Title: MEDICAL IMPLANTABLE LEAD
Abstract:
The invention relates to a medical implantable lead of the kind being adapted to be implanted into a human or animal body for monitoring and/or controlling of an organ inside the body by means of an electric monitoring and/or controlling device. The lead comprises a connector including a rotatable control member in a proximal end of the lead, a rotatable and extendable helix (4) which is arranged in a tubular header (3) in a distal end of the lead and which functions both as a fixating member, for fixation of the distal end of the lead to the organ inside the body by being screwed into and embedded in tissue, and as an electrode for receiving and/or transmitting electrical signals from and to the tissue, respectively, and at least one conductor coil (8) including at least one electrically conducting wire, which is rotatably arranged within the lead and connected to the rotatable control member in the proximal end as well as to the helix in the distal end and which electrically connects the helix to the connector. The lead also comprises a torque transferring member (15), which is rotatably arranged within the lead and jointly together with the conductor coil (8) connected to the rotatable control member and the helix (4) such that the torque transferring member and the conductor coil will rotate simultaneously together when rotating the helix by means of the rotatable control member.
