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.

28. An energy delivery device for delivering an energy pulse to a patient, said energy delivery device comprising:
-
an energy storage device; an energy discharge circuit comprising a plurality of delivery switches, said delivery switches being selectively operable to deliver to the patient energy from said energy storage device in a form of at least one energy pulse in a waveform, each of said delivery switches having an on condition and an off condition for enabling delivery of energy in different stages of said waveform; at least a first turn on circuit for a first switch of said plurality of delivery switches and a second turn on circuit for a second switch of said plurality of delivery switches; a controller that shifts at least said first switch of said plurality of delivery switches to an on condition and at least said second switch of said plurality of delivery switches to an off condition for generating a first waveform phase and shifts at least said second switch to an on condition and at least said first switch to an off condition for generating a second waveform phase; a first shoot-through elimination circuit that is operable to keep said first switch in an off condition when said second switch is shifted to an on condition by operation of said controller; and a second shoot-through elimination circuit that is operable to keep said second switch in an off condition when said first switch is shifted to an on condition by operation of said controller. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
