Patent ID: 8723628

Claim:
A Y-shaped Transcranial Magnetic Stimulation (TMS) electromagnet configured to emit a focused magnetic field, the TMS electromagnet comprising: a first magnetic coil loop and a second magnetic coil loop arranged about a central axis; wherein the first magnetic coil loop is bent relative to the central axis and comprises a plurality of windings and wherein the second magnetic coil loop is bent relative to the central axis and comprises a plurality of windings, the first and second magnetic coil loops meeting at a vertex along the central axis; wherein the first magnetic coil loop comprises a first inner coil region at the vertex and the second magnetic coil loop comprises a second inner coil region at the vertex, the plurality of windings within the first inner coil region forming a column that is adjacent and parallel to a second column formed by the plurality of windings within the second inner coil region, the first and second columns aligned along a vertex plane; and wherein the first magnetic coil loop further comprises a first outer coil region extending from the vertex and the second magnetic coil loop further comprises a second outer coil region extending from the vertex, and an angle between the first outer coil region and the second outer coil region in the vertex plane is between about 30 degrees and about 120 degrees.
