摘要： An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including a proximal end, a distal end, a lumen extending therebetween, and a balloon on the distal end having an interior communicating with the lumen. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The apparatus also includes an actuator for axially compressing the balloon, and a helical member extends between ends of the balloon interior that expands the balloon from a contracted condition to an expanded helical shape when the actuator is activated.

摘要： An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including proximal and distal ends, a lumen extending therebetween, and a balloon on the distal end. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The valve may be biased to be closed, e.g., by a spring element disposed within the balloon. Optionally, the apparatus also includes an actuator for expanding a helical member within the balloon interior, e.g., either before or after expanding the balloon, such that the helical member and balloon may adopt an expanded helical shape for removing material within a body lumen.

摘要： Apparatus and methods are provided for removing obstructive material within a body lumen. The apparatus includes a macerator device deployable from a sheath that includes an expandable cage carried by a shaft and within a constraint tube. The shaft is movable relative to the constraint tube for deploying and expanding the cage within a body lumen such that an open end of the cage is oriented towards obstructive material. The cage is advanced to capture the material or the material is directed into the cage using an expandable member expanded beyond the material and retracted to direct the material into the cage. The cage is withdrawn into the constraint tube to compress the cage radially inwardly. Materials extending through apertures in the cage are sheared off by a sharpened edge of the constraint tube. The smaller, sheared off particles are then aspirated from the body lumen through the sheath.
