APPARATUS AND METHODS FOR MIXING MATERIALS
First Claim
1. A mixing apparatus comprising:
- a cylindrical body extending between proximal and distal ends with a hollow interior and an outlet at the distal end anda plunger including an elongated shaft with a distal end, a first mixing plate with a first plurality of holes extending therethrough, and a second mixing plate with a second plurality of holes extending therethrough,wherein the first and second mixing plates have a first relative position, adapted for mixing, in which the first and second plurality of holes are aligned and a second relative position, adapted for material dispensing, in which the first plurality of holes are blocked by the second mixing plate.

Abstract
A mixing apparatus comprises a cylindrical body extending between proximal and distal ends. The cylindrical body has a hollow interior and an outlet at the distal end. The mixing apparatus also includes a plunger having an elongated shaft with a distal end, a first mixing plate with a first plurality of holes extending therethrough, and a second mixing plate with a second plurality of holes extending therethrough. The first and second mixing plates have a first relative position, adapted for mixing, in which the first and second plurality of holes are aligned. The mixing plates have a second relative position, adapted for material dispensing, in which the first plurality of holes are blocked by the second mixing plate.

11. A method for mixing a medical composition comprising:
-
depositing first and second components of the medical composition into a cylindrical body having proximal and distal ends and a hollow interior; inserting a plunger into the hollow interior, wherein the plunger includes an elongated shaft with a distal end, a first mixing plate with a first plurality of holes extending therethrough, and a second mixing plate with a second plurality of holes extending therethrough; positioning the first plurality of holes in alignment with the second plurality of holes; and moving the plunger with an axial reciprocating motion within the cylindrical body to cause portions of the first and second components to move through the aligned first and second plurality of holes. - View Dependent Claims (12, 13, 14, 15)

17. A bone cement mixer comprising:
-
a syringe extending between proximal and distal ends, the syringe having a hollow interior and outlet at the distal end and a mixing mechanism sized for axial and rotational movement with the syringe, the mixing mechanism including a pair of mixing plates rotatable relative to each other to move between a first position in which a plurality of passages through the mixing plates are aligned to allow flowable bone cement components to pass through the pair of mixing plates and a second position in which the plurality of passages are misaligned to prevent flowable bone cement components from passing through the pair of mixing plates. - View Dependent Claims (18, 19, 20)
