  • Patent number: 7031777
    Abstract: A bipolar cardiac vein lead and method of assembly is provided wherein the lead includes a flexible coil anode electrode such that the lead may be advanced through a tortuous pathway. The coil electrode is coupled to a conductor using a method of assembly that minimizes or eliminates rigid components, maintaining flexibility of the distal lead end. Multi-polar cardiac vein leads may include multiple flexible coil electrodes to achieve pacing and/or sensing in the left atrium and the left ventricle or at multiple left heart sites.

  • 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.

  • Publication number: 20040059404
    Abstract: An improved medical lead assembly and method of use is provided. The lead assembly includes a lead body, and a spring member positioned adjacent to the lead body. The spring member may be deployed a selectable amount to maintain the lead body in a fixed location within a patient's body. The spring member may be an expandable coil, a mesh structure that is similar to a stent, or any other similar device that may be positioned in a low-profile state during a lead implant procedure. After the lead is positioned at a target destination, the spring member may be deployed an amount that is selected based on the characteristics of the surrounding tissue, including vessel size. According to one aspect of the invention, the lead assembly may provide means for facilitating chronic lead extraction.

  • 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.

  • Patent number: 6567704
    Abstract: A medical electrical lead is disclosed having an inner lumen adapted to receive a stiffening member, and which is further adapted to deliver fluoro-visible media while the stiffening member is located within the inner lumen. According to one aspect of the invention, the stiffening member is a guide wire having an inner lumen. The inner lumen of the guide wire is used to deliver the contrast medium while the guide wire is in place within the lumen of the lead. In another embodiment, a stiffening member that is sized to occupy only a portion of the lumen of the lead is utilized. The non-occupied portion of the lumen is sized to be large enough to allow for the passage of fluoro-visible medium from an injection port at the proximal end of the lead to a delivery port at the distal end of the lead. According to one aspect of the invention, the lead includes a sealable member located at the distal end of the lumen of the lead to prevent the ingress of bodily fluids within this lead lumen.

  • Patent number: 6192280
    Abstract: A guidewire placed lead employing a seal at its distal end in order to prevent entry of body fluid into the lead. The seal is particularly designed to allow radial expansion of the outer circumference of the seal due to passage of the guidewire through the seal, reducing the force required to pass the guidewire through the seal, while retaining a good sealing characteristics. The seal may extend a distance distally from the tip electrode, and include a hollow, resilient, cup-shaped seal member, configured so that the seal can readily expand radially as the guidewire passes through it. Alternatively, the seal may be located within the body of the electrode and the electrode configured so that it may be radially or laterally expanded, also allowing radial expansion of the seal during passage of the guidewire. In this case, the electrode may be rendered expandable by means of one or more slits arranged along the electrode body, extending from a point proximal to the guidewire seal.
