摘要： A lead body includes an electrode coupled to an intermediate portion of the lead body. A distal end of the lead includes a pre-formed, biased shape adapted to passively fixate the distal end of the lead within a pulmonary artery with the electrode positioned in the right ventricle or ventricular outflow tract. The lead body can include a pre-formed J-shape, with the electrode coupled to the intermediate portion of the lead body and located distally from a bottom of the pre-formed J-shape. The lead body can include a section of the intermediate portion of the lead body being less stiff than adjacent sections of the lead body with the electrode coupled to the intermediate portion of the lead body and located distally from the less stiff section.

摘要： This document discusses, among other things, a lead body extending longitudinally along a lead axis, a driver axially displaceable relative to the lead body, and a driven member coupled to the lead body and displaceable away from the lead axis. The driven member at least partially defines an expandable passage having at least one internal dimension. The driver is displaceable into the expandable passage and has at least one outer dimension that is larger than the at least one internal dimension of the expandable passage. An example method includes disposing a first member having a first cross-section in a lead assembly having a lead axis, an expandable passage, and a displaceable member proximate the expandable passage. The method further includes urging the first member into the expandable passage in the lead assembly, and urging the displaceable member away from the lead axis to expand the expandable passage.

The lead further includes an inner lead portion having a pin adapted to mechanically engage the internal bore. The pin is adapted for electrically coupling with a longitudinally-extending conductive member sized to fit within the internal longitudinal lumen. A method of using the lead.

摘要： An implantable lead comprises a lead body extending from a lead proximal end portion to a lead distal end portion. The lead body includes one or more longitudinally extending lumens. A conductor is received in, and extends along, a lumen. In varying examples, the implantable lead further comprises a tubular electrode co-axial with, and overlying portions of, the lead body. In one example, a lumen wall is sized and shaped to urge an electrically conductive interposer coupled with the conductor toward an inner surface of the electrode. In another example, a ring member is disposed within a lumen and the conductor is drawn and coupled thereto. In yet another example, an electrically conductive connector couples a first and a second conductor via grooves or threads. In a further example, an axial support member couples a distal end electrode and the lead body. Methods associated with the foregoing are also discussed.

摘要： A lead assembly includes an elongate body having a conductor electrically coupled with an electrode coupled to the elongate body. The lead assembly includes a push tube extending along at least a portion of the elongate body. A distal tip is coupled to the elongate body substantially adjacent to the distal end of the elongate body. The distal tip is sized and shaped to couple with a push tube distal end. In one option, the distal tip includes a seat to receive the push tube distal end. In another option, the seat is a side rail seat and a guide wire extends along the elongate body and is slidably coupled with the side rail seat. The lead assembly includes, optionally, an active fixation device slidably coupled with a portion of the elongate body, and the active fixation device is sized and shaped to couple with the push tube.
