摘要： 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 multip le left heart sites.

摘要： An electrical medical lead is provided having two or more electrodes, electrically insulated from each other and electrically coupled to individually insulated filars in a multi-filar coiled conductor. When the le ad is used with a medical device equipped with a switch matrix, electrodes are selected individually or simultaneously to serve as an anode or cathode in a ny unipolar, bipolar or multi-polar configuration for delivering stimulation and/or sensing signals in excitable tissue. In one embodiment, a tip electro de array is expandable for improving electrode contact with targeted tissue and stabilizing lead position.

摘要： 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.

摘要： A lead connector arrangement includes a non-cylindrically shaped connector p in coupled to a lead conductor and a connector sleeve assembly for receiving th e non-cylindrically shaped connector pin. The connector sleeve assembly includ es an insert with an axial bore formed therein that complements the shape of th e non-cylindrical connector pin. According to one embodiment, the non- cylindrical connector pin may be provided in the form of a triangular, squar e, 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 le ad conductor when the connector pin is fully inserted within the axial bore.

摘要： An automated identification and configuration system for use with an implantable medical device (IMD) is disclosed. The system includes a first communication circuit that is attached to, or otherwise carried by, a detachable component associated with the IMD such as a medical lead. The communication circuit stores data such as model numbers, serial numbers, technical data, and/or calibration information that describes the additional component. This information may be transferred by the first communications circuit to a second communications circuit that is external to the additiona l component. This transferred data can be used to automatically configure the internal circuitry and connection functions of the IMD to properly interface with, and support, the additional component. The data may further be entered into a patient record on an external programmer, or may be transferred to a central storage location to be generally accessible to health care providers . In one embodiment, the first communication circuit is a passive RF transponder. This first communication circuit may include a receiver as well as a transmitter to allow the circuit to programmably receive data at the ti me of component manufacture.

摘要： An implantable sensing device includes a sensing element and a mounting element. The mounting element has a first end and a second end with a longitudinal axis therethrough. The sensing element is positioned at the first end of the mounting element with the mounting element having a length that is adjustable along the longitudinal axis. The mounting element includes a sleeve having a first open end and a second open end with the longitudinal axis therethrough. The sensing element is positioned in the second open end and includes a lead body connected thereto extending through the second open end. The sleeve includes an outer sleeve member coupled for adjustment along the longitudinal axis with respect to an inner sleeve member. Further, the mounting element may include a flexible element about the first open end extending outwardly relative to the longitudinal axis and a flange element extending outwardly relative to the longitudinal axis from at least a portion of the second end. The device can be implanted in a bone with the flange element and the flexible element for direct or indirect contact with the anterior and posterior surface of the bone.

摘要： One embodiment of the invention comprises an intravenous medical electrical lead that includes an elongated lead body. The elongated lead body comprises a length between a proximal end and a shaped distal end, The lead body includes a longitudinal axis extending between the proximal end and the shaped distal end. The lead body has an outer circumference with a set of electrodes circumferentially spaced apart. Each electrode includes an electrically active portion and an insulated portion at an outer circumference of the electrode. If the lead body rotates within the delivery catheter, the lead body is configured to rotate back into a position such that the electrically active portion of a set of electrodes faces myocardial tissue when exiting the guide catheter while the insulated portion of electrode are diametrically opposed to neural tissue such as the phrenic nerve.

摘要： 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.
