Abstract:
A method of in vivo introduction of molecules into living blood cells of a patient for therapeutic purposes, comprising the steps of:providing an inductance device including an induction coil, the induction coil comprising at least one conductor having opposite ends adapted for connection to an electrical power source and at least one turn forming a coil intermediate the ends;positioning said inductance device external of and closely adjacent to a body of the patient directly over a selected blood vessel for inducing an electric field at a preselected location within the selected blood vessel;infusing preselected ones of said molecules into the selected blood vessel upstream of the inductance device; andapplying time varying electric signals to the applied inductance device to generate time varying magnetic fields and repeatedly subject a quantity of blood flowing past the preselected location in the selected blood vessel to electric fields of a predetermined amplitude and duration, induced by the time varying magnetic fields, sufficient to make walls of preselected cells in said quantity of blood transiently permeable to permit the molecules to enter said preselected cells without killing said cells.
