Patent number: 12233257Abstract: An implantable lead having adjustable electrode locations and a system for controlling the same. The implantable lead may include a plurality of first electrodes exposed and formed at an upper part of a main body at given intervals, a plurality of second electrodes coupled to a stepped lower part of the main body and configured to deliver a stimulus signal to a core area into which the lead is inserted, and a plurality of signal lines embedded in the main body and configured to connect the first electrodes and the second electrodes in a one-to-one manner. In this case, a slot for coupling and up and down movement of the second electrodes may be formed in the lower part. As the second electrodes are individually moved along the slot by an external force acting on the signal lines, locations of the second electrodes in the lower part may be adjusted.Type: GrantFiled: January 6, 2021Date of Patent: February 25, 2025Assignee: SAMSUNG LIFE PUBLIC WELFARE FOUNDATIONInventors: Eun Kyoung Park, Tae Kyung Kim, Tae Woo Kim, Min Hee Kang, Dong Il Choi, Kyu Sung Lee
