Patent ID: 8168230

Claim:
A platelet gel obtained from a platelet-rich plasma comprising: a platelet-rich plasma containing at least 1 million platelets per microliter of plasma, an amount of at least one platelet activator that activates the release of platelet growth factors, but is not capable of forming a clot in less than 15 minutes, and at least one biocompatible polymer selected from the group consisting of carbomers, polyalkylene glycols, poloxamers, polyesters, polyethers, polyanhydrides, polyacrylates, polyvinyl acetates, polyvinyl pyrrolidones, polysaccharides, polyethylene glycols, hyaluronic acid, benzyl hyaluronate esters, crosslinked hyaluronic acid, hydroxymethylcellulose, hydroxyethylcellulose carboxymethylcellulose; and derivatives thereof; wherein the platelets in said platelet-rich plasma have been activated to release platelet growth factors by said activator, and wherein said biocompatible polymer is mixed with the activated platelets to form said platelet gel before the start of clot formation.
