Title
(EN) BALLOON CATHETER FOR CANALIZATION OF OCCLUDED BLOOD VESSELS
(FR) CATHETER A BALLONET POUR CANALISATION DE VAISSEAUX SANGUINS OCCLUS
Abstract
(EN)
A balloon catheter for canalizing occluded blood vessels comprising a catheter tube (1), a longitudinally extending balloon unit (2) having a longitudinally extending cylindrical section (10) and two end sections (11, 12). The invention is characterized by heat insulating means (13-16) provided at the end sections (11, 12) of the balloon unit as well as by the fact that the cylindrical section (10) is manufactured of heat-conducting material. Hot liquid, possible with the addition of X-ray contrast material, is introduced through said lumen to the internal space enabling the wall surface of a blood vessel (6) to be exposed to thermal action.
(FR)
Le cathéter à ballonet permettant de canaliser des vaisseaux sanguins occlus, comprend un tube de cathéter (1) et une unité à ballonet s'étendant longtitudinalement (2). Ladite unité à ballonet est dotée d'une partie cylindrique s'étendant longitudinalement (10) ainsi que de deux parties terminales (11, 12). L'invention se caractérise par le fait qu'elle comprend des moyens calorifuges (13-16) disposés dans lesdites parties terminales (11, 12) de l'unité à ballonet ainsi que par le fait que ladite partie cylindrique (10) est fabriquée à partir d'une matière calorifuge. L'introduction, à travers ledit passage, de liquide chaud dans l'espace interne, permet d'exposer la paroi superficielle d'un vaisseau sanguin (6) à un procédé thermique, l'addition d'une matière de contraste à rayons X étant éventuellement possible.
