Abstract

A buttress for use with circular surgical staplers that does not require adhesive to securely fasten the buttress to the stapler. Following cutting and stapling by the circular stapler, the buttress has an adaptive opening through its central region with a diameter smaller than the outer diameter of the stapler anvil. Because of relief features built into the buttress, the stapler anvil may be pulled through the buttress material without causing permanent alteration to the buttress. These relief features may be provided regardless of whether the buttress is made of inelastic or elastic materials. The buttress is generally circular in shape with an outer diameter sized to coincide with the outer diameter of the stapler body staple compression surface and the outer diameter of the anvil compression surface of a circular stapler with which it is used. Prior to surgical use, the buttress is attached to the stapler with disruptable portions extending from outer perimetal areas of the buttress.

Claims

1. A circular staple line reinforcement device comprising a buttress material having at least one relief feature therein and a central opening.

2. The device of claim 1 wherein the relief feature is a slit.

3. The device of claim 1 wherein the relief feature is a straight form.

4. The device of claim 1 wherein the relief feature is of a form other than straight.

5. The device of claim 1 wherein the relief feature is an opening.

6. The device of claim 1 wherein the relief feature is serpentine shaped.

7. The device of claim 1 wherein the relief feature comprises at least one corrugation.

8. The device of claim 1 wherein the relief feature comprises at least one hole therein.

9. The device of claim 1 wherein the relief feature is a series of openings oriented radially.
