Claim 14:
15. A medical delivery system for rotating an implantable lead, the medical delivery system comprising:
a lead delivery device having a proximal end and a distal end defining a longitudinal axis and a lumen, wherein the lead delivery device comprises:
a stereotactic collar defining a collar access at the proximal end; and
a cannula attached to the stereotactic collar and defining a distal opening at a distal end of the lead delivery device, the lumen extending from the collar access to the distal opening,
wherein the stereotactic collar is configured to rotate about the longitudinal axis,
wherein the stereotactic collar is configured to cause a rotation of the cannula about the longitudinal axis when the stereotactic collar rotates about the longitudinal axis,
wherein an inner surface of the cannula is configured to engage an exterior surface of the implantable lead when the implantable lead extends within the lumen and the stereotactic collar causes the rotation of the cannula, the inner surface configured such that the engagement causes a synchronous rotation of the implantable lead with the cannula about the longitudinal axis
wherein the cannula is configured to translate substantially parallel to the longitudinal axis relative to the implantable lead; and

a carrier configured to engage the lead delivery device,
wherein the carrier defines a carrier body,
wherein the carrier comprises: a drive mechanism configured to receive a torque and impart a portion of the torque to the lead delivery device to cause stereotactic collar to rotate relative to the carrier body and about the longitudinal axis when the carrier engages the lead delivery device, and
wherein the drive mechanism comprises:
a turn knob configured to receive the torque, wherein the turn knob is accessible from an exterior surface of the carrier; and
a turn enable having a first position and a second position, wherein the turn enable is configured to allow the drive mechanism to impart the portion of the torque to the lead delivery device in the first position and configured to prevent the drive mechanism from imparting the portion of the torque to the lead delivery device in the second position.
