  • Publication number: 20190269929
    Abstract: A method, system and device for implanting an electrode assembly of an implantable medical device in a patient's heart. Positioning one or more radiopaque markers in a coronary sinus of the patient's heart. Positioning, by using the one or more positioned radiopaque markers as a fluoroscopic visual reference, a distal tip of a delivery catheter within a right atrium of the patient's heart so that a distal opening of a lumen of the catheter is against a septal wall of the heart at a location between the ostium of the coronary sinus and the A-V nodal area of the right atrium, and so that the tip of the catheter is generally directed toward a left ventricle of the patient's heart. Advancing the electrode assembly through the lumen of the catheter and into the septal wall.

  • Patent number: 7287995
    Abstract: A lead connector arrangement includes a non-cylindrically shaped connector pin coupled to a lead conductor and a connector sleeve assembly for receiving the non-cylindrically shaped connector pin. The connector sleeve assembly includes an insert with an axial bore formed therein that complements the shape of the non-cylindrical connector pin. According to one embodiment, the non-cylindrical connector pin may be provided in the form of a triangular, square, rectangular, or hexagonal shape. The axial bore has a complimentary shape to receive the connector pin. When the connector pin is threaded through the connector sleeve assembly using a pull-wire device, the pull-wire device may be unscrewed from the connector pin without causing axial rotation of the lead conductor when the connector pin is fully inserted within the axial bore.

  • Patent number: 6836687
    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.

  • Patent number: 6733500
    Abstract: 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.

  • Patent number: 6705900
    Abstract: An improved connection system for coupling a device such as a pacemaker, cardioverter, defibrillator, nerve stimulator, muscle stimulator, implantable monitor or other medical device to a medical lead is disclosed. The connection system includes a coupling member designed to couple to the proximal end of the lead. This coupling member, which includes an inner lumen sized to form a press fit around the proximal end of the lead body, may be of a generally tubular construction. This coupling member includes connector means to enable a connector pin at the proximal end of the lead to mechanically and electrically couple to a device. The connector means may further include means for coupling both mechanically and electrically to a ring connector on the proximal end of a multi-polar lead. An insertion member may also be provided to allow the lead to be more easily inserted within the inner lumen of the coupling member.

  • Publication number: 20030199961
    Abstract: A method and apparatus for dynamically fixating and removing a lead in a vasculature of a body. At least one segmenting means such as a collar is disposed at a distal end of the lead forming a deployable actuable segment adapted to dynamically assume an engaging and retracted position. In an engaging position, the actuable segment dynamically and varyingly adapts into a shape or shapes to engage a vessel. In a retracted position the shape or shapes collapse thus maintaining the original geometry of the lead in the vasculature. The actuable segment assumes a deployed or retracted position based on the flexural condition of the segment, respectively.
