1. An implantable medical lead comprising:
- an outer lead package comprising;
an outer insulating tubing running from a proximal lead portion to a distal lead portion and having a lumen; and
a lead header made of an electrically insulating material and having a header lumen; and
an inner lead package comprising;
a connector pin connectable to an implantable medical device;
a helical fixation element;
an inner conductor coil having a proximal end electrically coupled to said connector pin and a distal end electrically coupled to said helical fixation element;
a connector ring connectable to said implantable medical device;
a ring electrode;
an outer conductor coil having a proximal end electrically connected to said connector ring and a distal end electrically connected to said ring electrode; and
an inner insulating tubing coaxially arranged relative to and between said outer conductor coil and said inner conductor coil, wherein said inner lead package is at least partly arranged in said lumen of said outer insulating tubing and said header lumen, and said inner lead package is rotatable relative to said outer lead package to translate the fixation element relative to the fixed outer lead package.

Abstract
An implantable medical lead comprises an outer lead package with an outer insulating tubing and a lead header having a window in its lateral surface. An inner lead package is at least partly arranged in lumens of the outer insulating tubing and the lead header and comprises a helical fixation element connected to a connector pin by an inner conductor coil, and a ring electrode connected to a connector ring by an outer conductor coil. An inner insulating tubing is coaxially arranged between the inner and outer conductor coils. The inner lead package is rotatable relative to the outer lead package and the ring electrode is configured to be at least partly exposed through the window.
