    摘要: A medical device lead is presented that includes an electrode assembly having a first electrode located near a distal end of the electrode assembly and a second electrode located near a proximal end of the electrode assembly. The electrode assembly also includes a conductive elongated coupler that is electrically coupled to the first electrode and capacitively coupled to the second electrode. At low frequencies and DC (e.g., during delivery of stimulation therapy), the capacitive coupling between the conductive elongated coupler and the second electrode presents a high impedance allowing little current to be redirected from the first electrode to the second electrode. However, at high frequencies (e.g., during an MRI scan) the capacitive coupling between the conductive elongated coupler and the second electrode presents a low impedance, resulting in a significant amount of induced current being redirected to the second electrode and dissipated into bodily fluid surrounding the second electrode.

    摘要: A method of placing an electrical lead of an implantable cardiac device inside a heart of a patient. The method includes securing a tool to an atrial appendage of the heart to hold onto the atrial appendage, piercing the atrial appendage, and creating an aperture in the atrial appendage while holding the atrial appendage with the tool. The method also includes moving a distal end of the electrical lead into the heart through the aperture in the atrial appendage and into a ventricle of the heart. Furthermore, the method includes coupling the distal end of the electrical lead to cardiac tissue in the ventricle and delivering an electrical signal to the cardiac tissue in the ventricle of the heart to maintain a predetermined heartbeat of the heart.
