A neural intervention system,comprising: a) a guide tube comprising a guide tube sidewall extending along a longitudinal axis A-A from a proximal guide tube portion having a proximal guide tube end to a distal guide tube portion having a distal guide tube end, wherein a tube lumen extends from the proximal guide tube end to at least the guide tube portion; b) at least one deployment channel disposed inside the guide tube, the deployment channel comprising a channel sidewall defining a channel lumen extending from a proximal channel open end to a distal channel open end as an open port at the guide tube sidewall, wherein the proximal channel end resides along a first imaginary plane aligned substantially perpendicular to the longitudinal axis; c) at least one neural probe extending from a proximal probe end to a distal probe portion having a distal probe end, wherein the distal probe portion has at least one electrode configured for electrical stimulation of body tissue or recording of biological characteristics, and wherein at least the distal probe end is received in the deployment channel; d) an actuation mechanism (48, 50) having a length extending from a proximal actuation end to a distal actuation portion, e) wherein with the distal probe end received in the deployment lumen and the proximal probe end connected to the distal actuation portion, the proximal actuation portion is movable in a distal direction along the longitudinal axis to cause the at least one neural probe to move through the deployment channel and out the distal channel open end to thereby move the at least one electrode of the probe into a body tissue; characterized in that: the neural probe comprises a tape spring-type carrier such that: a) when in an unstressed condition extending in a substantially axial direction, the tape spring-type carrier has a curved cross-section perpendicular to the carrier length; b) when in a stressed condition bent out of alignment with an axial direction, the tape spring-type carrier has a linear cross-sectional shape perpendicular to the carrier length. a) a guide tube comprising a guide tube sidewall extending along a longitudinal axis A-A from a proximal guide tube portion having a proximal guide tube end to a distal guide tube portion having a distal guide tube end, wherein a tube lumen extends from the proximal guide tube end to at least the guide tube portion; b) at least one deployment channel disposed inside the guide tube, the deployment channel comprising a channel sidewall defining a channel lumen extending from a proximal channel open end to a distal channel open end as an open port at the guide tube sidewall, wherein the proximal channel end resides along a first imaginary plane aligned substantially perpendicular to the longitudinal axis; c) at least one neural probe extending from a proximal probe end to a distal probe portion having a distal probe end, wherein the distal probe portion has at least one electrode configured for electrical stimulation of body tissue or recording of biological characteristics, and wherein at least the distal probe end is received in the deployment channel; d) an actuation mechanism (48, 50) having a length extending from a proximal actuation end to a distal actuation portion, e) wherein with the distal probe end received in the deployment lumen and the proximal probe end connected to the distal actuation portion, the proximal actuation portion is movable in a distal direction along the longitudinal axis to cause the at least one neural probe to move through the deployment channel and out the distal channel open end to thereby move the at least one electrode of the probe into a body tissue; the neural probe comprises a tape spring-type carrier such that: a) when in an unstressed condition extending in a substantially axial direction, the tape spring-type carrier has a curved cross-section perpendicular to the carrier length; b) when in a stressed condition bent out of alignment with an axial direction, the tape spring-type carrier has a linear cross-sectional shape perpendicular to the carrier length. a) when in an unstressed condition extending in a substantially axial direction, the tape spring-type carrier has a curved cross-section perpendicular to the carrier length; b) when in a stressed condition bent out of alignment with an axial direction, the tape spring-type carrier has a linear cross-sectional shape perpendicular to the carrier length.
