1. A permanently implantable intravenous lead capable of pacing the heart, comprising:

  • a permanently implantable elongated, flexible body member made of an electrically insulative material, said body member having a proximal end portion and a distal end portion;

    a lumen extending through the body member from the proximal end portion to the distal end portion of the body member;

    a conductive member extending through the body member from the proximal end portion toward the distal end portion; and

    a sealing assembly located at a distal end portion of the lead, the sealing assembly including a seal coupling element having a proximal portion, a distal portion, and a passage coaxial with the lumen and extending through the seal coupling element, the passage and lumen configured to allow for implantation of the lead over a guidewire, and the distal portion of the seal coupling element having a maximum outer diameter greater than a maximum outer diameter of the proximal portion, and a sealing element coupled to the seal coupling element and including a material that expands upon contact with bodily fluid to limit bodily fluid from entering the lumen.
