DEFINITION

Classification: 604/501

Enhanced absorption of therapeutic material internally using iontophoretic treatment:

(under subclass 500) Subject matter for a process of subjecting the patient to an in-situ electromagnetic field to facilitate the transfer of a body treating composition to endothelial cells cellular membranes, body tissue, internal organs or benign and malignant tissue growths.

(1) Note. Endothelial cells are those cells, which line the insides of blood or lymph vessels and some other closed cavities.

(2) Note. Methods disclosing the injection of contrast mediums are not treating materials as such and should be placed with the appropriate diagnostic device.
