    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: 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: A method and apparatus for assessing the risk of atrial fibrillation in a patient by calculating the relative frequency of short and long intervals between successive heart beats during sinus rhythm is presented. An imbalance of short over long sinus intervals has been found to indicate a higher risk of atrial fibrillation. An implantable cardiac device may be configured to automatically deliver interventional therapy to restore sinus interval balance when such an imbalance is detected.

    摘要: Methods and devices of cardiac electrode placement involve locating electrodes on a thorax of a patient. Surface pacing levels are determined relative to a pacing limit. Surface electrode locations are selected or rejected based on the level being within a limit. Electrodes may be relocated to new locations, and new surface pacing levels determined, until a new surface pacing level falls within the pacing limit. Selecting or rejecting electrode locations involves selecting locations suitable for implantation of subcutaneous cardiac electrodes and implanting at the selected locations. An automated method uses an array of surface electrode elements that are scanned for their associated pacing levels, such as by selecting one or more electrode element locations having the lowest pacing levels, which may correspond to locations suitable for implantation of a subcutaneous cardiac electrode and housing, a subcutaneous electrode array, a unitary subcutaneous defibrillation system, or other suitable implantable cardiac device.
