Abstract: A rechargeable cell of an implantable medical device is recharged by an external charging unit that includes a transmitting coil configured to emit an electromagnetic field and a near-field focusing plate having a subwavelength structure pattern that focuses the emitted electromagnetic field to a focal pattern. The implantable medical device includes a housing having a window of an electromagnetically transparent material and a receiving coil enclosed by the housing. The receiving coil extends adjacent to and is aligned with the window. The rechargeable cell is enclosed by the housing and is configured to be charged by current induced in the receiving coil when the receiving coil is exposed to the focal pattern. In some examples, the near-field focusing plate is configured to produce the focal pattern to have a size that is less than an outer dimension of the window and a focal length from the near-field focusing plate that at least reaches the window.

Abstract: This disclosure provides an extravascular ICD system and method for defibrillating a heart of a patient. The extravascular ICD system includes multiple extravascular electrical stimulation leads or lead segments located in close proximity to one another and having respective defibrillation electrodes. The ICD system utilizes the multiple defibrillation electrodes to form an extravascular electrode vector that may result a reduction in the shock impedance and/or a reduction in the DFT compared to extravascular ICD systems that include only a single extravascular defibrillation electrode. An ICD of the system may, for example, deliver a defibrillation shock using an electrode vector in which a first polarity of the electrode vector is formed by electrically coupling first and second defibrillation electrodes of first and second leads, respectively, to the therapy circuitry and a second polarity of the electrode vector is formed by electrically coupling a housing of the ICD to the therapy circuitry.
