Abstract:
1. An implantable lead system, comprising: a lead comprising a lead body, the lead body comprising a proximal end, a distal end, and a midpoint equidistant from the proximal and distal ends; a cardiac electrode coupled to the lead body, the electrode and lead body configured for placement within a tunnel surgically formed in subcutaneous non-intrathoracic tissue; a plurality of fixation elements disposed along the lead body in a spaced relationship between the distal and proximal ends, at least one of the fixation elements situated proximal of the midpoint such that the at least one of the fixation elements is closer to the proximal end than the distal end of the lead body, the at least one of the fixation elements configured to facilitate fixation of a proximal portion of the lead body to a proximal portion of the tunnel, and at least one other of the fixation elements situated distal of the midpoint such that the at least one other of the fixation elements is closer to the distal end than the proximal end of the lead body, the at least one other of the fixation elements configured to facilitate fixation of a distal portion of the lead body to a distal portion of the tunnel; and a pharmacological agent provided along at least a major portion comprising at least a quarter of the lead body length, the pharmacological agent having a coverage that provides a temporary therapeutic treatment.
