Hemostatic powder delivery devices and methods of use

A device for delivering an agent, comprising:

• a valve assembly including a cavity and an agitation mechanism movably disposed inside the cavity;
• and
• a base including a magnetic mechanism movably disposed outside the cavity, wherein the magnetic mechanism is magnetically coupled to the agitation mechanism, and the base is configured to move relative to the valve assembly, thereby causing movement of the magnetic mechanism;
• wherein the agitation mechanism is configured to move within the cavity to agitate the agent stored therein in response to movement of the magnetic mechanism outside the cavity;
• and
• wherein the valve assembly is configured to mix the agent with a fluid received within the cavity and deliver a mixture of the agent and the fluid out of the cavity in response to movement of the agitation mechanism in the cavity.

A device for delivering an agent, comprising:

• a valve assembly including an outer enclosure, an inner enclosure including a cavity storing the agent, and an agitation mechanism, the inner enclosure is movably disposed inside the outer enclosure and the agitation mechanism is movably disposed inside the cavity;
• wherein the inner enclosure is magnetically coupled to the agitation mechanism, such that the inner enclosure is configured to move the agitation mechanism within the cavity in response to moving relative to the outer enclosure;
• and
• wherein the agitation mechanism is configured to agitate the agent stored inside the cavity in response to the inner enclosure moving within the outer enclosure.
