    Abstract: One aspect relates to a method for producing a ring electrode, including providing an outer element including an outer tube; providing a first inner element, including a first inner tube having a first core made of a sacrificial material, a material of the outer element and a material of the first inner element having a similar microstructure to each other; providing a second inner element, including a second core made of a sacrificial material; forming a composite tube by arranging the first inner element and the second inner element inside the outer element, the first inner element and the second inner element being arranged eccentrically; drawing the composite tube in a longitudinal direction of the composite tube, the material of the outer element and the material of the first inner element retaining a similar microstructure; separating a composite tube disk from the composite tube; removing the sacrificial material of the first core; and removing the sacrificial material of the second core to obtain a contacting opening in the ring electrode.

    Abstract: A system is provided that includes a first electrode configured to be located within a septal wall, and a second electrode configured to be located outside of the septal wall. The system also includes an impedance circuit configured to measure impedance along an impedance monitoring (IM) vector between the first and second electrodes. One or more processors are also provided that are configured to obtain impedance data indicative of an impedance along the IM vector with the first electrode located at different depths within the septal wall, the impedance data including a set of data values associated with different depths of the first electrode within the septal wall. The one or more processors are also configured to determine when the first electrode is located at a target depth within the septal wall based on the impedance data.

    Abstract: In various examples, a guidewire for temporary pacing of tissue includes an elongate core wire and a coil disposed along at least a portion of a length of the core wire. The coil is disposed radially outwardly from and around the core wire, wherein a core axis and a coil axis are substantially aligned. At least one electrode is disposed along the guidewire and includes an uninsulated portion of the core wire disposed within an electrode section of the coil. A spacing between adjacent windings of the electrode section of the coil is configured to allow a stimulation pulse to travel from the uninsulated portion of the core wire, through the spacing between the adjacent windings of the electrode section, and to the tissue in order to stimulate the tissue.
