Method and system for delivery of a medical electrical lead within a venous system
First Claim
1. A method of delivering a medical electrical lead within a coronary venous system, comprising the steps of:
- establishing venous access to the coronary venous system using an introducer tool kit;
choosing a delivery sheath from a plurality of delivery sheaths corresponding to a desired approach to a coronary sinus of the coronary venous system;
coupling a hemostasis valve over a proximal portion of the delivery sheath;
positioning the delivery sheath within the venous access;
inserting a guide wire within a lead lumen at a distal tip of the medical electrical lead;
inserting the distal tip of the medical electrical lead through the hemostasis valve and within the delivery sheath;
guiding advancement of the distal tip of the medical electrical lead to a target site within the coronary venous system using the guide wire; and
decoupling the hemostasis valve from the delivery sheath and advancing the hemostasis valve over a connector of the medical electrical lead to remove the hemostasis valve from the medical electrical lead.

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.

11. A system for delivering a medical electrical lead within a coronary venous system, the medical electrical lead extending from a connector to a distal tip and having a lead lumen located at the distal tip, the system comprising:
-
an introducer kit establishing venous access to the coronary venous system;
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;
an anchoring sleeve positioned along the medical electrical lead;
a hemostasis valve coupled to a delivery sheath of the plurality of delivery sheaths; and
a guide wire insertable within the lead lumen, guiding delivery of the distal tip of the medical electrical lead to a target site within the coronary venous system though the hemostasis valve and the delivery sheath, wherein, subsequent to the distal tip being delivered to the target sight, the hemostasis valve is advanced over the connector and the anchoring sleeve of the medical electrical lead to remove the hemostasis valve from the medical electrical lead. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
