摘要:
A lead assembly for an implantable medical device includes a lead body having a proximal end and a distal end. One or more connectors at the proximal end of the lead body are each adapted for connection to a pulse generator. One or more conductive elements are coupled to the one or more connectors at the proximal end and extend through the lead body to the distal end. Each of the one or more conductive elements includes an electrode coil that extends from the distal end of the lead body that is formed into a helix having a diameter greater than a diameter of the electrode coil.

An electrical implantable lead includes an elongated lead body having a plurality of lumens therein, including at least one linear lumen and at least one planar, non-linear lumen and a plurality of conductor cables disposed within the plurality of lumens. The electrical implantable lead further includes a terminal connector coupled to a proximal end of the lead body, the terminal connector being in electrical communication with at least one of the plurality of conductor cables. Further, the electrical implantable lead includes at least one electrode coupled to the lead body, the at least one electrode in electrical communication with at least one of the plurality of conductor cables. In accordance with various embodiments, the at least one non-linear lumen extends longitudinally along a portion of the lead body and includes a plurality or crests and a plurality of troughs.

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.

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.

摘要:
A cardiac lead adapted for fixation at least partially within a cardiac vessel. The lead includes, in one embodiment, an elongate lead body defining a proximal region and a distal region including a distal end region having at least one electrode and a distal tip. The distal end region is configured such that the electrode and the distal tip can be implanted in the cardiac vessel. Stiffening structures in the distal region of the lead are adapted to stiffen selected portions of the lead for fixation of the electrode within the cardiac vessel. In some embodiments, the stiffening structures include an implantable member adapted to be implanted in a lumen of the lead. In other embodiments, the stiffening structures include a sheath adapted to be deployed over the lead body. In still other embodiments, the stiffening structures are integral to the lead and/or the lead body.
