An apparatus (10) for delivery of an infusate into a body lumen (12) to perform thrombolysis comprises a catheter (24) having an infusion section (40) defined by a plurality of infusion ports (42) for delivering the infusate. The infusion ports (42) are spaced axially apart along the length of the infusion section (40). A sheath (50) coaxially surrounds a portion of the catheter (24). The sheath (50) is axially movable relative to the catheter (24) to selectively uncover at least a portion of the infusion ports (42) and thereby control the amount and distribution of the infusate delivered by the infusion section (40).

L'invention concerne un appareil (10) permettant de délivrer une solution intraveineuse dans une lumière (12) d'un organisme pour effectuer une thrombolyse. Cet appareil comprend un cathéter (24) ayant une section de perfusion (40) définie par une pluralité d'orifices de perfusion (42) destinés à céder la solution intraveineuse. Les orifices de perfusion (42) est espacés axialement dans le sens de la longueur de la section de perfusion (40). Une gaine (50) qui entoure de manière coaxiale une partie du cathéter (24), est axialement mobile par rapport au cathéter (24) pour découvrir sélectivement au moins une partie des orifices de perfusion (42) et ainsi contrôler la quantité et la distribution de la solution inraveineuse cédée par la section de perfusion (40).
