Abstract

A variety of arrangements and methods relating to a defibrillator and a multiphasic pulse generator are described. In one aspect of the invention, a defibrillator includes two paddles that each include a defibrillator electrode covered in a protective housing. The two paddles are sealed together using a releasable seal to form a paddle module such that the housings of the paddles form the exterior of the paddle module. The multi-phasioc pulse generator includes a first subsystem, a second subsystem, and a switching component is electrically coupled with the paddles. The first subsystem and the second subsystem are arranged to generate a first phase of a pulse and a second phase of the pulse, the first phase of the pulse having a positive phase or a negative phase, and the second phase of the pulse having a phase in opposite polarity to the first phase of the pulse. The switching component switches between the first subsystem and the second subsystem to generate a therapeutic pulse having at least a positive phase and a negative phase.
