Abstract:
A method for the medical treatment of the neurological system in which a medical treatment instrument is inserted to a targeted treatment site in the neurological system along a nonlinear insertion route, said neurological system having neurological zones to be avoided by said medical treatment instrument, said method comprising the steps of:creating a surgical opening in the body;providing an outer tubular member positioned within said medical treatment instrument;positioning said outer tubular member through said surgical opening along a first insertion direction into said neurological system;providing a superelastic inner tubular member positioned within said outer tubular member, said inner tubular member having a distal end, said distal end having a curvature;advancing said inner tubular member into said neurological system along a curvilinear trajectory, said distal end of said inner tubular member defining a second insertion direction, said second insertion direction pointing towards said targeted treatment site, said advancing of said inner tubular member avoiding said neurological zones;providing an innermost member positioned in said superelastic inner tubular member;moving said innermost member into said neurological system along said second insertion direction to said targeted treatment site, said innermost member also avoiding said neurological zones during said moving step; andapplying treatment via said medical treatment instrument to said targeted treatment site.
