Abstract
The present invention is an injectable medical device useful for replacing natural lubricating fluids in the body of humans or animals. The method and composition can be used for the treatment of joints and other parts of the body wherein natural lubrication between surfaces is deficient or where additional lubrication is required. The composition comprises a hydrophilic polymer suspended in a hydrophobic carrier so that the suspension is easily injectable into the desired body part. After injection, the carrier diffuses away from the polymer and is replaced by aqueous body fluids thereby causing the polymer to absorb or adsorb water forming a viscous, lubricating fluid.
Claims12
A composition for supplementing natural lubricating fluids in a human or animal comprising an effective amount of solid, hydrophilic, synthetic polymer particles suspended by being mixed into a liquid, non-aqueous carrier to form a non-viscous suspension, wherein the composition is essentially free of water, and wherein the particles form a viscous lubricating liquid when injected into the human or animal.
