Systems and methods for fixating transvenously implanted medical devices
First Claim
1. A transvenously implantable medical device comprising:
- an electrical lead including an elongate lead body, the elongate lead body including an inner insulative sheath, an outer insulative sheath and a conductive layer disposed between the inner insulative sheath and the outer insulative sheath, the inner insulative sheath defining a lumen that is configured to accommodate a straightening member in order to adapt the electrical lead for transvenous implantation, the elongate lead body being pre-biased to expand from a collapsed state to an expanded state to mechanically engage an internal wall of a blood vessel upon removal of the straightening member;
a control module secured to and in electrical communication with the electrical lead, the control module including a signal management component and a power component disposed in a housing adapted for implantation into the blood vessel; and
a lumen extending through the control module to accommodate the straightening member.

Abstract
A transvenously implantable medical device (TIMD) includes an electrical lead and a control module. The electrical lead includes one or more electrodes and is adapted for transvenous implantation. The electrical lead is also pre-biased to expand from a collapsed state to an expanded state to mechanically engage an internal wall of a blood vessel. The control module is secured to and in electrical communication with the electrical lead. The control module includes a signal management component and a power component disposed in a housing adapted for implantation into the blood vessel. The control module is adapted for at least one of stimulating and sensing a physiologic response using the one or more electrodes of the electrical lead.
