  • Publication number: 20050137672
    Abstract: The present invention is a lead for use in connection with a myocardial lead attachment system of the type having an anchor for engaging the heart and a tether extending from the anchor. The lead includes a lead body having a proximal end, a distal end and a lumen for accepting the tether. A tapered tip is separate from the lead and positioned adjacent the distal end of the lead. The tip has a longitudinal through-hole for accepting the tether.

  • Publication number: 20050131509
    Abstract: A method includes sandblasting an electrode surface, applying a conductive oxide precursor solution to the electrode surface, and heating the electrode for at least 5 minutes at a temperature between 350 degrees C. and 550 degrees C. to convert the precursor solution into an oxide coating. One method includes applying a composite material including a conductive component and a non-conductive component to an electrode and curing the composite material to form a coating on the electrode. One method includes providing a metallic oxide coating on an electrode surface and applying a galvanostatic treatment to the electrode to increase the effective surface area of the metallic oxide coating.

  • Publication number: 20050119718
    Abstract: A myocardial lead attachment system for securing a distal end of a lead within a myocardium of a patient's heart. The system includes a lead body, an anchor mechanism formed of a bioabsorbable or biodegradable polymer for engaging a surface of the patient's heart and a surface feature formed on a portion of the lead body for promoting formation of scar tissue around said portion of the lead body.

  • Publication number: 20050113900
    Abstract: The present invention is a myocardial lead attachment system and method for securing a distal end of a lead within the myocardium of a patient's heart. The system includes an anchor, a tether coupled at a distal end to the anchor and a lead body. The lead body has a proximal end, a distal end, and a lumen extending therethrough for receiving the tether. A fixation mechanism is at the distal end of the lead body, and is adapted to collapse to a first configuration during implantation and deploy to a second configuration after implantation.

  • Publication number: 20050113901
    Abstract: The present invention is a myocardial lead attachment system for securing a distal end of a lead within a myocardium of a patient's heart. The system includes an anchor, a tether coupled to the anchor, and a delivery instrument for receiving and advancing the anchor through a tract in the heart from a proximal entrance site to a distal exit site in such a manner that the tether extends proximally from the anchor through the tract. The delivery instrument includes a needle having a distal tip and a nest. The nest is positioned proximal to the distal tip and is sized to receive the anchor. The delivery instrument further includes an ejection mechanism for ejecting the anchor from the nest.

  • Publication number: 20050085885
    Abstract: 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.

  • Publication number: 20050070768
    Abstract: An apparatus includes an implantable device, such as a chronically implantable device that has a device body. One or more chemical sensors are coupled with the device body. A drug eluting substance is disposed at a location including at least one of on, directly adjacent, or near the one or more chemical sensors, where the drug eluting substance prevents fibrotic growth on the one or more chemical sensors.
