MRI compatible implantable lead

摘要

An implantable lead is provided that comprises a lead body configured to be implanted in a patient, the lead body having a distal end and a proximal end, and a lumen extending between the distal and proximal ends; a connector assembly provided at the proximal end of the lead body, the connector assembly configured to connect to an implantable medical device; an electrode provided along the lead body, the electrode configured to at least one of deliver stimulating pulses and sense electrical activity, the electrode having a length extending between a proximal end and a distal end of the electrode; a conductor cable located within the lead body and extending at least partially along a length of the lead body; and an connection node electrically connecting the cable to the electrode at an intermediate point along the length of the electrode. The connection node is disposed at a position intermediate between the proximal and distal ends of the electrode.
