The granted patent US12059573B2 describes a cardiac defibrillation system that includes a housing and an implantable lead with two ends. The lead features a defibrillation electrode and at least three detection electrodes, which are configured to form two distinct dipoles. The first dipole is defined by the first and second detection electrodes, with a length ranging from 5 to 50 millimeters, while the second dipole can be formed by various combinations of the detection electrodes and the housing, with a length between 50 and 400 millimeters. The patent also specifies that the system may include a controller for detecting electrical signals from both dipoles, with particular emphasis on detecting the R wave of the electrical signal.

Additionally, the implantable lead is designed with at least one fixing means to secure it to the patient's tissue, which can be positioned at various distances from the lead's ends. The patent outlines several configurations for the placement of the defibrillation electrode and detection electrodes, as well as the potential inclusion of an insulating sleeve covering the first dipole. The system may also incorporate sensors such as accelerometers or gyroscopes to monitor the patient's position. Overall, the claims detail a sophisticated design aimed at enhancing the functionality and effectiveness of cardiac defibrillation.
