Abstract
Methods of locating an optimal site within a brain of a patient for deep brain stimulation include positioning a guiding cannula in a lumen of a main cannula, passing a microelectrode through a lumen of the guiding cannula into the brain, adjusting an insertion depth and a longitudinal angle of the guiding cannula such that the microelectrode locates the optimal site for the deep brain stimulation, and passing a distal end of a macroelectrode or a deep brain stimulation lead through the lumen of the main cannula and into the brain at the optimal site.
Claims20
A method of locating an optimal site within a brain of a patient for deep brain stimulation, said method comprising:
- inserting a distal portion of a main cannula into said brain, said main cannula having a lumen;
- positioning a guiding cannula in said lumen of said main cannula, said guiding cannula comprising a lumen and a bent distal end portion;
- passing a microelectrode through said lumen of said guiding cannula into said brain;
- adjusting an insertion depth of said guiding cannula with a depth adjustment mechanism and a longitudinal angle of said guiding cannula with a longitudinal angle adjustment device such that said microelectrode locates said optimal site for said deep brain stimulation;
- and
- passing a distal end of a macroelectrode or a deep brain stimulation lead through said lumen of said main cannula and into said brain at said optimal site.
A method of locating an optimal site within a brain of a patient for deep brain stimulation, said method comprising:
- passing a microelectrode through a lumen of a guiding cannula and into said brain, said guiding cannula having a bent distal end portion;
- adjusting an insertion depth of said microelectrode within said brain;
- and
- adjusting a longitudinal angle of said microelectrode.
A method of locating an optimal site for deep brain stimulation, said method comprising:
- (a) inserting a portion of a main cannula into said brain, said main cannula having a lumen;
- (b) inserting a portion of a guiding cannula into said lumen of said main cannula, said guiding cannula having a lumen and a bent distal end portion;
- (c) adjusting a longitudinal angle of said guiding cannula;
- (d) adjusting an insertion depth of said guiding cannula while introducing a distal portion of said guiding cannula into said brain;
- (e) passing a microelectrode through said lumen of said guiding cannula into said brain such that said microelectrode locates said optimal site for deep brain stimulation (DBS);
- and
- (f) wherein if an optimal stimulation site is not located by said microelectrode, said method comprises retracting said microelectrode and said guiding cannula out of said brain and repeating steps (c), (d), (e) and (f).
