Abstract
A medical system and method can used to treat a bone. The system and method can include the preparation of bone cement to be used in the treatment. A non-liquid component and a liquid component can be combined to form a bone cement. A vacuum system can be used to saturate the non-liquid component with the liquid component. The bone cement and/or components can be heated and/or cooled.
Claims19
A system for preparing bone cement, comprising:
- a base configured to couple to one or more elongate members, at least one of the elongate members configured to hold a non-liquid polymer component in a lumen thereof and configured to receive a liquid monomer component therein for saturation of the non-liquid polymer component by the liquid monomer component to form a curable bone cement;
- and
- a negative pressure source configured for detachable communication with the base to draw the liquid monomer component into the non-liquid powder component;
- one or more valves for selectively coupling the negative pressure source to particular elongate members of the plurality of elongate members;
- a computer controller configured to control the plurality of valves, such that the valves can be opened or closed substantially simultaneously or a selected time intervals;
- wherein the computer controller comprises a signal system to indicate to a user when to use a particular elongate member in a particular medical treatment or when to add liquid monomer component to a particular elongate member, and
- wherein the base comprises one or more pathways that communicate with the lumen of the one or more elongate members and the negative pressure source.

A system for preparing bone cement, comprising:
- a structure for receiving a plurality of bone cement preparation members, wherein the plurality of bone cement preparation members are configured to receive a liquid monomer component and a non-liquid polymer component, the combination of which forms a curable bone cement within the plurality of bone cement preparation members, the structure comprising:
- a plurality of channels configured to connect an end of each of the plurality of bone cement preparation members to a negative pressure source;
- and
- a plurality of temperature regulating assemblies, each assembly configured for heating or cooling one of the plurality of bone cement preparation members;
- and
- a computer controller for controlling the amount of heat or cooling provided to the plurality of bone cement preparation members to heat or cool one of the components or the curable bone cement therein.
