Abstract: A medical electrical lead having an elongated lead body extending from a proximal end to a distal end, a first electrode positioned at the distal end of the lead body, a second electrode spaced proximally from the first electrode, the second electrode being a flexible conductive coil and having a distal end. A first electrode sleeve is coupled to the first electrode, and a second electrode sleeve is coupled to the second electrode and positioned within the proximal end of the lead body and proximal the distal end of the second electrode to provide flexibility in a distal lead body portion.

Abstract: A medical delivery system includes an outer catheter extending between a proximal end and a distal end; a suction device positioned at the outer catheter distal end and coupled to a suction conduit; a delivery catheter extending between a proximal end and a distal end, the delivery catheter having an outer diameter adapted to be advanced through the outer catheter; a sealing member positioned at the outer catheter proximal end adapted to form an air-tight seal with the delivery catheter outer diameter; a puncture tool having a distal sharpened tip adapted to be advanced through the delivery catheter and into a targeted implant site a controlled distance to form a puncture.

Abstract: A medical electrical lead for establishing an electrical connection with a tissue of the body, the lead having a lead body and a semi-cylindrical cuff. In the preferred embodiment the semi-cylindrical cuff features one or more electrodes. The semi-cylindrical cuff having a long flap which wraps about the cuff and a short flap which wraps about the long flap. The semi-cylindrical cuff is relatively stiff as compared to the short flap. The short flap, in turn, is relatively the same stiffness as the long flap. The stiffness of each flap may be varied, however, so that one is more or less than the other, and in turn, than the cuff. Through such a multi-flap construction the electrodes may be positioned proximal to a nerve in such a manner that the mechanically induced damage may be minimized or even entirely eliminated. Finally, a method of implanting such an electrode is also disclosed.

Abstract: A sensor is provided on a lead and senses various physical parameters that are indicative of a desired anatomical target, such as the coronary sinus. The data from the sensor is used to navigate to the anatomical target and/or confirm that the anatomical target has been reached. In one embodiment, the sensor is a temperature sensor and increased temperature values in and around the coronary sinus are used for navigational purposes.

Abstract: The invention is directed to a medical lead that includes a pivot element. The pivot element is disposed between a distal electrode and the body of the lead so that the distal electrode can move laterally relative to the lead body. In various embodiments, the pivot element can comprise a hinge element, a double-hinge element, a ball joint element, or the like. The distal electrode may comprise a helical element that can be implanted in tissue. Following implantation of the electrode, the pivot element can reduce stress on tissue surrounding the implantation site, and can decrease the chance of dislodgement of the electrode.
