Patent ID: 8641661

Claim:
A system comprising: a cylinder having a bore with a piston disposed therein, the piston moveable along the bore of the cylinder and having a passage therethrough; a mixer disposed in the passage in the piston and including at least one porous mixing device, the at least one porous mixing device comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough, and having physical characteristics to sufficiently mix first and second components, which characteristics include a selected one or more of mean flow pore size, thickness and porosity; and a container attachable to the passage and moveable with the piston, wherein at least one of the bore and the mixer has a first component disposed therein and the container has a second component disposed therein, the second component transferred from the container to the bore through the passage in a first state, and a mixture of the first and second components transferred from the bore in a second state, and wherein the mixture of the first and second components is transferred from the bore to the container in a third state, and the mixture of first and second components is subsequently transferred from the container to the bore in a fourth state.
