Abstract
A coronary sinus guiding introducer utilized to introduce medical devices, such as electrode leads, into the coronary sinus of a human heart. This guiding introducer contains a precurved distal portion, which curves through an arc of about 50 to 150 degrees. Preferably, the distal portion contains a pair of generally coplanar curves, wherein the arc of the first curve is from about 20 to about 60 degrees and the arc of the second curve is from about 30 to about 90 degrees and wherein the second curve is generally coplanar with the first curve. In an alternative embodiment, the second curve curves out of a plane formed by the first curve from about 15 to about 90 degrees. In addition, preferably the guiding introducer is splittable. Also disclosed is a process for introducing medical devices through the lumen of the precurved, coronary sinus guiding introducer.
