SYSTEM AND METHOD FOR IMPLANTATION OF LEAD AND ELECTRODES TO THE ENDOPELVIC PORTION OF THE PELVIC NERVES AND CONNECTION CABLE FOR ELECTRODE WITH DIRECTION MARKER

摘要

A collector electrode assembly which can be implanted by laparoscopy through the abdominal wall into the small pelvis of the human body includes a collector electrode for neurostimulation of nerves; a connection cable having an outer surface, said collector electrode being arranged at one end of said connection cable and comprising several outer segment electrodes which can be contacted individually and/or in groups and which are arranged axially one after another in the direction of the longitudinal extent of the collector electrode, wherein an insulating section is arranged axially between in each case two adjacent outer segment electrodes and permits electrical insulation of respective two adjacent outer segment electrodes; radially expandable fixing structures positioned on the collector electrode and radially expandable from a withdrawn position to a radially expanded position for fixing the collector electrode in place at said nerves; a visually perceptible direction marker on the outer surface of the connection cable, at least in a cable section which is spaced apart from axial ends of the connection cable and has an axial extent of at least 10 cm and/or at least 15% of total length of the connection cable, said direction marker indicating orientation of the connection cable to an operator using the assembly, and wherein the direction marker is designed and arranged in such a way that the identification of the orientation of the connection cable is possible at any desired axial section of the cable section having a maximum axial extent of 2 cm.
