Abstract
A monomer delivery device for a bone cement delivery system having a sealed body that has and a chamber sized to receive an ampule of monomer, a collar attached to the body having a blade configured to sever the ampule and a spout attached to the collar to expel the monomer.
Claims12
A monomer dispensing apparatus, comprising:
- a container having a chamber configured to receive a monomer ampule therein, said container defining an exit port though which monomer may advance;
- an ampule breaker located within said container;
- a valve configured to (i) inhibit advancement of monomer from said monomer ampule to said exit port when said valve is located in a closed valve position, and (ii) allow advancement of monomer from said monomer ampule to said exit port when said valve is located in an open valve position;
- and
- a first coupling attached to said valve, said first coupling being configured to couple to a second coupling of a mixing apparatus,
- wherein said container includes a spout which defines said exit port, and
- wherein said valve is attached to said spout.

A monomer dispensing apparatus, comprising:
- a container having a chamber configured to receive a monomer ampule therein;
- an ampule breaker operable to break said monomer ampule;
- a valve configured to receive monomer from said monomer ampule after breaking of said monomer ampule by said ampule breaker;
- and
- a first coupling attached to said valve, said first coupling being configured to couple to a second coupling of a mixing apparatus,
- wherein said valve is configured to inhibit advancement of monomer through said valve when said valve is positioned in a closed position.
3 more elements
A method of dispensing monomer, comprising the steps of:
- locating a monomer ampule within a container an exit port;
- breaking said monomer ampule within said container after said locating step;
- inhibiting advancement of monomer from said monomer ampule to said exit port with a valve after said breaking step;
- advancing monomer from said monomer ampule to said exit port through said valve after said inhibiting step;
- placing said exit port in fluid communication with a mixing apparatus;
- and
- advancing monomer from said monomer ampule to said mixing apparatus through said valve after said placing step.
