Abstract
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.
