    Abstract: Described are selectable notch filter circuits comprising at least two different notch filter capabilities, each of which is capable of filtering interference of a designated fundamental frequency and a second harmonic of the designated fundamental frequency from an electrical signal. Each of the notch filters of the circuit is specific for real time filtering of a different designated fundamental frequency and a second harmonic thereof from digitized signal data input into the circuit. The filtering capability of each filter is dictated by control logic, which uses a coefficient set specific for the designated fundamental frequency and harmonics thereof. By using different coefficient sets, different designated fundamental frequencies and at least their second harmonic frequencies can be filtered from digitized signal data input into the circuit. Because the control logic can utilize at a given time any one (or, if desired, none) of the coefficient sets available to it, different interfering fundamental frequencies can be filtered, if and as necessary, from digitized input signal data collected over time at a substantially equivalent sampling rate. Also described are devices including one or more such selectable notch filter circuits, including implantable medical devices such as implantable cardioverter/defibrillators, as well as methods of using such devices.

    Abstract: A subcutaneous cardiac device includes two electrodes and a stimulator that generates a pulse to the electrodes. The electrodes are implanted between the skin and the rib cage of the patient and are adapted to generate an electric field corresponding to the pulse, the electric field having a substantially uniform voltage gradient as it passes through the heart. The shapes, sizes, positions and structures of the electrodes are selected to optimize the voltage gradient of the electric field, and to minimize the energy dissipated by the electric field outside the heart. More specifically, the electrodes have contact surfaces that contact the patient tissues, said contact surfaces having a total contact area of less than 100 cm2. In one embodiment, one or both electrodes are physically separated from the stimulator. In another embodiment, a unitary housing holds the both electrodes and the stimulator. Sensor circuitry may also include in the stimulator for detecting intrinsic cardiac activity through the same electrodes.

    Abstract: The invention relates to leadless cardiac pacemakers (LBS), and elements and methods by which they affix to the heart. The invention relates particularly to a secondary fixation of leadless pacemakers which also include a primary fixation. Secondary fixation elements for LBS's may either actively engage an attachment site, or more passively engage structures within a heart chamber. Active secondary fixation elements include a tether extending from the LBS to an anchor at another site. Such sites may be either intracardial or extracardial, as on a vein through which the LBS was conveyed to the heart, the internal or external surface thereof. Passive secondary fixation elements entangle within intraventricular structure such as trabeculae carneae, thereby contributing to fixation of the LBS at the implant site.

    Abstract: A comparator is arranged to compare a series of analog voltage signal samples on a first capacitor with a voltage on a second capacitor which is linearly increased or decreased to equal the sample value. The comparator's single output freezes the count of the counter at counts which are proportional to the voltage of the respective samples. In this manner, analog to digital conversion can be accomplished using a single line between the analog and digital sides of a circuit, thereby reducing parasitic capacitance.

    Abstract: A defibrillator output circuit utilizes an optically coupled signal for controlling an isolated electronic switch. Variants of the output circuit include coupling via phototransistors or photodiodes for the control of at least one electronic switch. An H-bridge circuit configuration with four switches is connected to a single energy storage capacitor for generating multiphasic shocks across a load. The polarity of the shocks is selectable. Optical coupling methods are employed for driving the high side switches in the H-bridge.
