Title (EN) METHOD AND APPARATUS FOR MAINTAINING PATENCY IN VIVO
(FR) PROCEDE ET APPAREIL DE MAINTIEN DE L'ETAT OUVERT DE PASSAGES IN VIVO
Abstract:
(EN) An intraluminal stent (10) for maintaining patency in body passages subject to invasive tissue growth includes a cylindrical wall (12) having radial passages (20) therethrough. A mechanism is provided for disrupting cellular growth which penetrates through the passages. The mechanism may provide for mechanical disruption, thermal disruption, or preferably for excision using radio frequency energy. In a specific embodiment, the cylindrical wall is defined by a tubular mesh (51) and the mechanism for disrupting cellular growth comprises parallel wires (52, 54) within the mesh. The wires (52, 54) are connected to an external radio frequency source and act as electrodes in effecting excision using the radio frequency energy.
(FR) Attelle intraluminale (10) destinée à maintenir l'état ouvert des conduits anatomiques sujets à une croissance tissulaire invasive, comprenant une paroi cylindrique (12) dotée de passages radiaux (20) à travers ladite paroi. Un mécanisme permet d'interrompre la croissance cellulaire qui pénètre dans les passages. Ledit mécanisme permet soit l'interruption mécanique, soit l'interruption thermique, soit, de préférence, l'excision à l'aide de l'énergie à haute fréquence. Dans une version spéciale, la paroi cylindrique est définie par un treillis tubulaire (51) et le mécanisme d'interruption de la croissance cellulaire comprend des câbles parallèles (52, 54) qui constituent ledit treillis. Les câbles (52, 54) sont connectés à une source extérieure de haute fréquence et servent d'électrodes pour effectuer l'excision à l'aide de l'énergie de haute fréquence.
