IPC: A61N1/32
Filed: 2019-08-22
Granted: 2023-04-27
Abstract: Certain substances (e.g., large molecules) that ordinarily cannot traverse the blood brain barrier can be introduced into the brain by applying an alternating electric field to the brain for a period of time, wherein the frequency of the alternating electric field is selected so that application of the alternating electric field increases permeability of the blood brain barrier.
