Abstract

Articles are provided having no orientation or a multi-directional orientation. Such articles may be in the form of films, ribbons, sheets, and/or tapes and may be utilized as buttresses with a surgical stapling apparatus or as reinforcing means for suture lines. The articles may be produced with etchings on at least a part of a surface of the article.

First claim

What is claimed is:

1. A reinforcing material comprising a buttress formed of a polymeric film which possesses no orientation or a multi-directional orientation and includes at least one of glycolide, lactide, dioxanone, trimethylene carbonate, and caprolactone, wherein the buttress comprises etched portions which extend parallel and continuously along an entire length of the buttress to increase a surface area of the reinforcing material.

2. The reinforcing material of claim 1 , wherein the etched portions create an etched pattern selected from the group consisting of lines, wells, troughs, channels, and combinations thereof.

3. The reinforcing material of claim 1 , wherein the etched portions further comprise a bioactive agent.

4. The reinforcing material of claim 1 , wherein the etched portions allow for expansion of the buttress in at least one direction.

5. The reinforcing material of claim 1 , wherein the etched portions create a reservoir for containment of a bioactive agent.

6. The reinforcing material of claim 1 , wherein the etched portions alter a degradation profile of the reinforcing material.

7. The reinforcing material of claim 1 , wherein the etched portions increase flexibility in at least one direction of the reinforcing material.

8. The reinforcing material of claim 1 , wherein the etched portions create a pattern on at least one surface of the reinforcing material.

9. An article comprising: a polymeric film which possesses no orientation or a multi-directional orientation, includes at least one of glycolide, lactide, dioxanone, trimethylene carbonate, and caprolactone, and includes an etched pattern on a surface thereof which extends parallel and continuously along an entire length of the polymeric film to increase a surface area of the article.

10. The article of claim 9 , wherein the pattern is created via laser etching.

11. The article of claim 9 , wherein the pattern includes a bioactive agent and a barrier layer positioned over the etched pattern to control the release of the bioactive agent from the article.

12. The article of claim 9 , wherein the pattern increases flexibility in at least one direction of the article.

13. The article of claim 9 , wherein the pattern is selected from the group consisting of lines, wells, troughs, channels, and combinations thereof.

14. The article of claim 9 , wherein the pattern alters the degradation of the article.
