Rotatable lead connectors

A method comprising:

• rotating, by an implantable medical lead, to advance an electrode, for implantation in patient tissue, of the implantable medical lead, wherein the implantable medical lead comprises:
• a lead body comprising a first conductor extending from a proximal portion of the implantable medical lead to a distal portion of the implantable medical lead;
• an electrode at the distal portion of the implantable medical lead;
• a lead electrical connector at the proximal portion of the implantable medical lead, wherein the lead electrical connector is configured to establish electrical communication between a test device and the electrode;
• and
• a rotational electrical coupling, wherein at least a portion of the rotational electrical coupling is mechanically supported by the lead electrical connector, and wherein the rotational electrical coupling comprises:
• a first conductive component electrically connected to the electrode by the first conductor, wherein the first conductive component is rotationally fixed to the lead body;
• and
• a second conductive component electrically connected to the first conductive component, wherein the second conductive component is configured to establish electrical communication with the test device via a second conductor that electrically connects the second conductive component to the test device, wherein the first conductive component and the lead body are configured to rotate relative to the second conductive component, wherein the second conductive component is electrically connected to the electrode by the first conductive component, wherein the electrode is configured to be advanced by rotating the implantable medical lead including the lead body comprising the first conductor, the lead electrical connector, and the electrode, and wherein the rotational electrical coupling is configured to allow the implantable medical lead to rotate relative to the second conductor that electrically connects the second conductive component to the test device;
• and
• receiving, by the test device, signals sensed via the electrode during the rotation of the implantable medical lead.
