Abstract
An infusion catheter is provided for delivering treatment fluids including medicaments, drugs, pharmaceuticals, cancer treatment agents and the like directly to a location within a living body such as within a vessel or body cavity. Electro-osmotic infusion is carried out by iontophoretic and/or iontohydrokinesis procedures. The infusion catheter includes both an internal electrode and an integral electrode, both of which are components of or closely associated with a distal portion of the catheter itself. When electrically joined to an EMF source, the electrodes are oppositely charged. The treatment fluid or components of the treatment fluid have an electrical charge which is the same as the internal electrode, as a result of which the medicament moves away from the internal electrode and to the body component being treated.
