener applying instrument, the cartridge and anvil assembly comprising a cartridge having a first pair of first rows of fasteners and a second pair of second rows of fasteners and an anvil having a first pair of rows of anvil pockets and a second pair of rows of anvil pockets, wherein at least one of the fasteners of the first pair of rows of fasteners when formed into a single loop configuration applies a first compressive force on tissue and at least one of the fasteners of the second pair of rows of fasteners when formed into a single loop configuration applies a second different compressive force on tissue.
