The ferrule passageway includes a proximal passage portion defined by one or more proximal sidewalls of the plurality of sidewalls and extending along the longitudinal axis, a distal passage portion defined by one or more distal sidewalls and extending along the longitudinal axis, and a beveled ledge disposed between the proximal passage portion and the distal passage portion and extending from the one or more distal sidewalls toward the longitudinal axis of the feedthrough ferrule. The beveled ledge includes a beveled surface extending toward the longitudinal axis, where a normal to the beveled surface intersects the longitudinal axis.
An example telemetry system includes telemetry circuitry configured to communicate with a first device and being located on a circuit board. The telemetry system includes a first bobbin, the first bobbin being located on a first side of the circuit board. The telemetry system includes a first coil, the first coil being wound on the first bobbin in a first direction. The telemetry system includes a second bobbin, the second bobbin being located on a second side of the circuit board. The telemetry system includes a second coil, the second coil being wound on a second bobbin in a second direction, the second direction being opposite the first direction. An outer loop of the first coil and an outer loop of the second coil are electrically coupled together.
A medical device is configured to deliver His-Purkinje pacing pulses according to multiple settings of a pacing control parameter and determine an electromechanical time delay from a ventricular electrical event to a fiducial point of the pressure signal for each of the pacing control parameter settings. The medical device may be configured to select an operating pacing control parameter from the pacing control parameter settings based on a determined electromechanical time delay being less than a threshold interval. The medical device may deliver pacing pulses to the His-Purkinje conduction system according to the selected operating pacing control parameter.
A61N 1/365 - Heart stimulators controlled by a physiological parameter, e.g. by heart potential
A61N 1/368 - Heart stimulators controlled by a physiological parameter, e.g. by heart potential comprising more than one electrode co-operating with different heart regions
