Abstract
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.
