  • Patent number: 10751040
    Abstract: 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.

  • Publication number: 20200261106
    Abstract: 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.
