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.
Claims12
A storage means for a two component calcium phosphate cement, said storage means comprising:
- a first compartment for housing a liquid component of said two component cement;
- a second compartment for housing a dry component of said two component cement, said second compartment comprising a means for selectively allowing the passage of gas out of said compartment;
- a first frangible barrier separating said first and second compartments;
- a third elongated compartment for receiving the product produced by combining the contents of said first and second compartments;
- and
- a second frangible barrier separating said third compartment from said second compartment.
A storage means comprising a two component calcium phosphate cement consisting of a dry component and a liquid component, said storage means comprising:
- a first compartment comprising said liquid component;
- a second compartment having rounded comers and comprising said dry component;
- a first frangible barrier separating said first and second compartments;
- a third elongate compartment capable of receiving a product produced upon combination of said dry and liquid components;
- and
- a second frangible barrier separating said second and third compartments.
