1. A device, comprising:

  • a body portion including at least one first compartment and at least one second compartment, the at least one first compartment configured to hold at least one fluid composition, the body portion including at least one first port, wherein the at least one first port provides fluid communication between the at least one first compartment and the at least one second compartment, the at least one fluid composition including at least one first fluid and at least one agent;

    wherein the at least one first compartment includes cooling means for providing conditions for a time sufficient to solidify the at least one fluid composition into at least one frozen fluid composition;

    inlet means for facilitating introduction of at least one fluid composition into the body portion;

    one or more apertures configured to extrude at least one frozen fluid composition to at least one frozen particle composition or frozen piercing implement, wherein the one or more apertures are in fluid communication with the at least one first compartment and the at least one second compartment;

    wherein the at least one second compartment is configured to hold at least one frozen fluid composition, the body portion including at least one second port,wherein the at least one second port provides fluid communication between the at least one second compartment and an environment external to the body portion;

    pressure means for facilitating contact between the at least one frozen fluid composition and the one or more apertures, and movement of the at least one frozen particle composition or frozen piercing implement extruded from the one or more apertures into the at least one second compartment;

    the at least one second compartment having at least one second port, the at least one second compartment configured for holding at least one second fluid, and configured for receiving the at least one frozen particle composition or frozen piercing implement extruded from the one or more apertures; and

    expansion means for inducing a volume expansion of the at least one second fluid in the at least one second compartment to propel the at least one frozen particle composition or frozen piercing implement through the at least one second port to the external environment.
