Abstract
The present invention involves methods of stimulating tissue using one or more series of electrodes to apply energy through a combination of electrodes to stimulate various regions within an area of interest. Such an approach can triangulate areas where stimulation and/or treatment is needed for deep brain stimulation (DBS). In addition, the triangulation system and methods described herein can be applied to any portion of a body where stimulation of a particular area is required while using the vascular network to access tissue surrounding that particular area so that a combination of electrodes can be used to identify the region of interest that requires stimulation.
Claims19
A method of stimulating a cerebral tissue of a brain, where the cerebral tissue is associated with a brain activity of an individual, the method comprising:
- positioning a first series of electrodes in a first vascular location in a first region of the brain;
- positioning a second series of electrodes along a second vascular location a second region of the brain;
- where the first region of the brain and the second region of the brain are adjacent to and spaced from the region in the cerebral tissue of the brain that is associated with the brain activity, and where the first region of the brain is spaced from the second region of the brain;
- repeatedly applying stimulation energy to a plurality of combination of electrodes selected from the first series of electrodes and/or the second series of electrodes, where application of energy to each of combination of electrodes produces an associated stimulated area of cerebral tissue respectively associated with that combination of electrodes;
- and
- identifying a target combination of electrodes where the associated stimulated area of cerebral tissue affects the brain activity.
A method of stimulating a cerebral tissue of a brain, where the cerebral tissue is associated with a brain activity of an individual, the method comprising:
- positioning a first series of electrodes in a first vascular location in a first region of the brain;
- positioning a second series of electrodes along a second vascular location a second region of the brain;
- where the first region of the brain and the second region of the brain are adjacent to and spaced from the region in the cerebral tissue of the brain that is associated with the brain activity, and where the first region of the brain is spaced from the second region of the brain;
- repeatedly applying stimulation energy to a plurality of combination of electrodes selected from the first series of electrodes and/or the second series of electrodes, where application of energy to each of combination of electrodes produces an associated stimulated area of cerebral tissue respectively associated with that combination of electrodes;
- identifying a target combination of electrodes where the associated stimulated area of cerebral tissue affects the brain activity;
- and
- applying therapeutic energy to the associated stimulated area.
A method of applying stimulation to tissue in a body of an individual, the method comprising:
- positioning a first series of electrodes in a first vascular location in a first region of the body;
- positioning a second series of electrodes along a second vascular location in a second region of the body;
- where the first region of the tissue and the second region of the body are adjacent to and spaced from the target region, where the target region is associated with a bodily function, and where the first region of the body is spaced from the second region of the body;
- repeatedly applying stimulation energy to a plurality of combination of electrodes selected from the first series of electrodes and/or the second series of electrodes, where application of energy to each of combination of electrodes produces an associated stimulated area of a tissue region in the body that is associated with that combination of electrodes;
- and
- identifying a target combination of electrodes where the associated stimulated area of a tissue affects the bodily function.
