Abstract
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.

A computer-readable medium for use with a patient, having instructions that, when executed:
- receive information corresponding to an impedance of a circuit, the circuit including an electrical contact and patient tissue adjacent to the electrical contact;
- compare the impedance to a predetermined criterion;
- and
- if the impedance meets the predetermined criterion, provide an indication that the patient's dura has been penetrated.

- compare the impedance to a predetermined criterion;
- if the impedance meets the predetermined criterion, provide an indication that the patient's dura has been penetrated;
- and
- if the impedance does not meet the predetermined criterion, provide an indication that the patient's dura has not been penetrated.
A computer-readable medium for use with a patient, having instructions that, when executed:
- receive information corresponding to an impedance of a circuit, the circuit including an electrical contact and patient tissue adjacent to the electrical contact;
- compare the impedance to a predetermined criterion;
- if the impedance meets the predetermined criterion, provide an indication that the patient's dura has been penetrated, wherein the predetermined criterion includes a reference impedance of 50 ohms or less.
