Shield for implantable cardioverter defibrillator

摘要: An implantable cardioverter defibrillator capable of subcutaneous positioning within a patient delivers at least one electrical cardioversion/defibrillation countershocks to the heart patient. The includes housing, circuitry positioned housing control delivery countershocks, and an energy source coupled with provide capacitor in that stores for countershocks. Because is susceptible undesirable electromagnetic coupling effects origin external circuitry, particularly capacitive between device when portion utilized as electrode, also conductive shield, disposed shield against such undesired effects.
