Abstract
Abstract An intravenous lead for use with a cardiac device for implantation in the coronary sinus or the coronary sinus and great cardiac vein of the heart provides positive fixation for the lead when implanted in the coronary sinus or the coronary sinus and great vein of the heart. The lead includes a lead body adapted to be fed into the coronary sinus and great vein of the heart of a patient and at least one electrode carried by the lead body and adapted to be coupled to the implantable cardiac device. The lead body includes a preformed section having a resiliently coiled configuration. The coiled section is a left-handed turned coiled section which provides superior positive fixation of the lead as compared to right-handed turned coiled sections for use in the coronary sinus and great cardiac vein.

84 words
A method of implanting an intravenous cardiac lead within the coronary sinus or the coronary sinus and great vein of the human heart, said method comprising the steps of: providing a cardiac lead having a flexible lead body; feeding said lead body to a predetermined position within the coronary sinus or great vein of the heart; and imparting a left-handed turned coiled configuration to said lead body for making substantially continuous surface contact with inner wall surfaces of the coronary sinus or great vein.
Claim 8
Independent Claim
84 words
A method of implanting an intravenous cardiac lead within the coronary sinus or the coronary sinus and great vein of the human heart, said method comprising the steps of: providing a cardiac lead having a flexible lead body; feeding said lead body to a predetermined position within the coronary sinus or great vein of the heart; and imparting a left-handed turned coiled configuration to said lead body for making substantially continuous surface contact with inner wall surfaces of the coronary sinus or great vein.
Claim 9
Dependent Claim
122 words
