    摘要： This document discusses, among other things, a lead assembly including a lead body, at least one conductor extending through the lead body, and a covering having varied material properties. In an example, the covering is made by forming pieces of material having varied material properties. In another example, the covering is made by varying parameters such as heat or tension during wrapping of a piece of material onto a lead assembly.

    摘要： This document discusses, among other things, a lead assembly including a lead body, a first conductor extending through the lead body and coupled to a first electrode, a second conductor extending through the lead body and coupled to a second electrode, and a multi-filar coil extending through the lead body. The multi-filar coil includes electrically independent first and second filars respectively coupled to first and second sensing or pacing electrodes. In an example, the second filar of the multi-filar coil is substantially coaxial with the first filar. An example method includes extending first and second conductors and a multi-filar coil through lumens in a lead body and coupling electrodes to the conductors and coils.

    摘要： A medical electrical lead employs a load bearing sleeve arrangement. A medical electrical lead includes an outer sleeve, having proximal and distal ends, and is formed of a first material. At least one electrical conductor is situated within the outer sleeve and extends between the proximal and distal ends of the outer sleeve. At least one electrode is electrically coupled to the electrical conductor. A load bearing sleeve extends between the proximal and distal ends of the outer sleeve. The load bearing sleeve is formed of a second material different from the first material. The load bearing sleeve offers resistance to axial loading forces applied to the lead. The load bearing sleeve can be coextensive with the outer sleeve or extend along at least the majority of the length of the outer sleeve.

    摘要： An implantable lead assembly includes a lead body extending from a proximal end to a distal end having an intermediate portion therebetween, where the lead body includes an insulating layer. A conductor is disposed within the insulating layer and the insulating layer surrounds the conductor. An electrode is coupled to the lead body, and the electrode is in electrical communication with the conductor. At least one conductive sleeve is disposed within the insulating layer. The at least one conductive sleeve surrounds the conductor and is electrically isolated from the electrode. The at least one conductive sleeve has a first impedance value in a first condition.

    摘要： A surface covering including a primary layer of a porous polymer structure and a secondary surface covering one or both of a metallic element layer and a hydrophilic layer is positioned over the surface of an ablation electrode. The pores of the surface covering are sized such that blood platelets are prevented from contacting the surface of the electrode while physiological fluid is allowed to pass through and contact the electrode surface to hereby provide a conduction path for current from the electrodes. The surface covering may further include an electrically non-conductive and thermally conductive portion positioned over another portion of the electrode to prevent alternate or non-intended site ablations.
