1. A method for detecting positioning of a probe in a tissue of a patient, comprising:
- providing a device comprising a housing having a proximal portion and a distal portion coupled to a probe, the device further comprising;
a pressure sensing system at least partially carried by the housing and comprising a processing unit coupled with a pressure sensor so as to receive signal from the pressure sensor and determine from the received signal a pressure value of an environment about a distal portion of the coupled probe; and
an output unit carried by the housing and comprising a visual display, the output unit coupled to the pressure sensing system so as to receive pressure value signal and output to the visual display a reporting signal indicating the determined pressure value and/or positioning of the probe in the tissue of the patient;
advancing the device distally such that a distal portion of a probe advances through the tissue of the patient and toward the patient'"'"'s spinal canal;
detecting a change in pressure about the distal portion of the coupled probe during advancing indicating probe positioning in the patient'"'"'s spinal canal, and outputting corresponding reporting signal to the visual display.

Abstract
Methods and devices for detecting positioning of a probe in a tissue of a patient. A method can include providing a detection device; advancing a device coupled probe through the tissue of the patient and toward the patient'"'"'s spinal canal; detecting a change in pressure about the distal portion of the coupled probe during advancing, where the detected pressure change indicates probe positioning in the patient'"'"'s spinal canal; outputting the detected pressure change or indication of probe positioning to a visual display.

18. A device for detecting positioning of a coupled probe in a spinal canal of a patient, the device comprising:
-
a housing having a distal portion with a first port that is detachably couplable to a probe, and a proximal portion; a pressure sensing system at least partially carried by the housing and comprising a processing unit coupled with a pressure sensor so as to receive signal from the pressure sensor and determine from the received signal a pressure value of an environment about a distal portion of the coupled probe; and an output unit carried by the housing and comprising a visual display, the output unit coupled to the pressure sensing system so as to receive pressure value signal and output to the visual display a reporting signal indicating the determined pressure value and/or positioning of the probe in a spinal canal of the patient, wherein the pressure sensing system, processor, and output unit are disposed substantially between the first port and the proximal portion of the housing. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
