Energy delivery apparatus and method
First Claim
1. An energy delivery storage device comprising:
- an energy storage device;
a controller;
at least two switches which are controlled by the controller and coupled to said energy storage device; and
an energy discharge circuit operably coupled to said energy storage device, said energy discharge circuit being selectively operable to deliver energy from said energy storage device to a patient via said at least two switches;
wherein one of said at least two switches also acts as a disarm circuit that prevents energy from being delivered to said patient when said disarm circuit is activated by said controller, andupon activation, the energy stored by said energy storage device is discharged and the energy storage device is electrically disconnected from the discharge circuit.

Abstract
There is provided an energy delivery device comprising a storage device, a discharge circuit and a disarm circuit. The discharge circuit comprises a switch electrically connected to the storage device, and is selectively operable to deliver energy from the storage device to a load, e.g., a patient needing defibrillation, preferably in a multiphasic waveform. The disarm circuit comprises the switch. Preferably, the discharge circuit comprises an H-bridge circuit. There are also provided delivery devices: which comprise a shoot-through elimination circuit; which include housing elements which, when assembled, cause electrical connection between respective components; which include a housing having a small volume and an energy storage device having a large capacitance; which comprise a shunt circuit which, when activated, prevents switching of a switch. There are also provided methods of assembly and disassembly of an energy delivery unit and methods of delivering energy to a load.
