US 2010/0137965 A1 · Coronary sinus lead for pacing the left atrium

Abstract

A method of inserting a pacing lead having a preformed shape into a coronary sinus to pace the left atrium includes providing a lead having an elongated body and proximal and tip sections. The sections are configured such that a first angle less than 90 degrees is defined between the lead body and proximal section and a second angle is defined between the tip and proximal sections. The method further comprises advancing the pacing wire towards the opening of the coronary sinus and advancing the wire into the coronary sinus, such that the first angle is compressed by the coronary sinus opening and a tip electrode included on the tip section contacts the wall of the coronary sinus near the left atrium operably extending the second angle to assure constant contact between the wall of the coronary sinus and the tip electrode.

Dependent claims

A pacing lead configured for implantation in a coronary sinus having an opening and a wall defining an interior, the pacing lead comprising:

a substantially straight elongated lead body having a first bend defined at a distal end thereof;
a proximal section having a second bend defined thereon, the proximal section extending from the first bend and defined between the first and second bends, such that a first inside angle less than 90 degrees is defined between the lead body and proximal section;
a tip section having a tip electrode disposed thereon, the tip section extending from the second bend, such that a second inside angle is defined between the tip and proximal sections, wherein the pacing lead is configured such that when at least a portion of the first bend is inserted into the opening of the coronary sinus, the first inside angle is operably compressed by the coronary sinus opening and the pacing lead folds over and the tip electrode contacts the wall of the coronary sinus adjacent to the lead body thereby operably extending the second angle.
