Abstract: Methods and implantable medical devices are provided that include a lead configured to be operably coupled to a pulse generator and subcutaneously implanted within a patient. The lead includes an electrode configured to receive electrical power from the pulse generator and to deliver high-voltage shocks for defibrillation therapy. The electrode has an oblong cross-sectional shape with a major dimension that is at least 10 French (F).

Abstract: Systems and methods for implanting a lead. The system includes an active guidewire having proximal and distal ends. The distal end includes a guidewire anchor that is configured to be attached to a target SOL. The active guidewire is configured to be utilized to electrically map the target SOI by at least one of delivering stimulation energy through the active guide wire to the target SOI or sensing an evoked response at the target SOI from the guidewire. The system also includes a lead having a lead body with proximal and distal ends and with a lumen extending between the proximal and distal ends. The distal end of the lead body is configured to receive the proximal end of the active guidewire. The lumen is configured to permit the lead body to be advanced over the active guidewire.

Abstract: A device comprises external electrodes configured to be held proximate to a patient's skin and to sense conductive communication signals transmitted by an implantable medical device (IMD) within the patient. A dielectric layer is provided on at least a first electrode of the external electrodes to space the first electrode apart from the patient's skin to form a non-contact capacitively coupled interface between the patient's skin and the first electrode. The capacitively coupled interface is sensitive to the conductive communication signals. A circuit is connected to the external electrodes and is configured to output a differential signal corresponding to the conductive communication signals.

Abstract: Systems and methods for implanting a medical device include an implantable lead comprising a lead body having a distal end and a proximal end. The implantable lead has electrodes positioned at the distal end and has a lead connector positioned at the proximal end. The lead connector includes lead contacts that are communicatively coupled to the electrodes positioned at the distal end. The lead body has a body outer envelope configured to fit within a lumen of an introducer sheath and the lead connector has a connector outer envelope configured to fit within the lumen of the introducer sheath. A pulse generator has a connector cavity. The lead adaptor is configured to interconnect the implantable lead and the pulse generator. The lead adaptor has an insertable connector that includes mating contacts and an adaptor cavity that includes cavity contacts. The cavity contacts are positioned to engage the lead contacts of the lead connector when the lead connector is inserted into the adaptor cavity.
