Abstract
Official abstract text for this publication.
Provided are compositions and methods that involve viscoelastic poly(lactide-co-caprolactone) (PLCL) mixtures for use in wound healing. The PLCL mixtures provide an improved anti-fibrotic yet tissue-adhesive polymer sealant. The PLCL mixtures can be applied to a variety of wounds arising from surgical and non-surgical tissue damage.
First claim
Opening claim text (preview).
What is claimed is: 1 . A composition consisting essentially of a mixture of 40 k and 5 k poly(L-lactide-co-caprolactone) (PLCL), wherein the 40 k and 5 k PLCL are present in a 70:30 mass ratio, respectively, wherein the composition is free of poly(lactic-co-glycolic acid) (PLGA), poly(ethylene glycol) (PEG) and nanoparticles, and when in contact with a tissue wound the composition is optionally a solid adhesive.
