1. A medical device for releasing a medicament, comprising:

  • a multi-layer patch, including;

    a base layer configured to secure the patch to a body of a user;

    a medicament array located adjacent the base layer, wherein the medicament array includes a plurality of wells each configured to contain and release a quantity of medicament from the medicament array to the body of the user;

    a bottom surface of each of the plurality of wells being configured to allow the quantity of medicament contained in each well to pass from the well to the body of the user in response to an increase in pressure against the well, and wherein the medicament array is configured to be elevated off of the body of the user when the patch is secured to the body of the user;

    a cover layer located on a side of the medicament array opposite the base layer;

    a pump operably coupled to the patch and configured to deliver a quantity of fluid to the patch;

    a controller operably coupled to the pump; and

    one or more sensors configured to measure one or more body parameters, wherein at least one body parameter is at least partially indicative of an effectiveness of the quantity of medicament, wherein the sensors are configured to relay information about the one or more body parameters to the controller, wherein at least one sensor is located on or proximate to the multi-layer patch, wherein at least one sensor comprises one or more electrodes and at least one body parameter comprises nerve conduction velocity, and wherein one or both the controller and pump comprise programming configured to receive input feedback from the one or more sensors, wherein the input feedback is used to adjust one or more dosage and delivery rate.
