| 发明名称 | Systems and methods for detecting intrathecal penetration | ||
| 摘要 | Systems and methods for detecting intrathecal penetration are disclosed. A method in accordance with one embodiment includes detecting a value corresponding to an impedance of an electrical circuit that in turn includes an electrical contact located within the patient, and patient tissue adjacent to the electrical contact. The method further includes comparing the detected value to a predetermined criterion, and, if the detected value meets the predetermined criterion, identifying penetration of the patient's dura based at least in part on the detected value. | ||

| 主权项 | 1. A method for introducing a patient device, comprising: detecting a value corresponding to an impedance of an electrical circuit, the electrical circuit including: an electrical contact carried by an elongated flexible lead and located within the patient; andpatient tissue adjacent to the electrical contact; comparing the detected value to a predetermined criterion; if the detected value meets the predetermined criterion, identifying penetration of the patient's dura based at least in part on the detected value; and if the detected value does not meet the predetermined criterion, applying a therapeutic signal to the patient's nervous system via the elongated flexible lead. | ||
