Abstract

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.
