Post-surgical anti-adhesion device

A method for endoscopic minimization of post-surgical adhesions comprising:

• (i) providing a biocompatable surgical structure including at least two bioabsorbable layers superimposed on a nonbioabsorbable layer, at least one of said bioabsorbable layers including a block copolymer wherein:
• a. about 10 to about 90% by weight of the block copolymer includes at least one block formed from a copolymer having greater than 50 mole percent of trimethylene carbonate;
• and
• b. about 10 to about 90% by weight of the block copolymer is another block formed from a copolymer having greater than 50 mole percent of lactide;
• (ii) inserting said surgical structure into a body cavity through a cannula;
• (iii) super imposing said surgical structure over a wound site;
• and
• (iv) thereby causing minimization of post-surgical adhesions.

A method for endoscopic minimization of post-surgical adhesions in endoscopic surgery comprising:

• (i) providing a biocompatable post-surgical adhesion barrier including at least two bioabsorbable layers wherein one of said layers is a bioabsorbable non-woven fabric and one of said layers is a bioabsorbable layer of a block copolymer, wherein:
• a. about 10 to about 90% by weight of the block copolymer is at least one block formed from a copolymer having greater than 50 mole percent of trimethylene carbonate;
• and
• b. about 10 to about 90% by weight of the block copolymer is at least another block formed from a copolymer having greater than 50 mole percent of lactide;
• (ii) inserting the post-surgical adhesion barrier into a body cavity through a cannula;
• (iii) placing the post-surgical adhesion barrier over an area of trauma;
• and
• (iv) thereby causing minimization of post-surgical adhesions.

A method of preventing formation of post-surgical adhesions comprising:

• (i) providing a biocompatable surgical structure including at least two bioabsorbable layers wherein one of said layers is bioabsorbable non-woven fabric and one of said layers is a bioabsorbable layer of a block copolymer, wherein:
• a. about 10 to about 90% by weight of the block copolymer is at least one block formed from a copolymer having greater than 50 mole percent of trimethylene carbonate;
• and
• b. about 10 to about 90% by weight of the block copolymer is at least another block formed from a copolymer having greater than 50 mole percent of lactide;
• (ii) superimposing said surgical structure over a wound site;
• and
• (iv) thereby preventing formation of post-surgical adhesions.
