摘要： A peel-away lead implant tool is described. The peel away lead implant tool is adapted to be disposed over the terminal connector of a lead during an implantation procedure to protect the terminal connector. The peel-away lead implant tool includes a flexible polymer sheath including electrical contacts formed in a contact region of the sheath. The electrical contacts can be either metal foil contacts or conductive polymer contacts and extend from an outer surface to an inner surface of the sheath such that when the testing apparatus is coupled to the lead implant tool, the electrical contacts are pressed into electrical contact with the ring electrodes located on the terminal connector. The lead implant tool also includes various removal means facilitating the easy removal of the implant tool from the terminal connector when the implantation procedure is complete.

摘要： A medical electrical lead adapted to be at least partially implanted in a cardiac vessel includes a fixation feature operable to change from an undeployed configuration to a deployed configuration in which the fixation feature is adapted to engage an inner surface of the cardiac vessel. A tendon is disposed within a lumen of the lead and is operatively connected to the fixation feature and adapted to cause the fixation feature to change from the undeployed configuration to the deployed configuration for acute and/or chronic fixation of the lead. In one embodiment, the fixation feature includes a deflectable region of the lead which in the deployed configuration causes a surface of the lead body to engage the inner surface of the cardiac vessel. In another embodiment, the fixation feature includes a radially expandable structure for engaging the inner surface of the vessel in the deployed configuration.

摘要： A medical electrical lead configured for use in stimulating the left side of the heart (i.e., the left ventricle). In one embodiment, the lead includes an elongate lead body including an inner surface. An inflatable member is disposed on the outer surface of the body between its proximal and distal ends, the inflatable member being adapted when inflated to impart a radial force on and frictionally engage a surface of the coronary sinus or coronary vein for fixation of the distal end of the lead therein. The lead further includes a conductive member extending from the proximal end toward the distal end, and an inner insulating layer positioned between the conductive member and the inner surface of the body. Separation between the inner insulating layer and the inner surface of the body defines an inflation lumen in fluid communication with the inflatable member.

摘要： A lead for sensing and pacing a left ventricle of the heart includes a lead body having a proximal portion and a distal portion, a lumen extending through the lead body, a conductor extending through the lead body from the proximal end to the distal end and an electrode disposed on the distal portion of the lead body and electrically coupled to the conductor. A distal tip of the lead body is continuously deflectable upon advancement and withdrawal of a stylet through the lumen at the distal portion to access a selected branch of the coronary sinus. The distal tip of the lead body may be offset before or after continuously deflecting the distal tip.

摘要： A cardiac lead assembly includes a sheath disposed over a majority of the outer surface of a cardiac lead body including a fixation helix located at its distal end. The sheath protects the fixation member during delivery of the lead assembly to a target location within a patient's heart. The sheath can include one or more means adapted for splitting the sheath such that the sheath can be removed from about the lead body once the lead has been implanted.

摘要： Implantable cardiac monitoring and stimulation methods and devices with epicardial leads having sensor feedback. A fixed or extendable/retractable sensor may be displaceable within the lead's lumen and configured to sense the presence of an anatomical feature or physiological parameter of cardiac tissue in proximity with the lead body's distal end. The sensor may include an ultrasonic sensing element, a perfusion sensor, a photoplethysmographic sensor, or a blood oximetry sensor. Methods of determining suitability for implanting a lead involve the steps of accessing an epicardial surface of the heart, and moving the cardiac lead to an implant site at the epicardial surface. A transmitted signal is directed at the implant site. A reflected signal is received, indicative of the presence of a blood vessel at the implant site. A determination may be made to determine whether the implant site is suitable or unsuitable based on the reflected signal.

摘要： In one embodiment, the present invention provides a cardiac lead device including a fixation mechanism slidably attached to the lead such that when the fixation mechanism is expanded into contact with a body lumen, the lead may be moved relative to the fixation mechanism if desired. Such lead movement may be limited by complimentary structure on the lead body and the fixation mechanism that prevents the lead from moving unless sufficient force is applied to the lead.
