Problems solved by technology

Today's implantable medical devices are also vastly more sophisticated and complex than their predecessors, and are therefore capable of performing considerably more complex tasks for reducing the effects of these health ailments.
The left ventricle is a portion of the heart that can be difficult in which to locate a lead due to the specific anatomical structure of the heart.
This procedure is difficult due to the tortuous path that the lead is subjected to and due to the reduced diameter of the cardiac veins in the more distal locations.
Another factor that complicates the left ventricular procedure is that the leads are limited in active fixation mechanisms.
These fixation methods may be difficult for use with left ventricular leads due to the specific anatomical structure of the left sided endovenous system.

Embodiment Construction

[0027] Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0028] Embodiments of the present invention concern an electrical lead that may be implanted and used to stimulate and / or sense the atrium and ventricle of the left side of the heart through the coronary sinus. As is well known, there has to date been a great difficulty in reli...

Abstract

Apparatus and methods are disclosed for inserting electrical leads within a heart. In one aspect of the present invention, a method for positioning a medical electrical lead in a cardiac vein is disclosed. The method comprises inserting a lead within a coronary sinus, dispersing at least one vasodilating agent to dilate at least one cardiac vein, and inserting the lead into a dilated cardiac vein.

Description

PRIOR APPLICATION [0001] This application is a continuation application of prior U.S. patent application Ser. No. 10 / 041,802, filed on Oct. 29, 2001 entitled “Method and Apparatus for Endovenous Pacing Lead”.FIELD OF THE INVENTION [0002] This invention relates generally to a method and apparatus for electrically stimulating a heart, and, more particularly, to a method and apparatus for positioning and fixating an electrode lead to stimulate and / or sense activity in the heart. DESCRIPTION OF THE RELATED ART [0003] Since their earliest inception some forty years ago, there has been a significant advancement in body-implantable electronic medical devices. Today, these implantable devices include therapeutic and diagnostic devices, such as pacemakers, cardioverters, defibrillators, neural stimulators, drug administering devices, among others for alleviating the adverse effects of various health ailments. Today's implantable medical devices are also vastly more sophisticated and complex ...
