Medicament Delivery Device

Abstract

The present disclosure relates to a medicament delivery devicecomprising at least one microneedle for delivering a medicament to a patient, and a system configured to enhance the penetration of the medicament into skin of the patient.

1 . A method comprising:
 applying a voltage differential to a first electrode of a medicament delivery device and a second electrode of the medicament delivery device to generate an electric field, and   flowing medicament from a reservoir to an array of microneedles arranged on the skin, wherein the electric field increases the flow of medicament.   
     
     
         2 . The method of  claim 1  further comprising:
 ionizing molecules of air present between the first and second electrode using the electric field, and 
 flowing the ionized molecules of air towards skin of a patient using the electric field, such that a permeability of the skin is increased. 
 
     
     
         3 . The method of  claim 1 , wherein applying a voltage differential to a first electrode of a medicament delivery device and a second electrode of the medicament delivery device to generate an electric field comprises applying a pulse to the voltage differential to generate a pulsing electric field. 
     
     
         4 . A method comprising:
 applying a heating element of a drug delivery device to skin of a patient thereby increasing a permeability of the skin, wherein the heating element is permeable, and   flowing a medicament through the heating element to the skin of the patient.   
     
     
         5 . The method of  claim 4 , wherein the heating element is disposed upstream of an absorbent pad or parallel to the absorbent pad.
