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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
One example of a surgical instrument may include a handle, an end effector, and a shaft that connects the handle to the end effector, where the shaft includes an articulated region. At least one feeder belt may extend through the lumen of the shaft into the end effector, where at least one feeder belt may include at least one staple frangibly connected thereto.
摘要:
A method for anastomosing a first vessel to a second vessel may include connecting an end of the first vessel to the side of the second vessel and creating an opening in the wall of the second vessel from within the lumen of the second vessel, where that opening allows fluid communication between the lumen of the first vessel and the lumen of the second vessel.
摘要:
An anastomosis tool may include a connector holder connected to an anvil. The connector holder may be bifurcated and configured to straddle the graft vessel. The connector holder may be generally U-shaped. The connector holder may be shaped to extend around more than half of the circumference of the graft vessel.

A surgical apparatus may include a staple holder, an anvil connected to and movable relative to the staple holder, and at least one axle extending outward from the anvil; and an overtube slidable relative to the end effector, the overtube including at least one slot defined therein; where each slot receives a corresponding axle. A surgical method for treating tissue of a patient may include providing an end effector that includes a staple holder and an anvil connected to and movable relative to the staple holder, and an overtube slidable relative to said end effector, making an incision in the patient; inserting the end effector and at least part of the overtube through the incision in a first, insertion configuration in which substantially no gap exists between the anvil and staple holder, and moving the overtube relative to the end effector to open the end effector to a second, unclamped position where at least part of the anvil is spaced apart from the staple holder.
