Claims20
A container for mixing bone cement, comprising:
- a flexible bag member, said flexible bag member having a substantial vacuum formed therein;
- means, operably associated with said flexible bag member, for allowing transfer of a substantially liquid composition into said flexible bag member;
- and
- a powder polymer disposed within said flexible bag member for mixing with a liquid monomer to form a bone cement;
- wherein said liquid transfer allowing means comprises a port member which is disposed along an outer surface of said flexible bag member.

A method of preparing bone cement for securing articles to bones, comprising the steps of;
- obtaining a flexible container having a powder polymer therein, said flexible container being substantially vacuum sealed and having a substantial vacuum formed therein, said flexible container having a port member disposed along a surface thereof, said flexible container further comprising a membrane which extends across said port member, wherein said membrane has not been previously punctured;
- obtaining an instrument for holding and dispensing a liquid composition;
- placing a liquid monomer in said instrument;
- injecting said liquid monomer from said instrument into said flexible container by inserting a portion of said instrument through said port member of said flexible container;
- and
- mixing said liquid monomer with said powder polymer within said flexible container.
