  • Publication number: 20060293740
    Abstract: A cardiac pacing lead for electrically communicating with a human heart is attached to the heart using an adhesive. The lead includes a flexible, elongated lead body having a proximal end and a distal end, a pad having an interface surface coupled to the lead body at the distal end. An electrode is coupled to the pad. The lead further includes an adhesive for bonding the pad to the heart such that the electrode is electrically coupled to the heart. The adhesive is delivered to the interface surface after the lead has been inserted into a subject. In one embodiment, the lead system includes an anchor having an interface surface adapted for adhesive coupling to the heart. In this embodiment, the anchor is coupled to a tether and the lead includes a lumen adapted to accept the tether and to allow advancement of the lead over the tether.

  • Publication number: 20060155353
    Abstract: A spring fixation mechanism is adapted for fixing the distal end of an epicardial lead in a myocardium of the heart. The spring fixation mechanism is positioned at a distal end of the lead and includes a spring member and a stop. The spring member is formed about the lead and extends from a proximal end slidable relative to the lead to a distal end fixed to the lead. The stop is coupled to the proximal end of the spring member and is sized to be retained outside of an epicardium of the heart. The distal end of the lead, including the spring fixation mechanism, is inserted into the myocardium with a stylet and/or a pusher tube. The spring member is loaded and released, grasping tissue between adjacent coils of the spring member, fixing the lead within the myocardium.

  • Publication number: 20050149128
    Abstract: Various aspects of the present subject matter provide an implantable medical device. In various embodiments, the device comprises a pulse generator, a lead, a sensor, and a controller. The pulse generator generates a baroreflex stimulation signal as part of a baroreflex therapy. The lead is adapted to be electrically connected to the pulse generator and to be intravascularly fed into a heart. The lead includes an electrode to be positioned in or proximate to the heart to deliver the baroreflex signal to a baroreceptor region in or proximate to the heart. The sensor senses a physiological parameter regarding an efficacy of the baroreflex therapy and provides a signal indicative of the efficacy. The controller is connected to the pulse generator to control the baroreflex stimulation signal and to the sensor to receive the signal indicative of the efficacy of the baroreflex therapy. Other aspects are provided herein.
