Abstract: An implantable biostimulator has a housing, one or more fixation elements at a distal end of the housing, and one or more electrode probes. The housing includes an electronics compartment containing pacing circuitry. The one or more electrode probes are coupled to the pacing circuitry. The one or more electrode probes are extendable from the distal end of the housing. The one or more electrode probes have depth control to a controlled depth of extension.

Abstract: A lead for an implantable medical device (IMD) includes an electrode having a plurality of brick segments that are discrete and mechanically connected to one another in a line. The brick segments are electrically conductive and electrically connected to one another. The brick segments are configured to be powered by a pulse generator of the IMD to deliver high-voltage shocks for defibrillation therapy.

Abstract: A biostimulator includes a housing having a longitudinal axis and containing an electronics compartment. A pacing element is coupled to the housing. The pacing element includes a flexible conductor extending along the longitudinal axis. A fixation element mount is mounted on the housing. The fixation element mount includes a distal mount end. A fixation element is mounted on the fixation element mount. The fixation element extends about the longitudinal axis. A radiopaque marker has a distal marker end longitudinally aligned with the distal mount end of the fixation element mount. Other embodiments are also described and claimed.

Abstract: A biostimulator includes a housing having a longitudinal axis and containing an electronics compartment. The biostimulator includes a fixation element coupled to the housing. The fixation element extends about the longitudinal axis. The biostimulator includes a pacing element coupled to the housing. The pacing element includes a flexible conductor extending along the longitudinal axis and a stiffening strand extending beside the flexible conductor. A bending stiffness of the stiffening strand is greater than a bending stiffness of the flexible conductor. Other embodiments are also described and claimed.

Abstract: Shocking electrodes for implantable medical devices may include a coiled conductor that has an oblong cross-sectional shape and is configured to deliver high-voltage shocks for defibrillation therapy. The coiled conductor includes an electrically conductive element that is helically wrapped and defines the oblong cross-sectional shape. The electrically conductive element is one of (i) a multi-filar ribbon wire that includes multiple strands disposed side-by-side along a length of the multi-filar ribbon wire, (ii) a micro-coil that includes a coiled strand, or (iii) a micro-cable that includes multiple interwoven strands along a length of the micro-cable.
