Abstract
Various endocardial lead assemblies are disclosed that may be particularly useful for placement within the coronary sinus. One lead assembly includes an open-ended electrode that may be implanted in a patient by passing it along a previously implanted stylet. Another disclosed embodiment combines an open-ended electrode with one or more flow passages that improve blood flow through the body vessel in the area of the implanted electrode. Yet another disclosed embodiment uses an electrode that has flow passages but no opening. This electrode provides improved blood flow in the area of the electrode but may be implanted using conventional methods.
