A composition comprising
- a sterile solution of solubilized collagen in a concentration of greater than 5 and less than or equal to 50 mg/ml and having a viscosity of 1,000-200,000 centipoise, a buffer wherein the composition has an osmolarity of 280-350 mOs/kg, wherein the composition is free of crosslinking agent.
A quick set composition comprising
- a sterile solution of solubilized collagen in a concentration of greater than 5 and less than or equal to 50 mg/ml and having a viscosity of 1,000-200,000 centipoises and a pH of 6.8-8.0, wherein the solution has an osmolarity of 280-350 mOs/kg, wherein the solution sets into a scaffold within 10 minutes of exposure to temperatures of greater than 30° C.
A compressible expandable scaffold, comprising a collagen sponge, wherein the collagen is type I soluble collagen and collagen is in a concentration of grater than 5 and less than or equal to 50 mg/ml, wherein the collagen sponge is free of crosslinking agent.
