CA 2732787

Apparatus are provided for accessing and/or removing material from a body lumen. The apparatus includes a tubular sheath including a shaft having a proximal end and an expandable distal end that is expandable between a collapsed configuration and an expanded, tapered configuration. In one embodiment, the expandable member include inner and outer membranes attached together and to the shaft. Optionally, the inner membrane may include a reinforcement layer and/or the outer membrane may have a longer chord length than the inner membrane, to enhance the expandable member expanding such that a distal opening is defined by the expandable member having s a relatively large diameter tapering proximally to a lumen of the shaft. Optionally, the apparatus may include a dilator and/or one or more treatment devices receivable in the lumen of the shaft.

L'invention porte sur un appareil destiné à accéder et/ou enlever un matériau à partir d'une lumière corporelle. L'appareil comprend une gaine tubulaire comprenant un arbre ayant une extrémité proximale et une extrémité distale déployable qui est déployable entre une configuration repliée et une configuration effilée déployée. Dans un mode de réalisation, l'élément déployable comprend des membranes intérieure et extérieure fixées l'une à l'autre et à l'arbre. Facultativement, la membrane intérieure peut comprendre une couche de renforcement et/ou la membrane extérieure peut avoir une longueur de corde supérieure à celle de la membrane intérieure, de façon à améliorer le déploiement de l'élément déployable de telle sorte que l'élément déployable définisse une ouverture distale ayant un diamètre relativement important s'effilant progressivement vers une lumière de l'arbre. Facultativement, l'appareil peut comprendre un dilatateur et/ou un ou plusieurs dispositifs de traitement pouvant être reçus dans la lumière de l'arbre.
