Title (EN) BALLOON CATHETER APPARATUS AND METHOD
(FR) APPAREIL A CATHETER A BALLONNET ET PROCEDE D'UTILISATION
Abstract:
(EN) A surgical device (10) for cleaning and removing obstructing material from within a vascular conduit (2) or other bodily passageway (11). The device (10) comprises a balloon catheter (12) having an independently operable outer woven sleeve (36) having a plurality of mesh openings. The woven sleeve (36) surrounds the radially expandable and contractible balloon (22). In one embodiment, the outer woven sleeve (72) is configured into a predetermined shape through manipulation of the catheter and used to maintain the inflated balloon (62) within that predetermined configuration. In another embodiment, the woven sleeve (106) is radially expanded by the inflated balloon (104) such that the woven mesh is driven into the vascular conduit. The woven sleeve (106) may be used to abrade the surface of the vascular conduit and increase the flow passage or alternatively as traction for various other surgical procedures within the vascular conduit (2).
(FR) L'invention concerne un instrument chirurgical (10) permettant de nettoyer et d'éliminer des matières obstructives présentes dans un conduit vasculaire (2) ou autre passage (11) corporel. Cet instrument (10) comprend un cathéter à ballonnet (12) pourvu d'un manchon extérieur tissé(36), lequel peut être actionné de façon indépendante et présente une pluralité d'ouvertures de mailles. Le manchon tissé (36) entoure le ballonnet (22) à expansion et contraction radiale. Dans un mode de réalisation de l'invention, le manchon extérieur tissé(72) prend une configuration prédéterminée lorsqu'on manipule le cathéter et il est utilisé pour maintenir le ballonnet (62) gonflé selon cette configuration. Dans un autre mode de réalisation, le manchon tissé (106) se dilate radialement sous l'effet du ballonnet gonflé (104) de manière que la gaine tissée est entraînée à l'intérieur du conduit vasculaire. Le manchon tissé (106) peut être utilisé soit pour abraser la surface du conduit vasculaire et augmenter le passage d'écoulement soit comme dispositif de traction pour la conduite d'autres procédures chirurgicales à l'intérieur du conduit vasculaire (2).
