Patent ID: 8524798

Claim:
A multi-state composition for treating a damaged orthopedic structure in situ within a body having a body temperature, the composition having a first state with a first viscosity and a first shape and a second state with a second viscosity and a second shape, wherein the second shape is different than the first shape, wherein the second viscosity is greater than the first viscosity, the composition in the first state with the first viscosity comprising a separate component A and a separate component B outside the body wherein: component A includes one or more polysiloxanes and one or more catalysts including a platinum catalyst; and component B includes one or more polysiloxanes and one or more cross-linking agents; such that when separate component A is subsequently combined with separate component B in the damaged orthopedic structure within the body, the composition cures at the body temperature in situ within the body using the body temperature to facilitate curing thereby transforming component A and component B into a cured composition, the cured composition comprising the second state with the greater second viscosity having a Shore A durometer value in the range of 15 to 90, wherein the cured composition adheres to the damaged orthopedic structure, and wherein when the cured composition is transformed into the second shape defined by the damaged orthopedic structure, and further wherein the cured composition provides structural support to the damaged orthopedic structure, wherein: component A comprises: from 50% to 75% by weight of blended polysiloxanes; from 10% to 30% by weight of amorphous silica; and greater than 0.001% by weight of platinum catalyst; and component B comprises: from 50% to 75% by weight of blended polysiloxanes; from 10% to 30% by weight of amorphous silica; and from 0.5% to 5% by weight of cross-linking agent.
