A preferred apparatus for delivering an intravascular drug such as a sclerosing agent (or a microfoam sclerosing agent) to a varicose vein includes a catheter (10) having three concentric tubes (12, 14, 16). The innermost tube (12) has a guide wire lumen (18) and an inflation lumen (20). The distal end of the innermost tube (12) has integral inflatable occlusion balloon (24) in fluid communication with the inflation lumen (20). The intermediate tube (16) has a lumen through which the innermost tube extends. The distal end of the intermediate tube (16) has a self-expanding balloon (28) with a plurality of fluid pores in fluid communication with the intermediate tube lumen. The outer tube (14) has a lumen through which the intermediate tube (16) extends. Sclerosing agent is dispensed through the intermediate tube (16) to pores located at the distal end of the intermediate tube (16) or in the self- expanding balloon (28). Veins are sclerosed as the self-expanding balloon (28) is pulled through and ultimately out of the vein.

L'invention concerne un appareil préféré d'administration d'un médicament intravasculaire tel qu'un agent sclérosant (ou un agent sclérosant micromousse) dans une varice, ledit appareil comprenant un cathéter (10) doté de trois tubes concentriques (12, 14, 16). Le tube (12) situé le plus à l'intérieur possède une lumière (18) de fil-guide et une lumière (20) d'insufflation. L'extrémité distale du tube (12) situé le plus à l'intérieur est pourvu d'un ballonnet (24) d'occlusion intégrale gonflable en communication fluide avec la lumière (20) d'insufflation. Le tube (16) intermédiaire possède une lumière à travers laquelle s'étend le tube le plus à l'intérieur. L'extrémité distale du tube (16) intermédiaire possède un ballonnet (28) auto-expansible pourvu d'une pluralité de pores fluides en communication fluide avec la lumière du tube intermédiaire. Le tube (14) externe possède une lumière à travers laquelle le tube (16) intermédiaire s'étend. Le sclérosant est administré par le tube (16) intermédiaire aux pores situés à l'extrémité distale du tube (16) intermédiaire ou dans le ballonnet (28) auto-expansible. Une veine est sclérosée lorsque le ballonnet (28) auto-expansible est passé dans ladite veine et en est finalement ressorti.
