Abstract
A system is provided for the storage, preparation and administration of calcium phosphate cements. The subject invention provides a storage means for storing a two component calcium phosphate cement having a liquid component and a dry component. Also provided is a preparation means for combining the two components of the cement while present in the storage means. The subject invention further provides a means for administering the prepared cement to a physiological site. The subject devices and methods find use in a variety of applications where the introduction of a flowable material capable of setting to a solid calcium phosphate mineral to a physiological site is desired, including dental and orthopedic applications.
Claims19
A mixing device for mixing a two component cement present in a storage means comprising:
- (a) a first compartment comprising said liquid component;
- (b) a second compartment having rounded corners and comprising said dry component;
- (c) a first frangible barrier separating said first and second compartments;
- (d) a third elongate compartment capable of receiving a product produced upon combination of said dry and liquid components;
- and (e) a second frangible barrier separating said second and third compartments;
- said device comprising:
- a positioning means for holding said storage means in position;
- a means for moving said liquid component from said first compartment to said second compartment through said frangible seal;
- a means for thoroughly combining said liquid component with said dry component in said second compartment to produce a flowable product substantially free of uncombined dry and liquid components;
- and
- a means for moving said flowable product from said second compartment to said third compartment through said second frangible seal.
