1. A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable and an anvil portion that is selectively movable between open and closed positions, said staple cartridge comprising:

  • a cartridge body supportable within the stapling device for selective confronting relationship with the anvil portion thereof when in a closed position, said cartridge body configured to receive the actuator therein;

    a first staple, comprising;

    a crown comprised of a dissolvable material;

    a first deformable member; and

    a second deformable member, said crown connecting said first member and said second member when said crown is undissolved, said first member being unconnected to said second member after said crown has been dissolved;

    a first staple driver movably supported within said cartridge body for contact by the actuator such that, as the actuator is advanced through said cartridge body, said first staple driver is driven toward the anvil when the anvil is in the closed position, said first staple driver defining a first staple support cradle therein for supporting said first staple thereon, said first staple support cradle located a first staple forming distance from a corresponding portion of the closed anvil;

    a second staple; and

    a second staple driver movably supported within said cartridge body for contact by the actuator such that, as the actuator is advanced through said cartridge body, said second staple driver is driven toward the anvil when the anvil is in the closed position, said second staple driver defining a second staple support cradle therein for supporting said second staple thereon, said second staple support cradle located a second staple forming distance from another portion of the closed anvil, wherein said second staple forming distance differs from said first staple forming distance.
