A system for delivering a medical electrical lead within a coronary venous system that includes an introducer kit for establishing venous access to the coronary venous system and a plurality of delivery sheaths, each corresponding to a desired approach to a coronary sinus of the coronary venous system and insertable within the coronary venous system through the navigation pathway. A hemostasis valve is coupled to a delivery sheath of the plurality of delivery sheaths, and a guide wire is inserted within the lead lumen, guiding delivery of the distal tip of the medical electrical lead to a target site within the coronary venous system through the hemostasis valve and the delivery sheath. Subsequent to the distal tip being delivered to the target sight, the hemostasis valve is advanced over the connector of the medical electrical lead to remove the hemostasis valve from the medical electrical lead.

Method and system for delivery of a medical electrical lead within a venous system

A loading device for loading a guide wire within a medical electrical lead that includes a navigation portion, having an outer portion, and extending from a front end to a back end, and having an opening formed at the back end. An engagement cavity receives and properly orientates the lead distal tip to align the lumen of the lead with the opening of the navigation portion during the loading of the guide wire within the lead. A first side wall is spaced from a second side wall to form a slot extending along the outer portion from the front end to the back end of the navigation portion, and the guide wire is advanced through the slot as the lead having the guide wire loaded therein is removed from the loading device.
