| 摘要 |
The disclosure is directed to a deep brain stimulation (DBS) lead having a distal end for providing therapeutic electrical stimulation to tissue in a stimulation target area of a patient's brain, comprising an array of one or more stimulation elements and sensing elements located at the distal end of the lead; each of the one or more stimulation elements is capable of providing electrical stimulation to the brain tissue in the target area; and each of the one or more sensing elements is capable of detecting electrical signals produced by nerve cells within the brain; wherein after the first implantation of the lead into the brain along a trajectory that is pre-determined by non-surgical procedures, the array of stimulation and sensing elements is capable of facilitating the location of the target area and the determination for each of the stimulation elements of the required stimulation parameters needed to provide the therapeutic stimulation to the brain tissue in the stimulation target area, without requiring any additional implantations of the lead after the first implantation. A stimulation system including the DBS lead and a pulse generator is disclosed. Also disclosed is a method of providing therapeutic DBS to brain tissue using the lead. |
