Claim 18:
19. A method comprising:
receiving, by an adapter, a proximal portion of an implantable medical lead, the implantable medical lead comprising an electrode at a distal end of the implantable medical lead, and a lead electrical connector at the proximal portion of the implantable medical lead, the lead electrical connector electrically coupled to the electrode;
rotating, by the implantable medical lead, to advance the electrode for implantation in patient tissue, wherein the adapter comprises:
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; 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 rotates about 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 rotationally fixed relative to the adapter body when the proximal portion of the implantable medical lead is rotated; and

receiving, by a test device electrically coupled to the adapter, signals sensed via the electrode during the rotation of the implantable medical lead.
