A capacitive filtered feedthrough assembly is formed in a solid state manner to employ highly miniaturized conductive paths each filtered by a discoid capacitive filter embedded in a capacitive filter array. A non-conductive, co-fired metal-ceramic substrate is formed from multiple layers that supports one or a plurality of substrate conductive paths and it is brazed to a conductive ferrule, adapted to be welded to a case, using a conductive, corrosion resistant braze material. The metal-ceramic substrate is attached to an internally disposed capacitive filter array that encloses one or a plurality of capacitive filter capacitor active electrodes each coupled to a filter array conductive path and at least one capacitor ground electrode. Each capacitive filter array conductive path is joined with a metal-ceramic conductive path to form a feedthrough conductive path. Bonding pads are attached to the internally disposed ends of each feedthrough conductive path, and corrosion resistant, conductive buttons are attached to and seal the externally disposed ends of each feedthrough conductive path.

Structures and methods relating to electrodes for incorporation into a feedthrough with a profile adapted for subcutaneous sensing of physiologic and cardiac signals. Electrode assemblies are adapted for integration with feedthrough to enable maximal electrode spacing, minimal myopotential electrical noise and provide reliable insulation from the IMD housing. Various structures and manufacturing processes are implemented to provide a large sensing surface with a low profile. The subcutaneous sensing electrode assembly provides a leadless sensing system and further enhances installation and follow-up procedures.

The invention discloses a subcutaneous electrode array or SEA for use in medical devices. The arrangement provides an enhanced capability for detecting and gathering electrical cardiac signals via the array of relatively closely spaced subcutaneous electrodes. Further, switching circuits, signal processors and memory to process electric cardiac signals are implemented to enable a leadless orientation-insensitive SEA scheme for receiving the electrical signal from the heart. The SEA is distributed over the perimeter of the implanted medical device and includes a non-conductive surround shroud of biocompatible material. The surround shroud is placed around the periphery of the case of the implanted medical device. Various configurations of recesses, each of which contain individual electrodes, are implemented to provide an enhanced signal to noise ratio for improved signal quality.

Medical devices include stimulation and/or sensing circuitry that is interconnected to electrical components by a flexible circuit body having exposed portions of circuit traces that are attached to electrical contacts of the electrical components. Each circuit trace may span a separate window formed in an insulative body of the flexible circuit body, or a plurality of circuit traces may span a single window or may be freely extending from the insulative body. The exposed portion of the circuit trace may be plated with a conductive metal and then attached to the electrical contact of the electrical component. The flexible circuit body may be an extension from a flexible electrical circuit board containing the circuit. The circuit may be present on a circuit board that includes electrical contacts and where the flexible circuit body has exposed portions of circuit traces attached to the electrical contacts of the circuit board.

A combined venous and cardiotomy blood reservoir is provided that includes a rigid shell having a top, a bottom, and a continuous side wall. The top and bottom walls are connected to the continuous side walls so as to define a reservoir for venous and cardiotomy blood. A double column structure is provided within the blood reservoir, the first column for receiving and degassing venous blood, the second for receiving, filtering and defoaming cardiotomy blood. The venous blood filtering and defoaming components can include a top venous screen plate, a bottom venous screen plate or stand and a perforated venous cage captured therebetween. The venous column is of generally D-shape and has a double screen structure including an inner microscreen and an outer microscreen received respectively on the inside and outside of the perforated venous cage. The cardiotomy blood filtering and defoaming components can include an inner, first defoaming element, a core support frame, a depth filter, an outer, second defoaming element, and a filter covering sock.
