US 12,766,319 B2 · Delivering tumor treating fields (TTFields) using implanted sheets of graphite

Abstract

Alternating electric fields (e.g., tumor treating fields, a.k.a. TTFields) may be applied to a target region in a subject's body via sheets of graphite that are implanted in the subject's body. One or more ports configured for affixation to the subject's body include or connect to one or more mating electrical connectors. Electrical conductors are positioned to route electrical signals between the electrical connector(s) and the sheets of graphite. The alternating electric fields are applied to the target region by applying (via the ports) an alternating voltage between two sheets of graphite that are positioned on opposite sides of the target region.

Dependent claims

A method of applying an alternating electric field to a target region in a subject's body, the method comprising:

applying an alternating voltage between a first sheet of graphite that has been previously implanted in the subject's body and a second sheet of graphite that has been previously implanted in the subject's body,
wherein the first sheet of graphite and the second sheet of graphite are positioned on opposite sides of the target region, and
wherein the first sheet of graphite has a first resistance in a direction that is perpendicular to its front face and the resistance of the sheet in directions parallel to the front face is less than half of the first resistance.
