Lead having thin distal end portion |
| 摘要 |
A deep brain stimulation lead includes a distal end portion having a length of greater than 5 millimeters and a largest outer diametric dimension of 1 millimeter or less. One or more electrodes are disposed at the distal end portion. The lead also includes a proximal end portion having one or more contacts electrically coupled to the one or more electrodes. The lead further includes a mid portion between the proximal end portion and the distal end portion. The mid portion has an outer diametric dimension of greater than 1 millimeter and is configured and positioned to be located in proximity to a burr hole of a skull of patient when the distal end portion is positioned in the brain of the patient at a location to deliver a signal to a target region. |

1. An implantable brain stimulation lead comprising:
a distal end portion having a length of 20 millimeters or greater and a largest outer diametric dimension of 1 millimeter or less; one or more electrodes disposed at the distal end portion; a proximal end portion having one or more contacts electrically coupled to the one or more electrodes; and a mid portion between the proximal end portion and the distal end portion, the mid portion having an outer diametric dimension of greater than 1 millimeter and configured and positioned to be located at a burr hole of a skull of a patient when the distal end portion is positioned in the brain of the patient, wherein the distal end portion is the only portion extending distally from the mid portion. |
