One exemplary surgical apparatus may include at least one carrier, staples fixed to a corresponding carrier, and a feeder belt to which at least one carrier is frangibly connected. Another exemplary surgical apparatus may include a staple holder, an anvil movably connected to the staple holder, a feeder belt, where at least part of the feeder belt extends into the staple holder, and staples fixed to and frangibly separable from the feeder belt; where the staples are organized into at least two groups spaced apart from one another; and where at least one staple is deployable to a different closed shape than at least one other staple. Another exemplary surgical apparatus may include a feeder belt, a first plurality of staples fixed directly to and frangibly separable from the feeder belt; a plurality of extension arms extending at least partially in the lateral direction away from the feeder belt; and a second plurality of staples each fixed to an extension arm at a location spaced laterally apart from the feeder belt.

An exemplary surgical apparatus may include a surgical staple deformable from a first configuration to a second, deployed configuration, where the surgical staple includes a first leg and a second leg; where in the second, deployed configuration the surgical staple forms substantially a D-shape. Another exemplary surgical apparatus may include a feeder belt; a surgical staple deformable from a first configuration to a second, deployed configuration, where the surgical staple includes a first leg and a second leg connected to the first leg, where one end of the first leg is frangibly affixed to the feeder belt and one end of said the leg is free; where in the second, deployed configuration the surgical staple forms substantially a D-shape. An exemplary method of treating tissue may include providing a surgical staple; urging the surgical staple into tissue, while the surgical staple has a first shape; and deforming the surgical staple into substantially a D-shape.

An exemplary surgical apparatus may include a flexible articulation insert and at least one feeder belt extending through the articulation insert, where at least some of the staples are frangibly connected to the feeder belt. Another exemplary surgical apparatus may include at least one movable feeder belt; staples fixed to the feeder belt; and a flexible articulation insert having at least one feeder belt passage defined therein, the flexible articulation insert configured to bend through a range of motion; where each feeder belt extends through a corresponding feeder belt passage, and where each feeder belt passage is shaped such that the corresponding feeder belt and staples fixed thereto are slidable along the passage throughout the entire range of motion of the flexible articulation insert.

An exemplary surgical apparatus may include a feeder belt; wings fixed to that feeder belt; and a die into which the feeder belt extends, where relative motion of the die and feeder belt bends at least one wing to transform at least one wing into an unformed staple. An exemplary surgical method for treating tissue of a patient may include providing a surgical instrument including an end effector; placing the end effector adjacent to tissue of a patient; and manufacturing at least one surgical staple within the end effector.

A system for connecting the end of a graft vessel to the side of a target vessel may include an anvil configured to enter the target vessel through an anvil entry hole in the wall of the target vessel; a holder movable relative to the anvil, where that holder may deploy at least one connector through the graft vessel and into the target vessel at a location spaced apart from the anvil entry hole; and at least one sealer that may be detachably connected to the anvil and/or said holder; where at least one sealer may be configured to substantially close the anvil entry hole in the target vessel. A method for performing anastomosis between a graft vessel and a target vessel may include inserting an anvil through the wall of the target vessel into the lumen of the target vessel from outside of the target vessel through an anvil entry hole; connecting an end of the graft vessel to the side of the target vessel with a plurality of connectors at a location spaced apart from the anvil entry hole; creating an opening in the side of the target vessel, where the opening is located within a perimeter defined by the connectors and spaced apart from the anvil entry hole; withdrawing the anvil through the anvil entry hole; and substantially sealing the anvil entry hole.

An exemplary surgical staple may include a base including a first end and a second end; a single tine extending from the second end of the base; and a barb extending from the base at a location between the first end of the base and the second end of the base. An end of such a staple may be frangibly affixed to a feeder belt. Another exemplary surgical apparatus may include at least one staple including a base including a first end and a second end, a first tine extending from the second end of the base, and a second tine extending from the base at a location between the first end of the base and the second end of the base.

A surgical staple for connecting two tubular tissue structures may include a substantially rectangular base having a first edge and a second edge substantially parallel to one another, and a third edge substantially perpendicular to the first and said second edges; and may also include at least three deformable tines extending from the first and second edges of said base; where no tine that extends from the first edge may be positioned at substantially the same distance from the third edge as any said tine that extends from the second edge; and where deformation of the tines secures the tubular tissue structures together.

An exemplary surgical apparatus may include a feeder belt configured as a continuous loop; staples fixed to and shearable from the continuous feeder belt; apertures defined in the continuous feeder belt; and a gear positioned at the distal end of the feeder belt within the continuous loop, where the gear engages at least one of the apertures to move the continuous feeder belt around the gear. Another exemplary surgical apparatus may include a feeder belt; a plurality of staples fixed to and shearable from the continuous feeder belt; and a plurality of teeth defined on the continuous feeder belt. Another exemplary surgical apparatus may include a continuous belt assembly that has a flexible rack with two ends, and a feeder belt with two ends, each end of the feeder belt connected to a corresponding end of the flexible rack; and staples fixed to and shearable from the continuous feeder belt.

A method for closing a patent foramen ovale in the heart tissue of a patient may include percutaneously advancing a connector applicator to the patent foramen ovale, registering the connector applicator with the patent foramen ovale, deploying connectors into heart tissue to close the patent foramen ovale; and percutaneously removing the connector applicator from the heart. One or more anchors may be used to register the connector applicator with the patent foramen ovale. The connector applicator may include a driver having a longitudinal passage therein, where at least part of at least one connector is positioned within said passage.
