Medical electrical lead
First Claim
1. A method of positioning an electrode within a coronary sinus/cardiac vein of a patient'"'"'s heart, comprising:
- advancing a lead having an elongated lead body carrying an active fixation device and having an electrode located on the lead body distal to the fixation device through a coronary ostium of the patient'"'"'s heart and into the coronary sinus/cardiac vein of the patients heart; and
employing the active fixation device to affix the lead to the patients heart outside of the coronary sinus/cardiac vein.

Abstract
A cardiac pacing lead and a method of its use. The lead has an elongated insulative lead body having a distal section formed into a curved configuration appropriate for use in a coronary sinus/cardiac vein of a patient'"'"'s heart. An active fixation device is located proximal to the distal, curved section of the lead body, which carries an electrode, located along the distal portion of the lead body, spaced from the active fixation device a distance appropriate to locate the electrode adjacent the left atrium or left ventricle of a human heart when the fixation device is located adjacent the ostium of the coronary sinus. The lead is used by advancing the distal portion of the lead through the coronary ostium of the patient'"'"'s heart and into the coronary sinus/cardiac vein and therefter employing the active fixation device to affix the lead to the patients heart outside of the coronary sinus/cardiac vein.

7. A cardiac pacing lead, comprising:
-
a first lead body component having an active fixation device located on a distal portion thereof and a second lead body component having a distal portion formed into a configuration appropriate for use in a coronary sinus/cardiac vein of a patient'"'"'s heart and slideably mounted relative to said first lead body component; a first electrode, located along said distal portion of said second lead body component, locatable adjacent the left atrium or left ventricle of a human heart when the fixation device is located adjacent the ostium of the coronary sinus of said human heart by sliding said first lead body component relative to said second lead body component; and an elongated conductor, extending through said second lead body component and coupled to said first electrode. - View Dependent Claims (8, 9, 10, 11)
