Title (EN) INTERNAL TISSUE MEDICATION PERMEATING APPARATUS AND METHOD
(FR) APPAREIL ET PROCEDE INDUISANT LA PENETRATION D'UN MEDICAMENT DANS DES TISSUS INTERNES
Abstract:
(EN) A method and apparatus for selectively treating a targeted portion of internal body tissue of a patient by providing a balloon (14) with an internal electrode at a point adjacent the tissue to be treated and electrodes (13) external to the patient's body. Fluid containing ionic molecules is supplied to the balloon (10) between the internal electrode and the external electrodes. An electric field radiating outwardly from the internal electrode to the external electrodes (13) is created so that said fluid flows outwardly from the balloon (10) through pores (30) away from said internal electrode into the tissue to be treated.
(FR) Procédé et appareil permettant de traiter sélectivement une partie ciblée de tissus corporels internes d'un patient, consistant à doter un ballon (14) d'une électrode interne au niveau d'un point adjacent au tissu à traiter, et d'électrodes (13) externes au corps du patient. On achemine du fluide contenant des molécules ioniques au ballon (10) entre l'électrode interne et les électrodes externes. On crée un champ électrique rayonnant extérieurement de l'électrode interne aux électrodes externes (13) de manière que ledit fluide s'écoule à l'extérieur du ballon (10) par des pores (30), à l'opposé de ladite électrode interne et dans le tissu à traiter.
