1. An implantable cardiac lead for connection to an implantable pacemaker or defibrillator comprising:
- (a) an elongated, flexible body member made of an electrically insulative material, said body member having a proximal end and a distal end;
(b) a conductive member extending through said body member from said proximal end toward said distal end;
(c) a contrast agent;
(d) a lumen extending alongside said conductive member through said body member from the region of said proximal end toward said distal end, said lumen having a first opening proximate said proximal end and a second opening through said body member distal of said first opening so that said contrast agent can be injected through said lumen and out of said second opening; and
(e) an electrode positioned on said flexible body member and electrically coupled to said conductive member.

17. A medical device system comprising:
-
(a) an implantable pulse generator;
(b) an implantable cardiac stimulation lead having an elongated, flexible body member made of an electrically insulative material, said body member having a proximal end and a distal end;
a conductive member extending through said body member from said proximal end toward said distal end;
a lumen extending alongside said conductive member through said body member from said proximal end toward said distal end, said lumen having a first opening through said proximal end and a second opening through said body member distal of said first opening so that a contrast agent can be injected through said lumen and out of said second opening; and
an electrode electrically coupled to said conductive member; and
(c) a contrast agent for delivery through said lead. - View Dependent Claims (18, 19)

20. A method for implanting an intravenous lead comprising the steps of:
-
(a) inserting said lead through a vein;
(b) guiding said lead through the right atrium and proximate the CS;
(c) delivering a bolus of contrast agent through a lumen of said lead and observing a dispersion pattern of said contrast agent; and
(d) using said dispersion pattern to determine a direction to move said lead. - View Dependent Claims (21, 22, 23, 24, 25, 26)
