A surgical stapling system including a driver and a staple where the driver is connected to the staple. In previous surgical stapling systems, the driver and the staple were not connected. A surgical stapling system in accordance with the present invention may have fewer components, less assembly and manufacturing time, and may accommodate larger staples which are at least partially embedded in the driver. In various embodiments, a surgical stapling system comprises a staple, the staple including a deformable member, and a stapler, the stapler including an anvil, a staple cartridge for removably storing the staple, and a cam movable between a first position and a second position. In these embodiments, the surgical stapling system further comprises a driver attached to the staple, the driver being operatively engaged with the cam to move the staple toward the anvil when the cam is moved between the first position and the second position.

Methods and devices are provided to allow the same component used to access a surgical site to assist in closing the surgical opening in which it was disposed. In one exemplary embodiment a flexible retractor is provided that includes proximal and distal ends and a lumen extending therethrough. A wound closure component is associated with the flexible retractor and is configured to engage tissue adjacent to a surgical incision in which the retractor is disposed and move tissue from one side of the surgical incision toward a second side of the surgical incision to assist in closing the surgical incision. In one embodiment the wound closure component includes strands of suture having hooks disposed on a distal end. In another embodiment the wound closure component includes a ring having hooks disposed around a circumference of the ring. Exemplary methods for closing a surgical opening are also provided.

Circular stapling instruments and anvil assemblies. The anvil assemblies may have collapsible anvil support members that may be inserted through an opening in a patient and then expanded to be attached to an anvil plate assembly that has a staple-forming surface thereon. The anvil support member is attachable to the anvil plate assembly in such a way that when the anvil assembly is coupled to the stapling head of a circular stapler, the staple-forming surface is in substantial registry with the staples supported in the stapling head. A variety of different anvil support members and anvil plate assemblies are disclosed. Various embodiments have a tissue-piercing feature.

A surgical stapling system comprising a first staple, a second staple, and a bridge connecting the first staple and the second staple. In at least one embodiment, the first staple and the second staple are part of a strip of staples. For example, the first and second staples can be included in a strip of staples that includes several staples that are attached end-to-end and/or attached side-by side. In use, the strip, or strips, of staples are inserted into a stapler which can be used to insert the staples into soft tissue, for example, and deform at least a portion of the staples to hold the tissue, or several layers of tissue, together.

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.
