Patent ID: 8900224

Claim:
A kit for puncturing a wall of a cardiac septum, comprising: a screw lead including: a lead body having a sheath of a deformable material; a proximal end having an electrical connector; a distal end having a lead head including an electrode comprising a projecting helical screw, said projecting helical screw having a first conductive part and a second electrically isolated part, the second electrically isolated part having a traction function for penetrating the septum wall end in response to a screw motion applied to the lead head, the first conductive part having a septum wall cutting function for delivering a controlled radio-frequency energy to the septum wall concurrently with a screw motion applied to the lead head, said radio-frequency energy being controlled to puncture said septum wall whereby the lead passes through the punctured septum wall; and a conductor extending along the sheath, electrically connecting said electrical connector and the first conductive part of the projecting helical screw; and a radio-frequency puncture generator having a controlled radio-frequency energy for puncturing a septum wall and an output to connect to said lead electrical connector; wherein the screw lead is a detection/stimulation lead, and said electrode of the lead head comprises a detection/stimulation electrode.
