摘要： A feedthrough filter capacitor assembly (10) and related installation method are provided for shielding a conductive terminal pin or lead (12) of the type used, for example, in an implantable medical device such as a heart pacemaker or defibrillator, against passage of external interference signals. The feedthrough assembly (10) includes a terminal pin subassembly (26) having at least one terminal pin (12) supported within a cylindrical conductive ferrule (28) by a hermetically sealed insulator ring (30). The ferrule (28) is adapted for mounting onto a conductive pacemaker housing (22), as by welding or brazing, to support the terminal pin (12) for feedthrough passage to the housing interior. A co-axial filter capacitor (24) is mounted at an inboard side of the pacemaker housing (22), with capacitor electrode plate sets (40,42) coupled respectively to the pacemaker housing (22) and to the terminal pin (12) by a conductive adhesive (54) or the like. In one preferred form, multiple filter capacitors are provided in a substantially coplanar array within a common base structure, with each capacitor in association with a respective terminal pin.

摘要： The capacitor comprises at least two conductive plates (12, 14) encased at a selected gap within a substantially monolithic casing (24) of selected dielectric material such as a ceramic material. The plates (12, 14) each include a tab (28, 30) projecting beyond an adjacnt margin of the adjoining plates. Recessed seats (20, 22) are formed in the casing as by drilling to bridge at least partially into the tabs (28, 30). Conductive lead ends (16, 18) are attached to the capacitor by soldering within the recessed seats, thereto securely anchoring the leads in a manner substantially impervious to moisture penetration.

摘要： An improved ceramic feedthrough capacitor design which results in distinct advantages in EMI (electromagnetic interference) filtering and therapeutic waveform management for implantable defibrillators and pacemakers and the like. The invention provides ceramic capacitor electrode plate designs which provide both low impedance decoupling for EMI suppression, and, at the same time provide an isolated common ground point through a separate coupling capacitor for electrical isolation of the filtered circuit from the metal case (usually titanium) of the defibrillator or the like. Such an arrangement allows the defibrillator HV (high voltage) output pulse to the heart to be referenced lead to lead (including reverse polarity), or from either lead to a common floating ground point or to the titanium case. The primary application of the invention is directed to implantable defibrillators where the output pulse to the heart is typically high voltage (up to 750 volts) and of short duration (typically in the 10 X 10 -3 seconds or 10 millisecond range). The invention is equally applicable to implantable pacemakers. The invention is particularly suited for a combination defibrillator (tachycardia) and pacemaker (bradycardia) unit where there are sense (heart monitoring), low voltage (pacing) and high voltage (defibrillator) output leads.
