    摘要: A seal adapted for use with medical devices is provided with a lead having a distal tip electrode. The distal tip of the lead is adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The lead can include a fixation helix for securing the electrode to cardiac tissue. The lead assembly can alternatively include an open lumen lead tip. A seal is provided within the lead tip assembly such that the seal is expanded to prevent or limit further entry of fluids through the lead tip. The seal includes an expandable matrix, such as a hydrogel. The seal is formed on or within the lead when the lead and the seal comes into contact with a fluid and expands. The seal is also formed as a plug which is deployed through the medical device, and expands as the plug absorbs fluid. A housing incorporating the seal can also be attached to a portion of the medical device to provide the seal.

    摘要: A method for allowing cardiac signals to be sensed and pacing pulse vectors to be delivered between two or more electrodes. In one embodiment, cardiac signals are sensed and pacing pulse vectors are delivered between least one of a first left ventricular electrode and a second left ventricular electrode. Alternatively, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrodes and a first supraventricular electrode. In addition, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrode, the first supraventricular electrode and a conductive housing. In an additional embodiment, a first right ventricular electrode is used to sense cardiac signals and provide pacing pulses with different combinations of the first and second left ventricular electrodes, the first supraventricular electrode and the housing.

    摘要: A lead for monitoring or stimulating cardiac activity is provided. The lead is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead body has one or more electrodes associated therewith. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and urged into intimate contact a vessel wall. A method for implanting the lead into the coronary vasculature is also provided, the method comprising the steps of inserting a stylet into the lead, inserting the lead into the coronary sinus, advancing the lead from the coronary sinus toward the toward the left atrium and into a coronary vein, removing the stylet, and sensing and pacing the heart. Alternatively, the method comprises placing a guide catheter into the coronary sinus, threading a guide wire into the coronary veins, pushing the lead over the guide wire and into the coronary sinus or the coronary vein, and sensing and pacing the heart via the lead in its implanted site in the coronary sinus or the coronary vein.

    摘要: A method for allowing cardiac signals to be sensed and pacing pulse vectors to be delivered between two or more electrodes. In one embodiment, cardiac signals are sensed and pacing pulse vectors are delivered between at least one of a first left ventricular electrode and a second left ventricular electrode. Alternatively, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrodes and a first supraventricular electrode. In addition, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrode, the first supraventricular electrode and a conductive housing.
