The present invention is directed to bioabsorbable adhesive/hemostatic formulations of a 2-alkoxyalkylcyanoacrylate and liquid or solid polymeric modifiers and adjuvant. The present adhesive formulations are useful as tissue adhesive/sealants, hemostatic agents, and as a means for patching or anastomic coupling of damaged organs.

An adhesive composition for surgical use including an α-cyanoacrylate adhesive composition with a polymer characteristic for biodegrading and bioabsorbing the adhesive into the body of a living organism. It is preferred that the polymer is a co-polymer of DL-lactic acid and ϵ-caprolactone or a co-polymer of DL-lactic acid, ethylene glycol and ϵ-caprolactone, or a co-polymer of ethylene glycol and ϵ-caprolactone.

Tissue adhesive compostions are disclosed which comprise at least one 2-cyanoacrylate ester of the general formula (I) in admixture with from about 2 percent to about 25 percent of at least one oxalic acid polymer of the general formula (II).

Lactic acid has been first introduced to us as early as 1780 as a sour component of milk. Ever since we have found its applications in food, pharmaceutical, cosmetic industries etc. Now there are emerging uses as a potential feedstock for the biodegradable polymer industry. The microorganisms being used for lactic acid fermentation, the raw materials reported, the various novel fermentation processes and its processing methods have been reviewed. The properties and applications of lactic acid, its derivatives and polymer have been discussed.

A solid cyanoacrylate adhesive composition is disclosed which can be applied to a substrate in solid form and which polymerizes into an adhesive polymer upon liquefying. Preferably the solid cyanoacrylate composition liquefies at temperatures slightly above room temperature and polymerizes upon liquification. -caprolactones are used as a solidifying polymer with cyanoacrylate monomers and other additives to form the solid cyanoacrylate adhesive composition.
