ATRAUMATIC LEAD FOR DEEP BRAIN STIMULATION

摘要

The present invention relates to an implantable lead (100) for deep brain stimulation comprising: - a longitudinal shaft (2) formed from electrical insulating material having a proximal (12) and distal end (20); - two or more ring-shaped electrical contacts (4, 4', 4", 4'"); - wherein each electrical contact (4, 4', 4", 4'") extends circumferentially around the longitudinal axis (A-A') of the shaft (2), and the electrical contacts (4, 4', 4", 4'") are dispersed longitudinally on the shaft (2) in electrical isolation; - wherein the outer surface of at least one electrical contact (4, 4', 4", 4'") is recessed compared with the outer surfaces of the flanking regions (6, 6', 6", 6"', 6"") of the shaft (2); - wherein at least one of the electrical contacts (4, 4', 4", 4"') is electrically connected to a conductor (10, 10', 10", 10"') that exits the lead at the proximal end (12) of the shaft (2), the connection being via an electrical joint located exclusively on the inner circumferential surface of the electrical contact (4, 4', 4", 4"'). It further relates to a kit and a method of manufacture of the lead.
