    摘要: An endocardial lead comprising an elongate body having a first defibrillation coil electrode, a second defibrillation coil electrode and a first pacing/sensing electrode. The first defibrillation coil electrode has a first end and a second end, where the first end is at or near the distal end of the elongate body and the second end spaced longitudinally from the distal end. The first pacing/sensing electrode is spaced longitudinally along the peripheral surface from the second end of the first defibrillation coil electrode. The second defibrillation coil electrode is spaced longitudinally along the peripheral surface from the first pacing/sensing electrode to afford positioning the first defibrillation coil longitudinally adjacent an apical location of the right ventricle of a heart with the first pacing/sensing electrode within the right ventricle of the heart and the second defibrillation coil within the right atrial chamber or a major vein leading to the right atrial chamber of the heart. The elongate body further includes a curved portion on which the first pacing/sensing electrode is positioned such that the first pacing/sensing electrode extends beyond the peripheral surface of the elongate body to engage the tissue of the heart. The first pacing/sensing electrode further includes a retaining element, where the retaining element is adapted to be embedded in the right ventricle of the heart to secure the first pacing/sensing electrode and the elongate body of the endocardial lead to the right ventricle of the heart.

    摘要: An intravenous lead for use with a cardiac device for implantation in the coronary venous system of the heart includes a lead body that is adapted to be routed through the vascular system into the coronary sinus with the distal end portion of the lead placed in the great cardiac vein or branch vein. The lead body includes a fixation member disposed just proximal of its tip. The fixation member comprises a radially expandable polymeric matrix that incorporates an osmotic agent so that when placed in a aqueous medium it will swell. Thus, when placed in a cardiac vein, the swelling of the fixation member will anchor the lead against longitudinal displacement due to body motion, blood flow and the beating action of the heart.

    摘要: An implantable defibrillation electrode including a conductive distal end portion and a non-conductive proximal end portion is provided with at least a major portion of the length of the distal end portion having a preconfigured shape and being resiliently deformable into a generally straight condition. The distal end portion includes distal and proximal ends and at least one of those ends is hollow and has hook structure shiftably supported therein for movement longitudinally thereof from a retracted position at least substantially contained within the hollow end and an extended position at least substantially fully outwardly projected from the hollow end. Spring structure is provided for yieldingly biasing the hook structure from the extended position toward the retracted position and axial thrust developing structure is slidingly telescoped through the proximal end portion and operatively associated with the hook structure for exerting an axial thrust thereon from the terminal end of the proximal end portion in order to effect shifting of the hook structure from the retracted position to the extended position.

    摘要: An implantable lead having a distal assembly including a coupler, a fixation helix secured to the coupler, a housing in which the fixation helix and the coupler are disposed, and a resilient seal that is fixedly secured to the coupler between proximal and distal ends thereof and able to translate with the coupler relative to the housing. The seal is positioned to sealingly engage an internal surface of the housing. When the coupler is translated such that the fixation helix is in a fully extended position, the seal is positioned to substantially seal off the housing to prevent tissue ingrowth.
