Abstract: In accordance with one embodiment, a leadless implantable medical device (LIMD), compromises a hermetic housing that has a distal portion and proximal portion. An electrode is proximate to the distal portion. An electronics package is disposed in the housing, in which the electronics package is configured to generate and deliver stimulation signals to the electrode. A fixation mechanism is disposed on the distal portion of the housing. A torque mechanism is disposed on the proximal portion of the housing. The torque mechanism has a tool engagement element movably coupled to the housing. The tool engagement element has a rotational force applied thereto during implant. The torque mechanism includes a torque limiter that maintains a fixed relation between the tool engagement element and the housing when in an engaged state. The torque limiter changes from the engaged state to a disengaged state when the rotational force exceeds a predetermined torque limit.

Abstract: An implantable therapy lead is disclosed herein. The therapy lead includes an integrated distal tip assembly with a header. At least one of a helix-shaft assembly, a ring electrode or a marker ring is directly coupled to the header via a snap-lock coupling arrangement.

Abstract: An implantable lead assembly includes an elongated body, a bobbin, and a conductor. The elongated body includes a distal end having an electrode and a proximal end having a header connector portion for coupling the elongated body with an implantable medical device. The bobbin is disposed in the elongated body. The conductor is disposed in the elongated body and is electrically coupled with the header connector portion and the electrode. The conductor is wound around the bobbin to form first and second inductive coils that are axially separated from each other by an inter-coil gap formed from the bobbin. The first and second inductive coils have different self resonant frequencies.

Abstract: An implantable therapy lead employs electrical conductors configured to enhance the abrasion resistance of the lead. Specifically, conductors are configured to create a surface contact area with walls of a wall lumen of a tubular body that is greater than would otherwise be possible with traditional conductors that have a circular transverse cross-section. As a result, the abrasion pressure of the conductors against the lumen walls is decreased for the conductors disclosed herein as compared to that of traditional conductors.
