Patent ID: 7584005

Claim:
An implantable distal tip electrode comprising: an annular section defining an interior space and having a sidewall extending from a proximal end of the implantable distal tip electrode to a distal end of the implantable distal tip electrode, the sidewall having a wall thickness of less than 0.010 inches; a weld electrode extending between said proximal end and said distal end and defining said interior space between the weld electrode and the sidewall a medical compound disposed within the interior space; an outer surface of the sidewall defining a set of cut out regions, at least one of the cut out regions defining a conduit to provide fluid communication between the medical compound and an exterior environment to allow for elution of the medical compound into the exterior environment; the distal end of the implantable distal tip electrode defining a first port; and the proximal end of the implantable distal tip electrode defining a second port in communication with the first port through the interior space; wherein the implantable distal tip electrode is formed of a low resistance material.
