    摘要： An apparatus for capturing material within a body lumen includes a shaft carrying an expandable basket device on a distal end thereof. The basket device includes a distal basket carried and a proximal basket carried on the shaft such that the proximal basket is proximal to and spaced apart from the distal basket. Each basket includes an open end communicating with an interior of the respective basket and oriented towards one another. In one embodiment, a tubular middle portion extends between the baskets. In another embodiment, the distal basket includes an actuator coupled to the distal basket open end such that movement of the baskets towards one another causes the actuator to direct the distal basket open end inwardly to allow the open end to be received within the proximal basket to facilitate removal of the apparatus after capturing material within the baskets.

    摘要： 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.
