    摘要: Implantable subcutaneous devices and methods employ a lead and/or electrode for cardiac monitoring and/or intervention. The devices and methods may employ one or more fixation elements including, for example, tines, tines with barbs, spring-loaded tines, flexible or collapsible tines, and other tined fixation mechanisms configured to passively secure one or both of the electrode or body of the lead in subcutaneous non-intrathoracic tissue. A method of implanting subcutaneous leads according to the present invention involves providing a lead comprising a lead body, an electrode, and one or more fixation elements, and passively securing one or both of the lead body and the electrode to subcutaneous non-intrathoracic tissue at one or more fixation sites using the fixation elements. The method may involve use of a delivery device, such as a sheath, for lead delivery to a subcutaneous non-intrathoracic implant site.

    摘要: An implantable subcutaneous device and method employ a lead and an electrode for cardiac monitoring and intervention. The device includes an implantable lead having a lead body, a subcutaneous electrode coupled to the lead body, and a pharmacological agent provided on the implantable lead and/or electrode. The pharmacological agent provides a temporary therapeutic treatment to subcutaneous non-intrathoracic tissue. A method of implanting subcutaneous leads involves providing a lead including a lead body, a subcutaneous electrode, and a pharmacological agent, and delivering the pharmacological agent to subcutaneous non-intrathoracic tissue surrounding the lead.

    摘要: Cardiac monitoring and/or stimulation methods and systems provide monitoring, defibrillation and/or pacing therapies. A signal processor receives a plurality of composite signals associated with a plurality of sources, separates a signal using a source separation algorithm, and identifies a cardiac signal using a selected vector. The signal processor may iteratively separate signals from the plurality of composite signals until the cardiac signal is identified. The selected vector may be updated if desired or necessary. A method of signal separation involves detecting a plurality of composite signals at a plurality of locations, separating a signal using source separation, and selecting a vector that provides a cardiac signal. The separation may include a principal component analysis and/or an independent component analysis. Vectors may be selected and updated based on changes of position and/or orientation of implanted components and changes in patient parameters such as patient condition, cardiac signal-to-noise ratio, and disease progression.
