Abstract
A stimulator includes a support layer, a coil supported by the support layer, the coil extending around a central area, and a plurality of pillars supported by the support layer in the central area.
Claims23
A stimulator comprising:
- a support layer;
- a coil supported by the support layer, the coil extending around a central area to form multiple turns around the central area;
- and
- a plurality of pillars supported by the support layer in the central area such that each turn of the multiple turns surrounds each pillar of the plurality of pillars.

A method of medical treatment comprising:
- placing a magnetic field generator near target tissue, the magnetic field generator comprising:
- a conductive coil that wraps around a central volume to form a plurality of turns around the central volume;
- and
- a plurality of pillars located within the central volume such that each turn of the plurality of turns surrounds all of the pillars of the plurality of pillars;
- and
- applying a series of current pulses to the conductive coil so as to generate a magnetic field that passes through the plurality of pillars and interacts with the target tissue.
3 more elements
A medical treatment device comprising:
- a plurality of magnetic pillars;
- a coil wrapping around the plurality of magnetic pillars, the coil comprising a plurality of turns such that each turn surrounds all of the magnetic pillars of the plurality of magnetic pillars;
- and
- a controller configured to apply a current to the coil to generate a magnetic field that passes through the plurality of magnetic pillars.
1 more element
A stimulator comprising:
