    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 lead having an atraumatic tip is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and are biased toward a vessel wall by a preformed biased portion. Near the distal end, the lead has an optional tapered portion and a flexible portion, where the flexible portion is more flexible than the biased portion.

    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.
