Beschreibung
Zusammenfassung:	This invention relates to an angioplasty device (10) that is formed from a hollow metallic tube (20), a balloon (30) affixed adjacent the distal end of the tube (20) and being in fluid communication with the lumen (22) of the tube (20), a flexible distal segment connected to the distal end of the tube and a removable hub (40) connected adjacent to the proximal end of the tube (20). The tube (20) is preferably formed from a superelastic material such as nickel-titanium alloy. This invention also relates to various methods of using this angioplasty device (10). L'invention se rapporte à un dispositif (10) utilisé en angioplastie qui est conçu à partir d'un tube métallique creux (20), un ballonnet (30) étant fixé à côté de l'extrémité distale du tube (20) et se trouvant en communication fluidique avec le lumen (22) du tube (20). Un segment distal flexible est raccordé à l'extrémité distale du tube et un embout amovible (40) est connecté adjacente à l'extrémité proximale du tube (20). Le tube (20) est de préférence fabriqué dans un matériau superélastique, tel que l'alliage nickel-titane. Cette invention se rapporte également à divers procédés d'utilisation de ce dispositif (10) pour angioplastie.
