Abstract:
An implantable lead having a distal assembly including a coupler, a fixation helix secured to the coupler, a housing in which the fixation helix and the coupler are disposed, and a resilient seal that is fixedly secured to the coupler between proximal and distal ends thereof and able to translate with the coupler relative to the housing. The seal is positioned to sealingly engage an internal surface of the housing. When the coupler is translated such that the fixation helix is in a fully extended position, the seal is positioned to substantially seal off the housing to prevent tissue ingrowth.
