Abstract
A medical urology device for drug delivery to the lining and deeper tissues of the ureter and kidney. The present invention features an electromotive drug administration (EMDA) catheter device for deploying a fluid to deep tissues of a patient. The device includes a catheter body with fenestrations along its distal length. The device may further comprise a multiport component for allowing access to the catheter body. The device may further comprise a conductive wire removably disposed through the multiport component within the catheter body. Fluid may be directed through the multiport component and the plurality of fenestrations to the body structure of the patient. Electrical stimulation directed through the conductive wire enhances the penetration of medications with the same polarity to electrical stimulation into a body structure of the patient to allow the fluid to penetrate deep tissues.
