A magnetic-resonance-imaging-compatible (MRI-compatible) cardiac defibrillator includes: a defibrillator generator; first and second electric wires, each being electrically connected to said defibrillator generator; first and second defibrillation pads, each being electrically connected to a respective one of said first and second electric wires; and a low pass filter electrically connected between said defibrillator generator and said first and second electric wires to prevent a noise in an MRI image caused by a radiofrequency interference from the defibrillator as well as protect a patient and the defibrillator from MRI radiofrequency imaging signals, wherein said low pass filter has a cutoff frequency set such that differential mode noise at an MRI Larmor frequency is in an attenuated band while a system-test signal by said defibrillator generator is in a pass band of said low pass filter.

The present invention provides a method and device for non-invasive anatomical and systemic cooling, fluid removal and/or energy removal. The method and device provide for removal of fluid and cooling of various bodily fluid-containing spaces or surfaces, such as mucus-containing spaces or surfaces via delivery of a dry fluid not including a coolant into or upon the mucus-containing space or surface. Exposure of such mucus to the dry fluid results in evaporation of body fluid, removal of energy, cooling of the anatomical feature, and systemic cooling. In this fashion, therapeutic hypothermia may be achieved to provide for neuroprotection of various organs after ischemic insult, such the brain after cardiac arrest. Similarly, excess fluid removal may be achieved for treatment of cardiogenic shock or other conditions that cause significant fluid build-up, especially in cases of compromised renal function. Additionally, the invention may be used to reduce fever, and other conditions where removal of heat, energy and/or water are beneficial.

The present invention provides both methods and devices for termination of arrhythmias, such as ventricular or atrial tachyarrhythmias. The device and method involves application of alternating current (AC) for clinically significant durations at selected therapeutic frequencies through the cardiac tissue to a subject experiencing arrhythmia. Methods are also provided to minimize or eliminate pain during defibrillation.

MRI-compatible cardiac defibrillator

Methods and devices for treating patients having cardiopulmonary disease such as cardiac arrhythmias, ventricular arrhythmias, pulmonary hypertension, or heart failure comprising a tracheal approach. The method includes ablating a deep cardiac plexus of a patient by advancing an treatment apparatus into a trachea of the patient, extending an ablative energy delivery element of the treatment apparatus through a wall of the trachea at a level of the trachea proximate a tracheal bifurcation, positioning the ablative energy delivery element at a target space between the trachea, an aorta and a pulmonary artery, and ablating, by the ablative energy delivery element, tissue within the target space to substantially disable the deep cardiac plexus.
