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： Medical electrical leads are provided including fixation features for acute and chronic fixation of a portion of the respective leads within the cardiac venous system. The medical electrical lead includes an elongate body having proximal and distal regions. Tissue contacting portions are selectively located in the distal region to contact an inner surface of the cardiac vessel when the lead is in an implanted position. The tissue contacting portion(s) include fixation features adapted to frictionally engage the inner surface of the cardiac vessel and promote tissue in-growth for chronic fixation. In some embodiments, the fixation features are detachable from the lead such that the lead can be extracted from its implanted position after tissue in-growth occurs.

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.
