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 The cage is withdrawn into the constraint tube to compress the cage radially inwardly.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.
