摘要： Apparatus and method according to the disclosure relate to promoting flow of body fluids in and around and between a substantially planar cardiac-sensing electrode and a shroud member utilizing spacing therebetween and/or one or more apertures, notches, slots and the like. For example, a relatively recessed area or aperture formed in an exemplary resin-based shroud member includes apertures that cooperate to promote flow of body fluids therearound.

摘要： Apparatus and method according to the disclosure relate to substantially planar cardiac-sensing electrodes and a shroud member utilizing protruding surface features such as one or more discrete and/or elongated projections, bumps, bosses and the like. For example, the exposed exterior surface of an electrode includes one or more protruding features that promote flow of body fluids therearound and potentially reduce tissue encapsulation.

摘要： Apparatus and method according to the disclosure relate to a mechanically and electrically coupling a plurality of electrodes to major opposing surface portions of an implantable medical device (IMD). The surface portions can comprise major opposing surfaces of a connector module of the IMD and/or substantially planar metallic surfaces of the IMD. The electrodes provide a subcutaneous cardiac activity sensing device via the plurality of electrodes which can be used in conjunction with one or more electrodes disposed in an insulative shroud coupled to the peripheral, minor surfaces of the IMD.

摘要： Improved implantable medical devices (IMDS) and more particularly, a subcutaneous multiple electrode sensing and recording system for acquiring far- and near-field electrocardiographic (ECG) data and waveform tracings. The far-field ECG data and/or waveform tracings is used to confirm or refute sensing and detection performed by the near-field (e.g., epicardial and/or intracardiac) electrodes which collect electrograms (or EGMs). Thus, subcutaneously implanted devices adapted to sense near- and far-field cardiac activity offer improved specificity and sensitivity in arrhythmia sensing and detection. The far-field ECG signals are collected via at least a pair of electrodes that are directly mechanically coupled to the housing for the IMD (and thus spaced from the myocardium) which are filtered and processed and used in addition to the near-field EGM signals collected by lead-based electrodes.

摘要： Apparatus and method according to the disclosure relate to a resilient shroud member mechanically and electrically coupled to an implantable medical device (IMD). The assembly is used to provide a subcutaneous cardiac activity sensing device via at least a pair of electrodes mechanically coupled to the shroud member. In the event that a patient needs to be notified for a follow-up visit to a clinic or the IMD requires attention, the electrode array signals the patient via a small electrical current passing through a surgical pocket.
