1. A system comprising:
an implantable medical lead comprising:
an electrode at a distal end of the implantable medical lead; and
a lead electrical connector at a proximal portion of the implantable medical lead, the lead electrical connector electrically coupled to the electrode; and
an adapter comprising:
an adapter body configured to receive the proximal portion of the implantable medical lead, including the lead electrical connector, and allow rotation of the proximal portion relative to the adapter body when the proximal portion is received by the adapter body;
an adapter electrical connector configured to be electrically connected to a test device; and
a rotational electrical coupling within the adapter body, the rotational electrical coupling configured to electrically connect the lead electrical connector to the adapter electrical connector and comprising:
a first conductive component configured to be electrically connected to the lead electrical connector and rotatable within the adapter body with the proximal portion of the implantable medical lead, wherein the first conductive component is coaxial with a longitudinal axis of the proximal portion of the implantable medical lead, wherein the first conductive component is rotatable about the longitudinal axis with the proximal portion of the implantable medical lead when the proximal portion of the implantable medical lead is rotated, and wherein the first conductive component is further configured to move axially within the adapter body; and
a second conductive component electrically connected to the first conductive component and the adapter electrical connector, wherein the second conductive component is coaxial with the longitudinal axis of the proximal portion of the implantable medical lead, and wherein the second conductive component is rotationally fixed relative to the adapter body when the proximal portion of the implantable medical lead is rotated.
