Reconstitution device

An apparatus for reconstituting a medical substance comprising:

• (a) a body operable to hold a diluent, the body defining a longitudinal axis extending therethrough, wherein the body defines a first body diameter;
• (b) a first plunger configured to axially advance within the body, wherein the first plunger is configured to form a barrier within the body;
• and
• (c) a second plunger positioned within the body axially spaced from the first plunger, wherein the second plunger is configured to assume a first state and a second state, wherein the second plunger in the first state maintains an axially stationary position within the body, wherein the second plunger in the second state is operable to axially advance within the body, wherein the second plunger is operable to be activated to switch from the first state to the second state.

An apparatus comprising:

• (a) a cartridge body operable to hold a diluent;
• (b) an occlusion positioned longitudinally through the cartridge body;
• and
• (b) a first plunger in communication with the cartridge body, wherein the first plunger defines an opening configured to receive the occlusion, wherein the first plunger is frictionally held within the cartridge body, wherein the first plunger is movable between first state and a second state, wherein the first plunger in the first state fluidly blocks a portion of the cartridge body, wherein the first plunger in the second state allows at least a portion of fluid to flow through the opening of the first plunger.
