1. A defibrillator, comprising:
- two paddles for delivering a shock to a patient;
each paddle having a microneedle array with two or more rows of conductive microneedles;
a device for generating a therapeutic current to deliver the shock to the patient through the two paddles, wherein the device has at least a battery and a capacitor and is partially incorporated within the paddles; and
wherein the microneedle array of the two paddles applies a voltage and causes electroporation of a skin surface of the patient and delivers the shock to the patient through the skin surface.

14. A method for reducing patient transthoracic impedance for the purpose of delivering a therapeutic current, the method comprising:
-
providing a microneedle array having two or more rows of microneedles; performing electroporation of a skin surface of the patient by applying a voltage using the microneedle array; puncturing one or more layers of the skin surface using the microneedle array; and delivering a therapeutic current and a shock through the skin surface of the patient using the microneedle array at a reduced power due to a reduced transthoracic impedance caused by the electroporation and/or the microneedles. - View Dependent Claims (15)
