LEAD WITH ORIENTATION FEATURE
First Claim
1. A left ventricular lead for placement in a branch vessel of the coronary sinus, the vessel having a vessel wall and an adjacent myocardium, the lead comprising:
- a lead body having a lumen extending therethrough;
at least a first electrode on the lead body; and
at least a first orientation feature protruding from the lead body for orienting one or more of the electrodes into contact with the myocardium.

Abstract
A left ventricular lead is provided for placement in a branch vessel of the coronary sinus, the vessel having a vessel wall and an adjacent myocardium. The lead includes a lead body having a central lumen extending therethrough, at least a first electrode on the lead body and at least a first orientation feature protruding from the lead body for orienting one or more of the electrodes into contact with the myocardium. The lead may also include a pre-shaped curvature. The orientation feature may also aid in steering the lead into a selected branch vessel of the coronary sinus and in fixing the lead within the branch vessel.
