Abstract: Implantation of a cardiac stimulus system using the ITV. Access to the ITV may be performed using the intercostal vein as an access point, and entering the ITV through an ostium therebetween. The intercostal vein may be located on a costal groove on an inferior portion of a rib. Advancement from the intercostal vein to the ITV may then be performed in a superior direction, an inferior direction, or both.

Abstract: Implantation of a cardiac stimulus system using the intercostal veins. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed by entering the brachiocephalic vein from a jugular, subclavian, or other vein, and then accessing the internal thoracic vein, traversing a portion of the internal thoracic vein and then accessing an intercostal vein therefrom. Inferior access may be accomplished inferior to the lower rib margin via the superior epigastric vein, advancing superiorly into the internal thoracic vein and then accessing an intercostal vein therefrom. Intercostal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance to enter the intercostal vein directly.

Abstract: Implantation of a cardiac stimulus system using the ITV. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed using the brachiocephalic vein to access the ITV, with access to the brachiocephalic vein achieved using subclavian vein, using standard visualization techniques. A positioning mechanism may be advanced to the ITV, a location of the positioning mechanism may then be obtained, and an external access may then be established. Inferior external access may be accomplished inferior to the lower rib margin via the superior epigastric or musculophrenic vein. Intercostal external access may be accomplished via an intercostal vein between two ribs. A lead may then be attached to the positioning mechanism and drawn into the ITV.

Abstract: Implantable leads of a cardiac stimulus system are disclosed, as well as methods for implanting leads of a cardiac stimulus system. The lead may be comprised of a proximal portion having a coupler for coupling to an implantable pulse generator, an intermediate portion comprising a plurality of electrodes disposed thereon, and a distal portion. The intermediate portion may have a first diameter and the distal portion may have a second diameter. The distal portion may also have an attachment feature for attaching to a lead pulling tool for delivery to an ITV and an intercostal vein. Methods may include pulling a lead from a first position to a second position within the vasculature, exiting the vasculature at the second location, and attaching a portion of the lead that exits the vasculature to an electrode or implantable device for use with the lead.
