Enclosed implantable material mixing system

Abstract

An enclosed implantable material mixing system is described herein. The system uses an enclosable vial or container into which bone cement mixture may be mixed by agitation. The bone cement mixture may be made of a combination of polymer and liquid monomer, but because of the method of agitation, e.g., shaking the vial and its contents, the ratio of the monomer-to-polymer is critical. A desirable weight ratio of the monomer-to-polymer is about 0.3 to about 1, and more preferably about 0.53 to about 0.63, and is more preferably about 0.57. The vial or container may also include a free-floating, or disassociated, agitator to aid with the mixing process. To prepare the composition, the vial and its contents may be capped and shaken until the mixture dissolves completely. The contents of the vial are then allowed to sit and undergo a solvation process at the end of which the mixture may be shaken again and then poured out for use.
